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.
China is now the world's largest aircraft market, passing the US, so they could easily become the dominate manufacturer. To lure worldwide carriers, the state owned aircraft company has unlimited funds to develop and market deeply discounted aircraft of all sizes. From 1790 until 1980, the US spent money to develop its industries, what are the odds that will ever happen again?
