onfronting the Climate Crisis: Catholic Theological Perspectives is the culmination of a three-year study by participants in the Catholic Theology and Global Warming
Interest Group of the Catholic Theological Society of
America (CTSA). This interest group was established in
2008 when several members of the CTSA shared a desire to respond
theologically to the complex and vexing problem of global climate
change. Some had already been addressing environmental issues from
the perspectives of the various sub-disciplines of theology in which we
have been trained (e.g., biblical, historical, systematics, ethics) because
inherent in our vocation as theologians is a calling by God to be responsive to the moral issues and signs of our times. Furthermore, we
value our role in relation to the teaching authority of the Church and
wish to be responsive to the bishops who stress living in harmony with
1
God’s creation as “a moral responsibility” ( John Paul II, 1989) and
1
Pope John Paul II’s 1990 World Day of Peace Message was the first papal
statement dedicated to human responsibility for living compatibly with the
natural environment, a teaching he continued in his subsequent encyclicals, messages, statements, and actions to make Vatican City ecologically
“friendly. Pope Benedict XVI, who has been dubbed “the green pope” because of his many teachings on the human relation to God’s creation and
continuing his predecessors’ initiatives in Vatican City, urged world leaders
to “[s]ave the planet before it’s too late” when speaking at the 2007 world
youth rally. Dressed in a green vestment when celebrating Mass in Loreto,
Italy, he underscored the responsibility that humans have toward the natural environment: “New generations will be entrusted with the future of
the planet...which bears clear signs of a type of development that has not
always protected nature’s delicate equilibrium.” He continued: “A decisive
‘yes’ is needed in decisions to safeguard creation as well as a strong commitment to reverse tendencies that risk leading to irreversible situations
of degradation,” and he urged “a strong alliance between man and earth”
(Pullella 2007b).

who specifically urged biblical experts, theologians, and ethicists “to
help explore, deepen, and advance the insights of our Catholic tradition and its relation to the environment,” and especially “the relationship between this tradition’s emphasis upon the dignity of the human
person and our responsibility to care for all of God’s creation” (U.S.
2
Conference of Catholic Bishops 1991, 13). Our efforts to address the
climate crisis in this anthology is an example of a way in which theologians can respond to the Church magisterium.
The first step of our newly-initiated interest group was an examination of the scientific evidence through experts available to each of us
on our campuses, other institutions, and reports by climate experts.
Following this individual endeavor was a group consultation with David Quesada, Ph.D., Associate Professor of Physics at the University
of St. Thomas in Miami who specializes in atmospheric and mathematical physics and has been gathering and interpreting data pertaining to climate change. Our cumulative conclusions were and continue
to be indisputable based on the plethora of data collected and verified
by scientists throughout the world: (1) changes in the global climate
are accelerating; (2) these changes cannot be attributed exclusively
to natural causes; (3) in-depth investigations of possible unnatural
causes point to emissions of carbon dioxide, methane, nitrous oxide,
water vapor, and other greenhouse gases from human activities; (4)
adverse effects from these emissions are ongoing and affecting others who have little part in causing these climate disruptions; and, (5)
future generations will be affected directly and also indirectly through
effects on other species, ecological systems, and the biosphere. The fact
that effective measures are not underway to mitigate these problems,
the need to adapt to what cannot be mitigated, and to avoid suffering
especially of the poor and vulnerable prompted us to probe sources in
the Catholic theological tradition from our various perspectives with
the hope of providing some relevant, meaningful, and helpful ways of
addressing the climate crisis.
2 Other bishops individually and regionally have issued similar calls and
statements pertaining to the need for humans to accept their responsibilities in relation to other species and the natural environment. Statements by
Catholic bishops are available from www.inee.mu.edu.
a Introduction

CoMPelling sCientifiC findings
What is this evidence that prompted our study of the climate crisis
and compelled our production of this anthology? Climatologists and
other scientists recognize that some extraterrestrial and terrestrial factors are primarily responsible for most of the past episodes of changes
in Earth’s climate. Extraterrestrial factors include solar output, EarthSun geometry, and interstellar dust, while terrestrial factors from
oceans, the atmosphere and land include volcanic emissions, mountain-building, continental drift, atmospheric chemistry, atmospheric
reflectivity, land reflectivity, and atmosphere/ocean heat exchange
(Physical Geography.net 2010). However, these factors cannot fully
account for the climate changes that are occurring today, accelerating,
and predicted for the future with various levels of certainty issued by
the Intergovernmental Panel on Climate Change (IPCC), an international association established by the United Nations Environmental
Programme and the World Meteorological Organization in 1988 to
assess peer-reviewed scientific, technical, and socio-economic reports
by scientists throughout the world. On the basis of these data, the
IPCC is charged with the arduous task of providing “a clear scientific
view on the current state of knowledge” about changes in the global
climate and its “potential environmental and socio-economic impacts”
(IPCC 2010a).
The key scientific fact with which the IPCC has had to grapple is a
sharp increase in Earth’s average surface temperature by approximately 1.4 °F (about 0.75 °C) since the mid-nineteenth century (IPCC
3
2007a, 22-23). The key culprits responsible for this increase are human activities through which carbon dioxide, methane, nitrous oxide,
and other “greenhouse” gases are emitted into the atmosphere, intensify the natural greenhouse effect that warms Earth, and increase the
global temperature (Mastrandrea and Schneider 2010, 12-14; IPCC
2007d). According to climate scientists who gather their data from
various sources including ice cores that span thousands of years, tree
rings, the extent of mountain glaciers, changes in coral reefs, and pollen in lake beds, atmospheric concentrations of carbon dioxide, methane, and nitrous oxide have increased markedly since 1750 as a result
of human activities and far exceed pre-industrial levels (IPCC 2007d).

2010 and National Aeronautics and Space Administration (NASA) 2010.

