Global Warming

Now more than ever humans are becoming a major factor in the future of climate and more importantly climate change. Human actions towards the earth and the depletion of the ozone layer are irreversible. A warmer future could result from human activities in the present by releasing massive amounts of heat trapping gases into the air. (www.maui.net) These greenhouse gases are partially the reason for the 0.5°C rise in the global average temperature recorded over the past 100 years. If the Earth's temperature continues to rise as estimated, global warming could occur more rapidly than any climate change of the last 10,000 years. (www.maui.net) Fossil fuels, which release carbon dioxide when burned, are used to generate electricity, heat and light homes and workplaces, power factories and run cars. The future of Earth's climate may depend partly on the buildup of heat trapping gases, mainly carbon dioxide, methane, and nitrous oxide, in the atmosphere. Industrialized nations are known...
