The global-warming

Svante Arrhenius, a Swedish chemist who lived from 1859 to 1927, first introduced the idea of the greenhouse effect and how increased CO2 emissions from burning fossil fuels could enhance it in 1896. The document discusses the history and causes of global warming, including both natural factors like volcanic eruptions and human factors like industrialization and deforestation that have increased greenhouse gases. If emissions continue unchecked, average global temperatures could rise 2-4°C by 2100, causing problems like more extreme weather, droughts, floods, and hurricanes, as well as risks to human life. Individual actions like using less energy and driving less can help reduce carbon emissions.

Climate change and global warming are causing a greenhouse effect that is impacting agriculture. As the average temperature rises more than 2 degrees Celsius, it will be disastrous for ecosystems and human inhabitation. Some areas will experience increased droughts or floods and rising sea levels. This document discusses the negative effects of climate change such as reduced crop yields in some regions as temperatures rise. However, increased carbon dioxide can positively impact plant growth and photosynthesis for some crops. The document recommends measures to reduce global warming such as planting more trees, using natural gas instead of coal, capturing carbon emissions, and sustainable agriculture practices.

This document discusses global warming, defining it as a gradual increase in the average temperature of the Earth's surface caused by both human and natural factors. It outlines the greenhouse gas effect and ozone layer depletion as the primary mechanisms, noting that increased CO2 and other greenhouse gas emissions from fossil fuel usage, deforestation, and other human activities are major contributors. Effects include melting glaciers/rising sea levels, more extreme weather, impacts on ecosystems and biodiversity, socioeconomic problems, and increased health issues. Solutions proposed are reducing carbon emissions through clean energy adoption, tree planting, and international agreements like the Kyoto Protocol. However, some uncertainties remain around the exact causes and impacts of global warming.

This PPT is about Global Warming and its Effect. This contains all about natural and human disasters like floods, droughts, and glacier melting. This Ppt has a piece of detailed knowledge about global warming and its effect on our earth and our human lives.

The document discusses the uncertainty in predictions of future global warming. The Intergovernmental Panel on Climate Change (IPCC) projects temperature increases between 1.5-6°C by 2100, but there is uncertainty regarding population growth, economic growth, energy use, and the climate system's response. Sea level rise is projected to be 0.2-0.8 meters by 2090s. There are also concerns about potential tipping points where small changes could trigger larger impacts, such as forest dieback increasing carbon emissions or melting Arctic sea ice reducing albedo. The Arctic is already experiencing impacts like sea ice and tundra retreat threatening ecosystems and indigenous peoples. Africa is also highly vulnerable to climate change impacts due to poverty

Scientists have warned that the world's climate is changing rapidly due to human-caused greenhouse gas emissions, primarily from burning fossil fuels. The warming climate is causing glaciers to melt and stronger storms to form. While climate has changed naturally in the past, current changes are occurring faster and are driven by human activity. The climate refers to long-term weather patterns over years in a given location, while weather describes short-term outdoor conditions. Greenhouse gases in the atmosphere, such as carbon dioxide, trap heat and maintain the Earth's warm temperature.
