Temperature Changes

GHG Emissions Increase

• (^) Since pre-industrial times atmospheric concentrations of CO 2 , CH 4 and N 2 O have climbed by over 31%, 151% and 17%, respectively. Scientists have confirmed this is primarily due to human activity. Burning coal, oil and gas, and cutting down forests are largely responsible.

Emissions

Individual Emissions

• (^) In the United States, approximately 6. tons (almost 15,000 pounds carbon equivalent) of greenhouse gases are emitted per person every year. And emissions per person have increased about 3.4% between 1990 and 1997. Most of these emissions, about 82%, are from burning fossil fuels to generate electricity and power our cars.
