The document discusses global warming and its causes. It explains that global warming is driven by greenhouse gases like carbon dioxide and methane that are emitted through human activities like burning fossil fuels and deforestation. These gases trap heat in the atmosphere and cause the planet to warm up. If warming continues, it could lead to problems like rising sea levels from melting ice and glaciers, more extreme weather events, and species extinction as animals struggle to adapt to the changing climate. The document outlines the scientific consensus that human greenhouse gas emissions pose serious risks and that actions are needed to reduce their release into the atmosphere.

1. GLOBAL WARMING

5. What’s the Ozone Layer got to do with it The Ozone layer is another important part of the atmosphere It’s made up of Ozone (a type of oxygen) that protects the earth from too many harmful rays called UVB. Some green house gases damage it – letting in the harmful rays which could raise the earth’s temperature.

8. CLIMATE CHANGE AND HUMAN ACTIVITIES Since the beginning of Industrial revolution around 1750, three human activities have emitted significant amount of greenhouse gases into troposhere: USE OF FOSSIL FUEL : releases large amt of CO 2 and CH 4 into Troposhere. DEFORESTATION, CLEARING & BURNING OF GRASSLANDS TO RAISE CROPS: release CO 2 & N 2 O. RICE CULTIVATION IN PADDIES & USE OF INORGANIC FERTILIZERS: release N 2 O and CH 4

9. It is believed that increased inputs of CO 2 into the atmosphere from human activities will enhance the earth’s natural greenhouse effect and raise the average global temperature of the atmosphere near the earth’s surface. This enhanced greenhouse effect is called as GLOBAL WARMING

10. Fact Sheet FACTS ABOUT INDIA AND CLIMATE CHANGE 01. A one-meter rise in sea level could displace millions of people in India, a country with a coast line of several thousand miles. 02. Annual coal consumption in India has more than tripled since 1980. 03. According to research carried out at Oxford University, the total number of flood zone refugees in India alone could reach anywhere between 20 and 60 million. Sea level rises could also prompt an influx of millions of refugees from Bangladesh.

11. 04. According to the World Bank, India’s carbon dioxide emissions have increased by 88 percent since 1990. 05. Per capita carbon dioxide emissions in India are relatively low. The average Indian is responsible for roughly six percent of the CO2 emitted by the average citizen from the United States. 06. The International Energy Agency expects Indian national energy consumption to more than double from 2002 levels by the year 2020, increasing from 116 to 252 Gigawatts. 07. According to Indian Ministry of New and Renewable Energy the renewable power capacity was around 8 Gigawatts at the end of March 2006, roughly 6.5 percent of the total power generation capacity
