Q. What is Climate Change?
Climate Change:As a consequence of cumulative emission of carbon dioxide (a by-product of fossil fuel use) and other chemicals over past two centuries, concentration of these gases in global atmosphere is growing dramatically. These chemicals capture more solar energy within the atmosphere and thus average global temperatures are rising - by about a full degree Celsius (on land) over the past half-century. Rise in global temperatures is causing many serious consequences, including rising sea levels, changes in rainfall, extreme weather and storms and changes in animal and plant habitats.
