At the fall meeting of the American Geophysical Union, some interesting findings are being presented: arctic permafrost stores rather huge quantities of carbon, and the activities of arctic ground squirrels are "hastening the release" of greenhouse gases there.
She concluded that squirrels were playing "a far more important role in this permafrost carbon cycle than we thought".
So now squirrels are causing global warming.
But that doesn't mean you're off the hook for it:
A new study published Monday in the Proceedings of the National Academy of Sciences finds some electric cars actually make the air dirtier than gasoline-powered vehicles. The study assumes the energy that powers electric cars is coming from coal, which would mean the cars contribute more to soot and smog, and worsen global warming more than gasoline-powered cars.
And that doesn't even take into account the environmental damages associated with battery production and disposal. So you EV owners can wipe that smug right off your faces.
Although, if you live in Oregon, you may catch a break - depending on where you live in the state, most of your power comes from natural gas and hydro; only 20% comes from the PGE-owned Boardman coal plant, and they plan to convert that to natural gas in the next 6 years.
