ANDREW KLEKOCIUK: This one's actually appeared for a period of about four hours. It's incredibly cold up there during the summer time. Temperatures are about minus 150 degrees. And that enables water vapor to freeze into tiny ice crystals.
That makes these special clouds perfect as natural, high altitude thermometers; and the results they've provided are interesting to say the least.
According to these researchers, despite the lower atmosphere warming by less than one degree over the last few decades, the upper atmosphere has cooled by ten!
And that means more noctilucent clouds are appearing in more places.
Making these amazing clouds a breathtaking, but worrying symbol of climate change.
Please note that the bold bit was not said by the scientist, but by the host of the program.
How interesting. This is a kid's show, Behind The News, on ABC. This give the impression that AGW/CC (which is brainwash speak for earth is heating to hell and it's all our fault), is proven somehow by noctilucent clouds. How is that?
