Global Warming
We believe that global warming is currently the most urgent environmental challenge facing the planet. The negative impacts have already begun in many parts of the world. One of the key causes of global warming is the vast amounts of CO2 humans produce due to the burning of fossil fuels such as coal, oil, and gasoline used in our many forms of transportation and power generation.
Climate Change Explained
The earth's temperature is normally regulated by naturally occurring "greenhouse gases" (GHGs) including carbon dioxide, methane, nitrous oxide and water vapour that trap the sun's heat and prevent it from being lost to space. Without this "greenhouse gas effect" the earth's temperature would average minus 15 degrees Celsius (5 degrees F) instead of the actual 18 degrees Celsius (65 degrees F) that makes life on earth possible.
Since industrialization, human activities have disrupted the balance of GHGs in the earth's atmosphere, resulting in global climate change. The IPPC (Intergovernmental Panel on Climate Change) has published excellent reports on the topic. The most recent one has concluded that many natural systems are already impacted by regional climate change. The reports have also shown that there has been a significant increase of GHGs in the atmosphere and that 11 of the last 12 years have been the warmest on record since 1850.
The IPPC is a group of 600 scientists commissioned by the United Nations. Their reports are considered to be the most authoritative and exhaustively peer-reviewed among all the climate change study groups.

We can all help to slow global warming!
The gasoline we burn in our cars and electricity we use at home are major contributors to global warming. We can all help by cutting consumption and lowering our individual "carbon footprint" (the amount of carbon dioxide and other greenhouse gases produced by everything we do, including purchasing products). See the following sites for good tips on how you can help reduce your impact on global warming:
