GregLaden writes: "Despite the fact that the US has been releasing less CO2 into the atmosphere in recent years, greenhouse gasses globally continue to increase in concentration. There are several reasons that these gasses continue to accumulate. Also, the US burns less fossil fuel these days owing to the recession, but exports more. And then there is methane, which is a less well understood problem."
"They that can give up essential liberty to obtain a little temporary
saftey deserve neither liberty not saftey."
