Greenhouse Gases Reach Record High
From the Associated Press: The U.N. weather agency says the three main greenhouse gases in the Earth's atmosphere have reached new record highs. Apparently this is the first time in a decade that the concentration of methane in the atmosphere has increased, partially by natural sources, like wetlands, and partially by human activities such as fertilizer use or fuel combustion. Ugh.
