    What is the atmospheric pressure in terms of psia at an altitude of 60 miles ?? How is this related to the density of the atmosphere at that altitude ?? Why would a change in atmospheric pressure of 3% of ~ 2 X 10 exp (-5) psia have any effect on the average temperature of the globe ??

    That's why I explained this in my OP. I said that for a time, as the ice sheet melts in the North, you would expect air currents flowing across it and down South to cool the southern areas just like if you had a chunk of ice melting on a hot kitchen counter with a fan behind it. You would feel cooler in that kitchen until the ice reached a crucial smaller size where it no longer could affect you. Then from then on you'd roast. The temporary cooler Summers follow the law of the specific heat of the water molecule. That law says that water as it changes phase from solid to liquid & liquid to gas (steam) draws in a large amount of heat energy in order to do so. In other words, water in its different forms has an extremely stabilizing effect on our planet. The ice sheets literally act like air conditioners. The oceans literally act like huge environmental temperature stabilizers. But when you suddenly get a thinning insulation in the outer atmosphere allowing in too much solar radiation in the Summers, and the ice sheets & permafrost begin to melt, you destabilize the weather and the type of havoc we've been seeing with 100 year storms happening every other year...unusually cooler Summers, then really hot ones...then cool ones again...harsh Winters...all are indications that our climate is getting whacked and our ice/ocean ratio is being upset and not in a good way.

    With the thinning thermosphere we have (generally) hotter Summers and reliably colder Winters. Just like if you had a tar paper shack with thinning insulation. It would be more exposed to the extremes without protection in both seasons. When our "ice chunk on the kitchen counter" (polar ice sheets) reach a crucial smaller size, you can expect reliably hotter Summers (possibly unbearably hot) and reliably colder Winters, as our thermosphere continues to thin.

    I'd suggest actually reading the article that you linked to. And reading the OP.

    To answer the question in the thread title

    What (*)(*)(*)(*)ing part of "average" " global" temperature is difficult to understand?

    Just because you had one cold day in Kansas does not mean all of Australia has not had heat waves

    What part of "science disagrees" did you not get?

    They say it is thinning.

    I don't know.

    Why do you feel that these questions are relevant to my point? Do the answers to these questions somehow disprove that the thermosphere is thinning? Please explain. Because if you think that they do ... then real science disagrees with you.

    It is pretty simple. When you get used to warmer temperatures your body adjusts. Then when the temperatures drop it seems colder. We always called it being climatized. My first summer in Alabama was like living in hell.

    Look it up - I've provided the link. Then review the OP and the claim of a thinner atmosphere.

    It isn't that cold in Kansas. The polar vortex is gone. It didn't get that cold.

    Apologies to everyone - got testy and was ultra tired after a long long day at work

    But I have to admit I am "over" denialists telling me that because there is still some snow somewhere then global warming is a hoax

    I'm not mad at ya. But we are going to get another winter storm coming next week. So be prepared for more nonsense. It will snow in New York most likely.

    That is not an answer. Were my questions not clear?

    My winter doesn't feel colder. We had rain on Christmas, and it was unseasonably warm all through November and into early December as well. What we seem to have is more extremes, more wild fluctuations, during the winter, at least in my part of the country.

    You can answer your own questions by reviewing the OP and understanding the point that was made about a thinning atmosphere.

    Of couse, climate change is real. The climate has been changing forever. Sometimes it's warm, somtimes it's cold. Sometimes it's wet and sometimes it's dry. Duh.

    The next pole shift might reset things, though. At least on Earth anyway. That oughtta be a hoot.

    Rare coast-to-coast cold snap to engulf Lower 48 late next week

    Temperatures 30 to 50 degrees colder than normal, the cold snap will be most remarkable for the vast amount of the country it is predicted to cover.

    Cliff Mass, an atmospheric science professor, wrote that the cold snap could be “far colder than we have seen in many years. ”

    http://cliffmass.blogspot.com/2016/12/the-potential-for-major-cold-spell-in.html

    Matt Rogers, a meteorologist with Commodity Weather Group, said it takes a rare jet stream to deliver cold air to both coasts simultaneously. “Typical jet stream wavelengths are too narrow to allow cold outbreaks to reach coast-to-coast nearly simultaneously,” he said. “The width of this upper level trough pattern is impressively large.”