Confronting the Climate Crisis
Scientific reports analyzed by the IPCC indicate that the largest
growth in these gaseous emissions between 1970 and 2004 came from
energy production, other industries, and transportation, while gases
from residential and commercial buildings, forestry (including deforestation), and agriculture sectors grew at a lower rate (IPCC 2007e,
36). Thus, our activities are “forcing” changes on the global climate that
exceed the effects caused by natural factors.
Among these changes are increases in the average global air, land,
and ocean temperatures in the northern hemisphere that are causing
decreases in snow cover and thickness of sea ice; widespread melting
of snow and ice that is causing a rise in the sea level; increases in precipitation in eastern parts of North and South America, northern Europe and northern and central Asia; decreases in precipitation in the
semi-arid land south of the Sahara Desert, the Mediterranean area,
southern Africa and parts of southern Asia; and, an increase in the
intensity of weather events including more extreme tropical cyclone
activity in North America (IPCC 2007e, 36-38).
Physical systems are also adversely affected. For example, glacial
lakes have enlarged and increased in numbers as glaciers and ice melts.
Ground instability has increased in permafrost regions while rock avalanches have increased in mountain regions. Increased runoff is occurring in many glacier and snow-fed rivers. And, lakes and rivers have
warmed in many regions causing changes in the thermal structure of
bodies of water and degraded water quality (IPCC 2007e, 30-33).
Effects on ecological systems are also significant. Within land systems, spring events (e.g., leaf unfolding, bird migration, and egg laying) are occurring earlier, and ranges in plant and animal species are
shifting upward. Within marine and freshwater systems, rising water
temperatures are causing higher levels of salinity, shifts in ranges of
algal, plankton and fish abundance, earlier fish migrations in rivers,
and stresses on coral reefs. The loss of coastal wetlands and mangroves
are attributed to a combination of climate changes and human adaptations of these ecological systems (IPCC 2007e, 32-33).
Adverse effects on human health from human-forced climate change
have also been identified. Among these are increased heat-related
mortality in Europe, changes in infectious disease vectors in parts of
Europe, and earlier onset of and increases in seasonal production of
allergenic pollen in high and mid-latitudes of the Northern Hemisphere (IPCC 2007e, 33).
a Introduction
13
A conclusion from a plethora of climate studies over the past decade
is important to recognize: the sharp increase in the global temperature
has occurred rapidly with uneven effects across geographic, economic,
and social divisions. As John Holdren, Director of Harvard University’s Science, Technology, and Public Policy Program and Co-Chair
of the U.S. President’s Council of Advisors on Science and Technology explained recently, the rise in the global temperature is “rapid
compared with ordinary historic rates of climate change” and “rapid
compared with the adjustment times of ecosystems and human society” (2010, 1). Furthermore, the effects of global climate change “on
human well-being are and undoubtedly will remain far more negative
than positive” (ibid.). Our choices are to mitigate the effects of humandriven climate changes, adapt to them, and suffer (ibid. 3).
Predictions of Future Effects
Because the major greenhouse gases from human activities remain
in the atmosphere for periods ranging from decades to centuries and
more will inevitably be emitted, the IPCC, the U.S. Environmental
Protection Agency, and other major research institutions throughout
the world anticipate that the average surface temperature of Earth is
likely to increase between 1.1-6.4 °C/2 to 11.5 °F (USEPA 2010;
IPCC 2007a, chap 10). This range is the outcome of computer models
into which known data are entered and a range of likelihoods obtained
(see Mastrandrea and Schneider 2010, 23-26). How much and how
quickly Earth’s temperature will actually increase remains unknown
given the uncertainty of the amount of future greenhouse gases, the
planet’s response to changing conditions, and natural influences (e.g.,
changes in the sun and volcanic activity) (USEPA 2010). Putting
these variables into computer models has yielded a “best estimate”
range of a 3.2 to 7.2 °F (1.8-4.0 °C) increase in Earth’s temperature by
the end of the 21st century (USEPA 2010; IPCC 2007a, chap. 10).
This increase will not be evenly distributed: land areas will warm more
than oceans; high latitudes will warm more than low latitudes; warming is expected to occur during the winter months in northern North
America and northcentral Asia; and, summer warming over continents may be accompanied by drier soils in many regions (NOAA
4
2007). The USEPA issued this foreboding conclusion based on research collected by the IPCC: “The average rate of warming over each
4 See also USEPA 2010 and Meehle et al. 2007.
14
Confronting the Climate Crisis
inhabited continent is very likely to be at least twice as large as the rate
of warming experienced during the 20th century” (2010).
Even if emissions of greenhouse gases by human activities are kept
constant at levels that were recorded at the beginning of this century,
the effects will increase because, as already noted, the major gases
already emitted remain in the atmosphere for decades to centuries.
More greenhouse gas emissions at or above levels during the year 2000
would cause further warming and induce many changes in the global climate system during the 21st century that would “very likely” be
larger than those observed during the 20th century (IPCC 2007e, 45).
Among these changes are shrinking sea ice in the Arctic and Antarctic, hot extremes in temperature, heat waves and heavy precipitation
in high latitudes, more intense tropical typhoons and hurricanes, and
5
increased flooding of coastal regions (ibid.).
st
Predictions beyond the 21 century are more dire when considering
the effect on sea levels, even if greenhouse gas concentrations are stabilized, because adding more gases into the atmosphere already containing them in significant qualtities would cause the sea level to rise
for centuries due to the time scales associated with climate processes
and feedbacks (IPCC 2007e, 46; Mastrandrea and Schneider 2010,
21-23)). Prompted by the melting of glaciers and ice sheets on polar
lands, the rising sea level would flood coastlines and inundate lowlying areas, the greatest effects of which will be in river deltas and lowlying islands (Pachauri 2007; Gleick 2010). Increasing atmospheric
concentrations of greenhouse gases, especially carbon dioxide, will
also further acidify the oceans (IPCC 2007e, 52; Turley 2010)).
