So this scare article has a decent enough tag line; "Proof the Climate is changing". I noted though that there is one line saying that "The more methane released, the more water vapor is up there" but it is not substantiated. They also say they were first seen after Krakatoa went up in 1885. They infer some direct relationship, yet it also is not substantiated. Then they just had to add some little tidbits of "possibly due to climate change" read: Haven't got the foggiest clue but had to put that in for political purposes so we can keep our grant" or some such. Bottom line, these are really cool looking as the sun reflects off them after dark due to angle of attack and their height. I still would prefer the Aurora coming south.....
