The amount of greenhouse gases released into the
atmosphere in the United States increased 1.4 percent
That's the conclusion of a report put out by the
U.S. Environmental Protection Agency tracking emissions
from 1990 to 2007.
The agency said the rise in the amount of heat-trapping
gases stemmed from increased burning of fossil fuels
and electricity use.
Overall, the amount of carbon dioxide released from
direct human causes jumped more than 20 percent from
1990 to 2007, the report said.
