Global warming refers to rising average temperatures around the world since 1880 due to increased carbon dioxide in the atmosphere from human activity like burning fossil fuels. The effects of warming are already apparent through melting Arctic ice, glaciers and snow, and temperatures are rising faster in the Arctic. If unchecked, global warming could lead to problems like severe food and water shortages, a rise in sea levels of 7 to 23 inches by 2100, and over a million species facing extinction due to habitat loss and changing ecosystems.
2. What is global warming?
Global warming refers to the rising average
temperature of Earth’s atmosphere and oceans
and it’s projected continuation.
3. Global Warming Facts.
-- average temperatures have climbed 1.4
degrees Fahrenheit around the world since
1880.
-- the rate of warming is increasing.
-- the arctic is feeling the effects the most.
-- Arctic ice is rapidly disappearing.
-- Glaciers and mountain snows are rapidly
melting.
4. Are humans causing it?
--Humans have caused all or most of the
current planetary warming. Humans
caused global warming is often called
anthropogenic climate change.
--Humans are pouring carbon dioxide into
the atmosphere much faster than plants
and oceans can absorb it.
5. What’s going to happen?
-- global warming could lead to large-scale food and
water shortages and have catastrophic effects on
wildlife.
-- sea level could rise between 7 and 23 inches by
century’s end.
-- glaciers around the world could melt, causing sea
levels to rise while creating water shortages.
-- more than a million species face extinction from
disappearing habitat, changing ecosystems and
acidifying oceans.
