Did Global Warming Save Hitler?

Adolf Hitler survived the assassination attempt of 20 July 1944. Why? Three pieces of evidence point the way:

From “The history of the German resistance, 1933-1945” by Peter Hoffmann, p655):

…the briefing conference was normally held in a bunker and…on 20 July only it was held in a flimsy hut owing to the heat

From Wikipedia:

Hitler would have been killed had any of the three other scenarios occurred:
* both bombs detonated;
* the meeting was held inside Hitler’s bunker;
* the briefcase was not moved.

From the IPCC AR4 WG-I SPM (*) p7

At continental, regional and ocean basin scales, numerous long-term changes in climate have been observed. These include changes in arctic temperatures and ice, widespread changes in precipitation amounts, ocean salinity, wind patterns and aspects of extreme weather including droughts, heavy precipitation, heat waves and the intensity of tropical cyclones..

A panel has been convened to examine the above. The conclusion is that it is more likely than not that evil Exxon has helped emit greenhouse gases for the one reason of keeping Hitler alive.
