Hah! who says global warming isn't occurring, speak up?

Is it, Isn't it? should I care and can i do anything to slow it down? Its not the normal topic of what I blog about but I just had to put this up; NASA study confirms 2010 is the hottest year on record?

Unlike the politico's who like to deny there is any change and pointing to the cold Northern Hemisphere winter as proof, I would like to think that a NASA study is more accurate.
