As for North America as a whole - perhaps warming in Canada and Mexico tips the balance, as for South America - I don't know.<br /><br />Hansen's study is global. In my last post I used part of figure 4, the legend of which states it's obtained using the local temperature anomalies divided by the local SD - this is done for the globe. Sorry, could have been clearer in the post.<br /><br />The Barriopedro figure above is for the average of the Europe area stated in the paper. Doing the same for the available global average temperature series would be trite as we can see visually GAT is already outside the range of natural variability.<br /><br />Actually looking at the distribution of red and brown patches in Hansen figure 3, and the trends of red (>2SD) and brown (<3SD) in figure 5, by the end of this decade virtually all of the globe should be showing significant increase in heatwaves.Chris Reynoldshttps://www.blogger.com/profile/16843133350978717556noreply@blogger.comtag:blogger.com,1999:blog-1367053740188758246.post-14758808740003058902011-11-21T07:26:12.257-08:002011-11-21T07:26:12.257-08:00Another good post. Until you mentioned that the to...Another good post. Until you mentioned that the top five hottest year were outside the ND I missed the real and somewhat frightening significance of the graph. <br /><br />Globally, most of the hottest years are all in the last decade or so. That being the case I don't think it would be amiss to conclude that Global temperatures will mirror the European example. Are you aware if a similar analysis has been done for global temps?Lazarushttps://www.blogger.com/profile/14139033650731770470noreply@blogger.com
