What is Climate Change? • CO2 and methane are heat trapping green house gasses • Average Temperature of the planet is rising
► 1 deg F since 1970, expected 11 degrees by end of century ► May 2010 hottest summer in India since late 1800s, ► 122 deg → 100 deaths in Gujurat, dozens of peacocks dead in forest reserve in U.P. ► Imagine 11 degrees hotter
