Skeptical Science has been really pulling out all the stops as 2010 comes to an end, first releasing a great PDF Guide to Global Warming Skepticism and now adding the above image summarizing all the different indicators that the world is indeed warming. Not included in the graphic, Skeptical Science points out, are several other indicators: Lake and rive ice cover freezing later and breaking up earlier, permafrost warming at greater depths, lakes warming, growing seasons lengthening.
The original post has links to research for all those not-included indicators as well as other file formats of the Creative Commons-licensed graphic, including vector-based ones should you need to do some serous scaling of it: Skeptical Science
