According to the rocket scientists at NASA (and I mean that in the good way), we are at a point in climate change due to global warming that they were predicting in the '80s we wouldn't reach until the end of the 21st century. Not only that, but a phenomenon has developed that they didn't foresee.
Unusual weather events like extreme drought (think Dust Bowl in the '30s, 500 year floods) things that used to be rare, events only occurring 1 in a 1000 times, these extreme weather events are now happening 1 out of 10 times. The odds are that as more heat becomes available to drive these weather patterns, this will only get worse.
People who like to think of the US as number one in all things might take note of the Commercial Aircraft Corporation of China (Comac). They are poised to begin direct competition with Boeing and Airbus in 2016 with their version of the 737, and larger planes are already being developed.
