Climate Change
1. Cause a. Excessive Power Generation of Electricity and Heat Generating electricity and heat by burning fossil fuels such as coal, oil and natural gas causes a large chunk of global emissions. Most electricity is still produced from fossil fuels; only about a quarter comes from wind, solar and other renewable sources. b. Deforestation (Forest Cutting) Cutting down forests to create farms or pastures, or for other reasons, causes emissions, since trees, when they are cut, release the carbon they have been storing. Since forests absorb carbon dioxide, destroying them also limits nature’s ability to keep emissions out of the atmosphere. 2. Effect a. Unexpected Superstorm and Thunderstorm Weather Lightning itself is also linked to variations in upper tropospheric water vapour, and tropospheric ozone, both of which are strong greenhouse gases. Climate model studies show that in a future warmer climate we may have fewer thunderstorms overall, but more intense thunderstorms, which may incre
