The Beetle Problem August 3, 2011 : 2:47 PM

From the Climate Reality Blog:

“When we burn dirty sources of energy like coal and oil, we release carbon pollution into the atmosphere. Thankfully, some of the pollution is taken up by carbon “sinks” — ecosystems like oceans and grasslands that store carbon and temporarily keep it from warming the atmosphere.”

“A new study estimates that between 1990 and 2007, the world’s established forests stored about a third of the carbon from dirty fuels. But forests need to be healthy to hang onto their stored carbon, and a little beetle is posing a big challenge to forests in western North America.”
