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.