The survival of some species will also be threatened. According to
IPCC Chairperson Pachauri, approximately “20-30% of the species
assessed in 2007 would be at increased risk of extinction if the global
average temperature increase exceeds 1.5 to 2.5 ºC,” while an increase
that exceeds about 3.5 ºC suggests “significant extinctions” (40-70% of
species assessed) around the planet (Pachauri 2008). Scientists anticipate accelerated adaptations by wild plants and species as they shift
their ranges to inhabit areas with more tolerable temperatures, begin
spring activities earlier, invade habitats of other species, and change
genetically (Leemans 2010).
Closely related to species endangerment and extinction are risks to
ecological systems (Leemans 2010; Turley 2010). The adaptive ability

of forests, grasslands, coastal wetlands, and other ecosystems to adapt
to flooding, drought, wildfires, insect infestations, ocean acidification,
and other disturbances caused by climate changes will be thwarted.
Adaptation is particularly difficult when these disturbances are combined with other drivers of ecological degradation, including land use
changes, pollution, and overexploitation of natural sources. Major
changes in the structure and function of ecosystems are anticipated
with predominantly negative consequences for biological diversity and
for water, food supply, clean air, and other ecosystem goods (IPCC
2007e).
Effects on People, Especially Poor & Vulnerable
Adverse effects of global climate change on ecological systems also
puts our species at risk. According to predictive models developed by
scientists, human-forced climate change will have “serious effects on
the sustainability of several ecosystems and the services they provide
to human society (Pachauri 2007). One of the major effects anticipated is a decrease in the availability of potable water in the mid-latitudes
and semi-arid areas of the planet. While an increase in water availability is anticipated in the moist tropics and at high latitudes, people in
the Hindu-Kush, Himilayan, and Andes mountain ranges where more
than one-sixth of the world’s population currently lives will experience
difficulty in obtaining the water they need as will people in the Mediterranean Basin, western United States, southern Africa, northeastern
Brazil and other semi-arid areas. In already poverty-stricken Africa,
between 75 and 250 million people will be exposed to increased water
stresses by the year 2020, including limited access to potable water
(ibid.; Gleick 2010).
Food scarcity will also be exacerbated in many areas by the year
2020 due to a decline in crop productivity caused by changes in the
global climate. Effects on crop productivity is particularly problematic
in seasonally dry and tropical regions where it is projected to decrease
with small local temperature increases of 1-2 °C). Yields from rainfed agriculture in some African countries could be reduced by up to
50 percent. While initial slight increases in crop productivity are projected at mid to high latitudes where the local average temperature
rises from 1 to 3 °C, productivity is expected to decrease subsequently
(IPCC 2007e). The same pattern of an initial increase in crop productivity followed by a decrease is anticipated globally (ibid.).
16
Confronting the Climate Crisis
Millions of people are projected to experience yearly floods due to
sea level rise by the year 2080 than people experience today. Particularly vulnerable are megadeltas of Asia whose major cities, including
Shanghi, Dhaka, and Kolkata, cities on the coast, and cities in river
flood plains whose industries and businesses are closely linked with
climate-sensitive resources (Pachauri 2008; IPCC 2007e). Small
islands off the coasts of Asia and Africa are especially vulnerable.
Within these at-risk areas, poor communities will be most affected
(IPCC 2007e; 2007b) because their sensitivity to the adverse effects
of climate change is exacerbated by their poverty, food scarcity, malnutrition, and inaccessibility to other necessities of life. Adding to their
impoverished circumstances, the poor are especially vulnerable to debilitating trends in economic globalization, regional conflicts, and diseases, including HIV/AIDS (Pachauri 2007).
The health of future people is also at risk as the global climate
changes. Malnutrition, deaths, diarrhoeal and other diseases, injuries
due to extreme weather events, and increased frequency of cardio-respiratory diseases due to higher concentrations of ground-level ozone
6
in urban areas are included in these projections (IPCC 2007e). While
residents in temperate areas may benefit initially by fewer deaths from
cold exposure and combinations of other factors (IPCC 2007e), any
benefits will be outweighed by the negative health effects of rising
temperatures, especially in developing countries (ibid.; 2007b). Poor
people are most vulnerable to adverse health effects caused by forced
climate change, and education, health care programs, and public health
initiatives are crucial for shaping healthy populations to prevent more
adverse effects (IPCC 2007e; 2007b).
When accepting the 2007 Nobel Peace Prize on behalf of the Intergovernmental Panel on Climate Change, Chairman Rajendra
Pachauri underscored the equity implications of climate change and
how they will affect some of the poorest and most vulnerable communities of the world:
One of the most significant aspects of the impacts of climate
change, which has unfortunately not received adequate attention
from scholars in the social sciences, relates to the equity implications of changes that are occurring and are likely to occur in the
future. In general, the impacts of climate change on some of the
poorest and the most vulnerable communities in the world could

17
prove extremely unsettling. And, given the inadequacy of capacity, economic strength, and institutional capabilities characterizing
some of these communities, they would remain extremely vulnerable to the impacts of climate change and may, therefore, actually
see a decline in their economic condition, with a loss of livelihoods
and opportunities to maintain even subsistence levels of existence
(Pachauri 2007).
He also called attention to the potential conflicts resulting from human-forced climate change and lamented the IPCC’s failure to provide directions for mitigating them. He expressed concern about conflicts that may arise when access to clean water, food availability, stable
health conditions, ecosystem resources, and secure settlements are disrupted by changes in the climate. A major potential source of conflict
that he identified is the migration and movement of people from one
area to another. Though usually temporary and often from rural to
urban areas in response to floods, famine and warfare, the migration
and movement of people from climate change impacts may become
highly problematic for them, for the people of the regions to which
they are relocating, and for efforts to establish a peaceful global society.
