Climate change is one of the greatest environmental, social and economic threats facing the earth.
The warming of the climate system is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global sea level. Intergovernmental Panel on Climate Change - IPCC foresees in its Fourth Assessment Report published on 2nd February 2007 that, without further action to reduce greenhouse gas emissions, the global average surface temperature is likely to rise by a further 1.8-4.0°C this century. Even the lower end of this range would take the temperature increase since pre-industrial times above 2°C, the threshold beyond which irreversible and possibly catastrophic changes become far more likely.
Human activities that contribute to climate change include in particular the burning of fossil fuels, agriculture and land-use changes like deforestation. These activities cause emissions of carbon dioxide (CO2), the main gas responsible for climate change, as well as of other greenhouse gases. To stop climate change, global greenhouse gas emissions must be reduced significantly.
