OK, I base my thoughts on visible, real conditions. These are not instrument readings over time
The Glaciers in Glacier National Park have been receding for some time now. I have hiked there and seen the recession.
In the Exit Glacier National Park in Alaska, as you approach the glacier, at least two miles out, there is a sign designating the location of the toe of the glacier in 1896. There are other signs along the way locating the glacial toe in specific years.
What that means is that the US Government has known of the warming trend for a very long time, perhaps 100 + years.
The ice is gone. It Melted. It was warmer.
The climate has changed from accumulating glacial ice to melting glacial ice. Perhaps on a really long term view, the noted results are a continuation of the change that ended the last ice age. Perhaps not.
So, is the present condition the result of prolonged weather change in Montana and Alaska. Yes of course. Is that permanent climate change? Perhaps.
However, all that is irrelevant to the political question at hand. Was the warming in Montana and Alaska in 1896 the result of excess atmospheric carbon dioxide resulting from SUV’s, jet airplanes and coal burning power plants? No, of course not
The way to end the Climate Change political controversy is to eradicate the enemies of the world population perpetrating the hoax. Such misguided people are the only real problem
Thanks for the reply.
My professional training revolved around making measurements, and usually small measurements. So that’s the way I tend to first think of things.
I found your comments about glaciers to be very interesting. A glacial retreat of two miles is certainly well beyond any estimate of uncertainty!
I suppose the real crime here is that no one is allowed to debate the issue. As you noted, it’s become too political. A professor who wants to argue for man-made global warming would talk to a full house. A professor who wants to argue against man-made global warming would be shouted down, and maybe even physically attacked. That’s surely not how science is supposed to work.
