Almost all experts studying the recent climate history of the earth agree now that human activities, mainly the release of heat-trapping gases from smokestacks, tailpipes, and burning forests, are probably the dominant force driving the trend. The gases add to the planet's natural greenhouse effect, allowing sunlight in, but preventing some of the resulting heat from radiating back to space.

Drawing on research on past climate shifts, observations of current conditions, and computer simulations, many climate experts say that without big curbs in greenhouse gas emissions, the 21st century could see temperatures rise 3 to 8 degrees, weather patterns sharply shift, ice sheets shrink and seas rise several feet.

What we do: Work to promote solutions to global warming using current and cutting-edge technology that will reduce our use of fossil fuels. By switching to energy efficient cars and trucks, and clean, renewable energy, we can curb global warming pollution, save consumers money and curtail our reliance on oil.

Global Warming Explained
After years of debate, a near consensus among the world's scientists has concluded that we are warming the planet, and unless we take steps now to curb global warming, our way of life, our planet, and our children are all in grave danger. But there is hope. Each us can make simple decisions that will reduce global warming pollution.
Network of activists and volunteers are dedicated to curbing global warming. They are working with churches, labor unions, mayors and state governments to bring about a cleaner, smarter energy future.