To address these potential threats, Pachauri urged conducting an “indepth analysis of risks to security among the most vulnerable sectors
and communities impacted by climate change across the globe” (ibid.).
efforts, hoPes, and errors
Though climate scientists have been collecting and measuring data
for several decades that point to an increase in the global temperature and, more recently, to the ongoing effects on people, other species,
ecosystems, and the biosphere, and though they have developed increasingly sophisticated models for predicting the likelihood of future
effects that are ominous even at a low range of certainty, little has been
accomplished at national and international levels of decision-making
to mitigate human-forced climate change. The United States government has been especially remiss by failing to pass comprehensive legislation aimed at addressing the climate crisis, though anticipation was
high during the first two years of the Obama Administration when
the House of Representatives and the U.S. Senate were controlled by
Democrats who campaigned on platforms committed to mitigating
this crisis. Little hope lingers for effective climate legislation during
the 2011-2013 congressional year. Meanwhile, the U.S. has retained
18
Confronting the Climate Crisis
the dubious distinction of emitting the largest amount of greenhouse
gases per capita (Netherlands Environmental Assessment Agency
2007; Knickerbocker 2007). This is not surprising given our nation’s
highly industrialized economy that thrives on energy generated primarily with non-renewable sources and uses energy less efficiently
than possible.
Internationally, efforts to address climate change have been officially
ongoing since 1988 when, as already noted, the United Nations collaborated with the National Oceanic and Atmospheric Administration
(NOAA) to establish the IPCC that they charged with collecting, assessing, and drawing conclusions from peer-reviewed reports to serve
as basis for informed decision-making. Another milestone occurred in
1992 when the UN established the Framework Convention on Climate Change (UNFCCC) through which environmental ministers of
UN countries that signified their desire to participate as Parties of the
7
Framework Convention would meet to discuss and take joint action
on climate-related issues. At their third meeting (Conference of the
Parties–COP 3) held in Kyoto, Japan in 1997, the ministers developed and signed on behalf of their nations a protocol that committed
them to reducing greenhouse gas emissions to 1990 levels by 2012
8
through methods each nation determined (UNFCCC 1997). The
United States was among the first signatories of the Kyoto Protocol,
but neither President Bill Clinton nor President George Bush submitted it to the U.S. Senate for ratification, ostensibly because elected
officials feared jeopardizing the economic well-being of the U.S if
attempts were made to meet Kyoto emission targets. Detailed rules
for implementing the Protocol were adopted at COP 7 in Marrakesh
(UNFCCC 2001), nearly two hundred nations have ratified and/or
accepted Kyoto Protocol goals, but the extent to which they will be
met has yet to be ascertained.
7
The signatory Parties of the Convention number 194–193 nations and
one regional economic integration organization; see list of parties, dates
signed, ratified, and effective at http://unfccc.int/essential_background/
convention/status_of_ratification/items/2631.php.
8 The Kyoto Protocol placed a heavier burden on industrially developed
nations under the international law principle of “common but differentiated responsibilities” and specified three market-based mechanisms through
which to meet their emission targets in cost-effective ways: emissions trading, clean development, and joint implementation.
a Introduction
19
Despite high hopes for COP 15 held in Copenhagen in 2009, involvement of many non-government agencies and youth groups (in
which a former outstanding environmental ethics student of mine
participated), a stimulating pre-conference featuring the latest climate
science, and eager anticipation that the top leaders of the world’s nations would meet on the last day to bind their nations in a rigorous
plan to address the climate crisis, little progress was made over the
two weeks of the summit. The international media, UNFCCC web
site, and my reliable student reported extensively on friction between
developing and developed nations, and the social communication network was alive with minute-to-minute accounts of the proceedings,
encounters, and disappointments. Representatives of developing nations balked at highly industrialized nations’ pressuring them to curtail their emissions of greenhouse gases without offering adequate
financial and technical assistance to facilitate their opting for cleaner
coal technology, energy efficient strategies, and ability to tap renewable
energy sources. Developing and developed nations also strongly disagreed over means of monitoring, verifying, and reporting reductions
in emissions of greenhouse gases. Shortly before COP 15 was scheduled to end in failure, the heads of state arrived and endeavored to
broker a positive outcome from the bleak scenario, and an “accord” was
drafted by the United States, China, India, Brazil, and South Africa.
The accord was vigorously debated by opponents and proponents, recognized (not adopted), and eventually signed by representatives of nations who committed to reporting by January 31their individual plans
for reducing greenhouse gas emissions. The twelve provisions of the
Copenhagen Accord began with the following commitment:
We underline that climate change is one of the greatest challenges
of our time. We emphasise our strong political will to urgently combat climate change in accordance with the principle of common but
differentiated responsibilities and respective capabilities. To achieve
the ultimate objective of the Convention to stabilize greenhouse
gas concentration in the atmosphere at a level that would prevent
dangerous anthropogenic interference with the climate system, we
shall, recognizing the scientific view that the increase in global temperature should be below 2 degrees Celsius, on the basis of equity
and in the context of sustainable development, enhance our longterm cooperative action to combat climate change. We recognize
the critical impacts of climate change and the potential impacts of
20
Confronting the Climate Crisis
response measures on countries particularly vulnerable to its adverse effects and stress the need to establish a comprehensive adaptation programme including international support (UNFCCC
2009, #1).
9
Though reported in the media as a failure, the nations signing the
Copenhagen Accord recognized for the first time the need to stay below a 2 ºC increase in the global temperature, the possibility that this
increase may be too high, and the need for a reassessment in 2015 to
consider “strengthening the long-term goal” from 2 ºC to 1.5 ºC (UNFCCC 2009, #12). Among other articles in this accord was a commitment by the developed nations to provide “adequate, predictable and
sustainable” financial and technological support to developing nations
so they can reduce their emissions. The signatories also committed
to establish a “Copenhagen Green Climate Fund” through which the
developed countries will be able to secure funding from public and
private sources to finance “meaningful mitigation actions” by “the most
vulnerable developing countries, such as the least developed countries,
small island developing States and Africa” (ibid. #8-10). By January
31, 138 nations had signed the Copenhagen Accord, some plans to
reduce emissions had been submitted and appended to it, and others
were at various stages of completion. Because signing this accord was
voluntary instead of binding as some COP 15 ministers and many
watchers had hoped, the first chairperson of the UNFCCC described
the accord outcome as a “shock” that he hope will stimulate serious discussion about what nations are willing to do to mitigate human-forced
climate change (Cutajar 2010).
As I write this introduction, COP 16 has just ended in Cancun,
Mexico where 192 nations were represented. Apparently the environmental ministers had not been sufficiently shocked by COP 15. An
overarching and binding agreement to slash emissions of greenhouse
gases was not struck, and disagreements between developing and developed nations that stymied the ministers’ progress in Copenhagen
9 After emerging from 13 hours of talks with other world leaders and
reaching agreement on the principles of the accord, President Obama was
quoted widely in the media as stating that the progress made was “meaningful” but “not enough.” British Prime Minister Gordon Brown viewed the
accord as a “vital first step we are taking towards a green and low carbon future for the world.” He also stated: “I know what we really need is a legally
binding treaty as quickly as possible” (Vidal et al. 2009).
a Introduction
21
also stymied the 2010 proceedings—the amount of emissions that
need to be cut and how much the developed nations would contribute
to developing nations’ mitigation and adaptation efforts (e.g., Rothbard and Rucker 2010). Especially contentious was a proposal to extend the Kyoto Protocol commitment period beyond 2012 by which
most developed nations committed to cut their greenhouse gas emissions or to inaugurate a new commitment period that might attract
nations like the United States that had not ratified the Kyoto Protocol
(Buckley and Wynn 2010). After extending the conference another
day so the delegates could try to produce a positive outcome, the min10
isters approved “urgent action” to cap the global temperature rise to
no more than 2 ºC/3.6 ºF over pre-industrial levels while asking for a
study on strengthening the commitment to a lower degree rise, creating the “Green Climate Fund” for which they would aim to raise $100
billion by 2020 for aiding developing countries’ efforts to mitigate
and adapt to climate change, and initiating several measures aimed at
protecting tropical forests and sharing new clean energy technologies
(UNFCCC 2010c). However, they put off until COP 17 a decision on
extending the Kyoto Protocol period or inaugurating another new legally-binding protocol (Vidal and Goldenberg 2010; DeSousa 2010).
Plaguing deliberations at Copenhagen and Cancun were questions
about the believability of climate scientists’ research that surfaced before COP 15 officially began and carried over into COP 16. The tenor
at Copenhagen was marred considerably by the disclosure of e-mails
from a climate research laboratory at the University of East Anglia
suggesting that some scientists were attempting to suppress findings
by other climatologists that did not agree with their own. Following
this disclosure was subsequent evidence of improprieties reflected in
the 2007 IPCC reports pertaining to the rate at which the Himilayan
glaciers are melting and direct connections made between catastrophic
events and human-forced climate change (e.g., Leake 2010). After investigating the Himilaya glacier issue reported in a paragraph of the
978-page Working Group II report and a companion reference in the
Synthesis Report, the IPCC Chairman, vice-chairs, and co-chairs of
the report expressed their “regrets” for the “poorly substantiated” conclusions that resulted from improperly following “well-established
standards of evidence” and “poor application of IPCC procedures”
when preparing those sections of the report (IPCC 2010b). The
10
COP 16 approval is significant when compared with COP 15 recognition.
22
Confronting the Climate Crisis
IPCC proceeded to establish guidelines for using scientific literature
in its reports, addressing errors in previous assessment reports, and
treating uncertainties consistently (IPPC 2010c).
Collection and assessment of peer-reviewed research are underway
for the next IPCC report, and we can only hope that lessons learned
from 2007 are reflected in it so the bases for decision-making by the
nations are well grounded in facts, methods for assessing them and
identifying ranges of certitude about present and future effects are instituted and carefully used, and options for addressing these effects are
well substantiated. Every climate scientist and every climate research
institution should be able to benefit in some way from errors that have
been committed and from allegations levied by climate change skep11
tics (e.g., MacRae 2010; Holland 2007) who may help purge the
process from errors and improve methodology in assessing research
findings. Theologians who feel compelled to address the climate crisis
will also benefit through verifiable scientific findings and interpretations thereof upon which to reflect in meaningful ways. We rely upon
scientists to provide the facts and realize that we need a heavy dose of
the virtue of fortitude to face and act on them.
Nevertheless, despite the few but significant improprieties discovered in the IPCC’s 2007 reports and the points made by skeptics who
argue against attributing any aspect of the warming planet to human
causes, the consensus of the scientific community persists: the temperature of Earth is increasing; human activities that spew greenhouse gases into the atmosphere are forcing the temperature rise;
and, adverse effects are experienced now and projected for the future
at various levels of certainty. Scientists have banded together to issue
statements about this consensus (e.g., “Open Letter” 2010; American
Institute of Biological Sciences 2009) so decision-makers accept the
fact that human activities are forcing the temperature of our planet to
rise, adverse effects are occurring now and projected to continue in the
future, and changes in how we are functioning must be made now to
mitigate these adversities.
In the meantime, industrialized countries continue to spew excessive greenhouse gases into the atmosphere while China, Malaysia, and
other countries that are developing industrial economies are emitting

increasing amounts. China is leading the way as the largest emitter
overall, while the U.S. remains the largest emitter per capita (Netherlands Environmental Assessment Agency 2007; Knickerbocker 2007).
As the latest IPCC report indicates, all countries with portfolios of
greenhouse gas emissions have options for reducing them. These options include energy conservation and energy efficiency improvement,
the use of more renewable energy sources, recovery and abatement of
methane and nitrous oxide emissions of various sources, sequestration
of carbon in forests and soils, and carbon capture and storage (2007c).
However, developing nations need help in tapping their options, and
the Green Climate Fund outlined in the Copenhagen Accord and established by the Cancun Accord is surfacing as a vital vehicle to helping them help themselves. Hopefully, their efforts will have the effect
of slowing the rate at which Earth’s temperature increases.
CatholiC aCtion
As indicated in texts by the U.S. Catholic bishops and popes John
Paul II and Benedict XVI, the Church magisterium is cognizant of
climate science and concerned about human activities that are forcing the temperature of Earth to increase. Their teachings are covered
at length in two essays of this anthology. One by Connie Lasher and
Msgr. Charles Murphy explores the Christian humanism of popes
John Paul II and Benedict XVI and its significance for addressing human-forced climate change. In the second pertinent essay, I explore the
Catholic social teachings of popes from Leo XIII and successor popes
on the principles of subsidiarity, solidarity, and preferential option for
the poor. References are made to papal texts and pastoral statements
by bishops in other essays of this anthology, thereby demonstrating
our engagement with magisterial teachings.
Action is not limited to these teachings, however. During the pontificates of John Paul II and Benedict XVI, Vatican City has become
progressively “green” through conservation efforts that include recycling, using photovoltaic cells on buildings to produce electricity, and
hosting a scientific conference to discuss global warming (Pullella
2007a). At a conference organized by the Vatican’s Council for Justice
and Peace, Bishop Bernd Uhl of Freiburg told the scientists, environment ministers, and leaders of various religions from twenty countries
who had gathered in Vatican City: “Climate change is one of the signs
of the times affecting the Catholic Church as a global organization.
24
Confronting the Climate Crisis
The Catholic Church must take a stand on this present-day and urgent question” (Pullella 2007a).
Efforts have been initiated at national and diocesan levels to study
the climate change issue, to advocate activities aimed at mitigating
human-forced change, and to lobby for appropriate legislation with
special attention to minimizing the suffering of poor and vulnerable
people who will be most severely affected by climate change. Having issued Global Climate Change: A Plea for Dialogue, Prudence, and
the Common Good in 2001, the text of which appears below, the U.S.
Catholic Conference of Bishops (USCCB) through its Environmental Justice Program has been assisting these efforts. A major national
initiative by the USCCB in partnership with Catholic Relief Services
and other organizations is the Catholic Coalition on Climate Change
which encourages “a more thoughtful dialogue about ways the Catholic community can respond to climate change” and “invites Catholics to
participate in a new initiative offering a distinctively Catholic perspective on global climate change” (USCCB and CRS 2010). The impressive array of Catholic organizations involved with the U.S. Catholic
12
bishops and Catholic Relief Services in the Coalition (CCCC 2010)
should inspire hope for action aimed at mitigating the effects of human-forced climate change. Among the thoughtful activities of the
Coalition are the Catholic Climate Covenant’s encouraging the faithful to take the St. Francis Pledge to pray and reflect on the duty to care
for God’s Creation and protect the poor and vulnerable; to learn about
and educate others on the causes and moral dimensions of climate
change; to assess how we as individuals and in our families, parishes,
and other social and economic affiliations contribute to climate change
by our energy use, consumption, and wastefulness; to change our
choices and behaviors by reducing the ways in which we contribute to
climate change; and, to advocate for Catholic principles and priorities
in climate change discussions and decisions, especially as they impact
those who are poor and vulnerable (CCCC 2010). Through its web
site, the Coalition shares inspiring stories about actions other people
are taking and gives practical, timely tips for minimizing each person’s

impact on the climate in daily activities. One of the Coalition’s most
recent projects is training Catholic Climate Ambassadors—leaders
from across the nation who become immersed in climate science and
Catholic teaching on caring for God’s creation and the poor and who
offer presentations to parishes, schools, diocesan ministry professionals, and others on the Church’s teachings.
As a participating organization in the Catholic Climate Change Coalition, Catholic Relief Services (CRS) is helping “to strengthen the
ability of the most vulnerable communities in the developing world to
respond to and prepare for the effects of climate change” by providing
education and training to people in poor communities on ways to reduce their vulnerability to the effects of climate change in the areas in
which they live (USCCB and CRS 2010). CRS recognizes that people
who live in poverty “contribute least to climate change but they are
likely to suffer its worst consequences” (e.g., increasingly limited access
to water, reduced crop yields, and more widespread disease) with few
resources with which to adapt and respond, thereby making their lives
more difficult and increasing their suffering (ibid.).
Thus, the teaching authority of the Church and Catholic organizations are busily engaged in efforts to address climate change at many
levels of endeavor. Theologians can help, as the U.S. Catholic bishops
urged in 1991, by using our skills to identify, explain, and demonstrate
various theological perspectives from which to think about the human
person in relation to one another and to other species, ecological systems, and the biosphere of our planet that are imperiled now and will
be imperiled into the future by our climate disruptive activities.
resPonding theologians
In this anthology, we share what we have found and reflected upon
that we think is helpful toward addressing the climate crisis. Our first
three essays explore promising themes in the Bible. Suzanne Franck
focuses on Wisdom literature that conveys belief in God’s dynamic
presence as wisdom that permeates the world, establishes an interrelationship among humans and other creatures that constitute the
world, heightens that relationship by becoming incarnate as Jesus
Christ, and requires that we intrinsically value the world as a reflection of God. Challenging us to live wisely in the world today in ways
that avoid forcing an increase in the global temperature, she suggests
several approaches including reflection on the sacramental character
26
Confronting the Climate Crisis
of the world from the perspective of the Incarnation to motivate us
to live wisely, accepting the overwhelming evidence that our climatedisruptive activities are jeopardizing the opportunity for people in the
future to experience God’s presence in the world, and engaging conscientiously in the ongoing story of creation as co-creators with God
who assure that future generations will be able to live in a world that is
charged with the grandeur of God. Ann Marie Kidder demonstrates a
new hermeneutical approach used by biblical scholars to read Romans
8 and pertinent parts of other letters written by St. Paul and his followers for their theological significance today. Finding in these texts
an intricate interplay and shared destiny of creation and covenant in
the scheme of salvation through Christ, she points to Paul’s understanding that God’s glory is manifested first in humans and second in
God’s creation. Humans are distinguished by knowing our connection with other living and non-living creatures and knowing that they
suffer when we sin and rejoice when we are redeemed. Applying this
motif to the climate crisis, Kidder explains that we can experience the
groaning of Earth in tandum with the Spirit of Christ working within
us to have compassion for other species, the land, the air, and the waters whose role as “cheerleaders” of our salvation is jeopardized by our
climate-forcing actions. Vincent Pizzuto explores the Christ hymn in
Colossians 1 from an ecological-hermeneutical lens to understand the
significance of the Pauline author’s depiction of humans in relation
to other creatures, and he finds a soteriology in which humans are
created with the world and saved with the world through the presence and power of Christ who permeates and heads the cosmic body.
