Increase of Global CO2 Emissions Alarming

USA Today reported today on a recent study by Carnegie Institution's Department of Global Ecology that during the 1990's, emissions of carbon dioxide rose about 1.3% per year. But the rate of emissions after 2000 increased to 3.3% per year.

The growing global economy is fueling an increase in fossil fuels burned and an increase in the manufacturing of cement, both of which contribute to rising carbon emissions. In 2000, 7 billion metric tons of carbon were released into the atmosphere. By 2006 emissions had increased by 8.4 billion metric tons.

Researchers now believe that the Earth's plants, oceans and land can no longer naturally absorb the excess carbon, causing a build-up of CO2 in the atmosphere and increasing the effect of global warming.
