    Global warming

    About 75% of the solar energy reaching the earth is absorbed by the earth’s surface, which increases the temperature. The rest of the heat radiates back to the atmosphere.

    The carbon dioxide in the atmosphere has increased by 31% since pre-industrial times, causing more heat to be trapped in the lower atmosphere. Many countries have signed a convention to reduce Green House Gases (GHG) under the United Nations Frame work convention on climate change (UNFCC).
