I'm well aware of Russia's ability to defend itself. I'm also well aware of Europes sentiment of starting wars. The last two world wars have originated there.<p>A possible outcome of climate change is severe winters across all of Nothern Europe (severe as in Russian style -20). Without Russian supplies Europe's reserves and import terminals (Wales and Italy) would not be able to supply enough liquified natural gas to keep Europeans warm all winter.<p>Anyway, the point is that climate change can cause international tension and that was the reasoning for it being part of the death clock.
