The physical evidence for g****l w*****g is not refuted. CO2 is not the only heat trapping gas. Consider methane CH4, for example. As global temperatures rise the frozen reaches of Alaska melt and release methane. We have worldwide disappearing of glaciers, rising sea levels, loss of Artic sea ice, calving of Antartic glaciars, increasing high seas pH levels leading to coral reef die off. The list can go on and on and on. His initial point of small numbers, of course, appeals to some, but we are talking about the thermodynamic shifting of equilibria of physical systems. I do have some quibbles with the popular model that greenhouse gases reflect heat back to the surface. I think that model is not correct.

All of which is why there are few actual warming deniers. C*****e c****e is a constant.
The problem remains, though, that connecting that change with man's actions is very hard to do, and so far, any "evidence" is clouded by the hyperbole of the true believers.
What was threatened/predicted hasn't happened, making more skeptics all the time. Computer models have proven to be only models of scenarios that have not happened.
There have been ice ages in the past, with subsequent warming periods, which climatologists can't explain. But
THIS TIME, we are told, they know exactly what's happening. Except they can't quite explain why it's not happening the way they said it would.
Well, a lot of us know why: Because they don't know.
Maybe it's anthropogenic, maybe it's not. While it sounds good that it may be, in some part, the t***h, the problem remains that the "solution" will cost many trillion$, and will, at the best projections (by those who are pushing for the spending to reduce C)2 emissions) are that it would slow down the warming by a very small percentage.
IOW, we're doomed either way, by their own words.
Of course, we're not doomed at all. While the prophecies are for a greta rise in sea levels, there is no work going on here to actually prepare for that rise.
Why is that?