While all creatures are interconnected through Christ in this scheme
of creation and redemption, Pizzuto explains, and all are members of
Christ’s cosmic body who together reflect God’s presence in the world,
human creatures are most reflective of Christ’s headship through our
self-reflective consciousness and moral agency that requires us to
act justly in relation to others with whom we constitute the cosmos.
Harming Earth by forcing changes in the global climate constitutes
harming the body to which we belong, and we are morally responsible
for attending to the wounds we are inflicting.
The next four essays draw primarily upon the work of two revered
theologians in the Catholic tradition—St. Bonaventure of Bagnoregio (1217-1274) and St. Thomas Aquinas (1224/5-1274). Focusing on Bonaventure’s trinitarian theology with special attention to
a Introduction
27
his Christology, Dawn Nothwehr emphasizes his hope-filled vision of
the intimately related and interconnected reality of God, the divinehuman Christ, and the world in which humans are called to serve as
its guardians and co-creators with God. Bonaventure knew long ago
that the faithful need to recognize this reality within which we live,
acknowledge our creaturely status as loved and sustained by God, and
act in ways that show our respect for the interconnections and interdependence of all creatures. Answering the question “How shall we
live?” from the perspective of Bonaventure’s Christology, Nothwehr
urges us to develop the virtue of humility so we can realize that God
desires a relationship not only with us but also with the entire world,
to develop the virtue of poverty by releasing ourselves from our arrogance and consumerism, and to develop the virtue of obedience
by living lovingly within the world that our loving God has held in
dynamic existence for nearly 14 billion years. Daniel Scheid finds in
Aquinas’ theology of creation a “robust” understanding of the common good that unites God, the universe, and humanity in a holistic
paradigm that is helpful for addressing the climate crisis. From Aquinas’s tripartite understanding that the whole universe surpasses in
excellence any individual creature, the most valuable feature of the
universe is the orderly functioning of its constituents, and the entire
universe best glorifies God, Scheid urges respect for the goodness of
Earth, cooperation with the other constituents of Earth for our mutual sustainability, humility about our place in the world in relation to
the contributions that other species, ecological systems, and the biosphere make to the planetary common good, and upholding the life
and dignity of human persons who have the unique capacity to love
one another. William French draws upon Aristotle’s ethic of the “fitting
response” and Thomas Aquinas’ understanding of self-mastering human acts, vincible and invincible ignorance, and the virtue of prudence
to stress the need for knowing the full range of internal and external
costs incurred when human actions disrupt the global climate. Failing
to include external costs of production and use imposed on others or
future generations thwart an individual’s or a society’s ability to know
the full impact of their actions and to make decisions about mitigating their effects. Arguing that these “hidden” costs need to be internalized through green taxation schemes and tax shifting policies, French
points to the educational and consciousness-raising benefits they can
provide by helping us recognize the nature and ramifications of our
28
Confronting the Climate Crisis
actions. William George brings his continuing interest in international
law to the question of how to respond theologically to the climate crisis in cogent and constructive ways. Stressing the need for theologians
to be as informed as possible about international law principles and
institutions that deal with climate issues, he draws upon Aquinas and
one of his intellectual heirs in the 20th century, Bernard Lonergan, to
explore two interrelated points of convergence between Catholic theology and international law that can open theologians to reflection—a
method they share and virtues they affirm (e.g., justice, charity, and
prudence). George explores in depth Aquinas’ systematic treatment
of the moral virtue of prudence and applies each component to pertinent aspects of international law for addressing the climate crisis.
Though foresight provides the most direct link between prudence and
intergenerational justice in theology and international law, other aspects of prudence work in tandem with foresight, including memory,
understanding, docility, shrewdness, reason, circumspection, and caution. He recognizes with Aquinas how little humans can accomplish
in addressing the climate crisis apart from God’s grace.
In the next group of essays, the works of the scientist-mystic Teilhard de Chardin (1881-1955), theologians Karl Rahner (1904-1984),
Bernard Lonergan (1904-1984), and Hans Urs von Balthasar (19051988), and the self-styled “geologian” Thomas Berry (1914-2009) are
explored. Having immersed himself in Teilhard’s writings for many
years, Robert Faricy reflects on the value-supportive world view of the
paleontologist and mystic who integrated evolutionary biology and
Christian theology to produce an understanding that God is continuously creating the world of many, suffusing it with the divine presence
heightened by the Incarnation, and influencing its convergence from a
multiplicity to its fulfillment and unification in Christ. Humans have
emerged out of this process with the capacity to be responsible participants who should feel motivated to mitigate human-forced climate
change. Richard Kropf has devoted decades to studying Teilhard and
focuses his essay on the confluence of the Club of Rome/MIT study
on limits to growth and Teilhard’s analysis of human evolutionary development and the final transformation of the material energies of the
universe into “Ultra-humanity.” Particularly problematic to reaching
this culmination, Kropf notes, is the human population increase that
is stretching planetary resources and forcing us to make some major
choices today about the fate of our species. Most poignant in Kroft’s
a Introduction
29
analysis is his pointing to Teilhard’s thinking late in his life that God
might have a greater purpose for the universe than one planet or one
species. Aiming to clarify the kind of dialogue needed for theologians
to address the climate crisis, Denis Edwards draws from Karl Rahner’s
theology five interpretive principles grounded in the belief that the
world is the place where we encounter God and five interpretive principles from a scientifically informed ecological consciousness grounded
in the reality that our actions are forcing changes in the global climate.
