The Guardian points to something that everyone living in the DC area (and probably entire Eastern Seaboard) already suspected was the case:
Now scientists have confirmed what’s been pretty obvious: the entire world has just come through the warmest six months, the warmest year, and the warmest decade on record. Following the hottest June ever,AccuWeather.com yesterday said July was the second hottest July recorded – and the warmest ever for land temperatures alone.
And with that comes consequences:
Just in case those feel like abstractions, here’s what they mean in practice: because warmer air holds more water vapour than cold, deluge increases. Hence, Pakistan has seen the worst flooding in its history. Because heat cuts grain yields, Russia has stopped exporting grain, spiking prices. Greenland? Guess what – heat melts ice.
But hey, just regular weather cycles, right?