Both “sides” need to be heard for a fruitful dialogue, Edwards insists,
challenges they make to one another recognized, and critical questions
they raise for one another answered to yield helpful outcomes. Richard
Liddy presents three levels of Bernard Lonergan’s heuristic framework
for analyzing questions that arise when addressing the climate crisis:
the basic world view of emergent probability that surfaces from an
analysis of contemporary scientific findings; a fundamental analysis
of human biases against recognizing how we “ought” to act from what
“is”; and, an illustration for answering questions about God as the absolute intelligence and basis for human intelligence when faced with
lack of human intelligence and absurdities that are driving an increase
in Earth’s temperature. Lonergan’s analysis of the dynamics of redemption and conversion through God’s grace is also helpful, Liddy explains,
for bringing about change of our minds and in our hearts about how
we are functioning within our planet. Anthony Sciglitano finds in “deep
ecology” a suitable dialogue partner for Balthasar who also critiques
viewing other species exclusively as instruments for human use, recommends contemplation of the environment, and believes it should
inspire responses of wonder, reverence, and joy. Though finding these
convergences, Sciglitano points to challenges Balthasar makes to deep
ecology’s antipathy for divine transcendence and low esteem for human moral responsibility. Balthasar contributes a theological perspective to a serious difficulty within secular ecological thought generally
and deep ecology in particular, Sciglitano argues, and he names and
explains Balthasar’s “doxological ecology” which supports a communal
practice rooted in contemplation that respects Earth in all its diversity
as having an intrinsic value and needing human care. Finally, Peter Ellard outlines key aspects of the groundwork Thomas Berry provides
for “a dark green Catholic theology” that stresses the history of the
unfolding of the universe and the reality of marvels that we encounter
through our senses, fail to recognize, and destroy. With Berry, Ellard
30
Confronting the Climate Crisis
endorses thinking about the universe as “a community of subjects,
not a collection of objects,” the need to reinvent the human within
the context of this community, and engagement in “the great work” of
developing an intimate relationship with Earth and its constituents as
subjects instead of merely objects for human use. Ellard also endorses
Berry’s suggestion that we need to put problematic aspects of the Bible, doctrines, and ideas within the Catholic theological tradition “on
the shelf ” for a while until we are knowledgeable about the universe
story from which our species emerged, transform our destructive and
instrumental attitude toward our planetary home, and acknowledge
the human place within her.
Our next two essays emerge variously from feminist theology. Colleen Mary Carpenter finds highly problematic our failure to recognize
the world as revelatory of God’s goodness and God’s presence. Concerned that this sacramental sense of God in and through the world is
threatened by the damage we are inflicting on Earth through our climate-forcing actions, she draws upon two different options that have
surfaced in the recently revived field of pneumatology to imagine how
we can think about God’s presence in the midst of climate change.
One option proposed by Mark Wallace is to understand the Holy
Spirit as wounded, traumatized, and in agony over ecological degradation, while the other proffered by Elizabeth Johnson understands the
Holy Spirit as a vivifying presence that gives us hope in the midst of
the destruction and death we have unleashed on the world. Carpenter
examines these options critically, opts for aspects of both, and urges
embracing them imaginatively in liturgies with the hope of moving
beyond the climate-disruptive and planet-destructive behaviors that
have become “normal” in our lives. A pioneer in the development and
understanding of feminist theology, Anne Clifford turns to another
kind of experience in a particularly vulnerable part of the world—subSahara Africa—where biologist and Nobel laureate Wangari Maathai
has led disempowered and subordinated women to become proficient
in growing and planting thousands of trees that are indigenous to the
region but were almost decimated by European colonizers. Clifford
explains Matthai’s concern about and efforts to mitigate the negative
effects the colonial patriarchal order had on the natural environment
and women, identifies convergences in Maathai’s eco-feminist perspective and Catholic social teaching on the climate crisis, and points
a Introduction
31
to the hope the Green Belt Movement has given to women for their
improved status in Kenyan society and a more life-sustaining climate.
In the final group are essays and documents dedicated to Catholic
social teaching. Connie Lasher and Msgr. Charles Murphy analyze the
Christian humanism that surfaces from the theology-environment
dialogue in which popes John Paul II was engaged and Benedict XVI
is currently engaged, finding features that are both noteworthy and
promising for confronting the climate crisis. Among these features is
an understanding of the world as God’s “gift” to all humans and our
species’ distinct capacity among creatures to accept this gift by contemplating the world through which the mystery of God as the source
of all reality is revealed, by respecting the integrity of the world as
a common heritage of humans now and in the future, and by acting
together with a sense of shared responsibly for the natural environment. My essay provides an overview of three Catholic social teaching principles: solidarity as an understanding that all people should be
engaged in seeking their common good; subsidiarity as an method for
making decisions beginning at the most local level; and opting to give
preference to the poor in decision-making as demonstrated in the life
and teachings of Jesus Christ. Though these principles can help guide
our efforts to address the climate crisis in the interests of humans, I
propose expanding solidarity to include all species and systems that
constitute our planet—Earth solidarity, reconfiguring subsidiarity to
conform to biological regions in which humans function with other
species and abiota—bioregional subsidiarity, and including future
people, species and ecological systems among the poor for whom we
must show preference when making decisions about mitigating and
adapting to climate change. The next entry is Global Climate Change:
A Plea for Dialogue, Prudence, and the Common Good that was issued
by the U.S. Catholic bishops in 2001 and is introduced here by Jane
Russell who underscores the attention the bishops give to the virtue
of prudence for confronting the climate crisis. Closing this anthology
is Pope Benedict XVI’s 2010 World Day of Peace Message, If You
Want to Cultivate Peace, Protect Creation, a document he issued twenty
years after the first papal statement dedicated to the human-Earth relationship. We are grateful for permission to include these magisterial documents in Confronting the Climate Crisis: Catholic Theological
Perspectives.
