Even if this were true, which it isn’t, or at least it is not proven, we better get used to a warmer climate, take the good things it brings and deal with any problems like we always have. Because we can’t do anything to prevent warming of the magnitude they predict, and even if we earth dwellers could, we absolutely won’t. All these warnings are a practical waste of time.
I spend summers in southern Oregon, growing tomatoes and grapes, and such. We have a 9500 foot peak, Mt. McLaughlin in our neighborhood. In 2015 and 2016 the snow on the peak disappeared in June. In 2015 the snow re-appeared in mid-November and in 2016 it was early November. In 2017 the snow cover persisted until mid-July and re-appeared in mid-October.
I understand that this is WEATHER and not CLIMATE, but inflection points can be both. For a few years, grape growers ripened Mourvedre (a late varietal). This year, not so much.
There are other factors (warm Humboldt current, etc). But regardless, trends go in one direction until they don’t. The Earth’s climate is part of a non-linear, coupled, chaotic system which cannot be modeled using our current level of mathematical and computing sophistication. The magnitude of their predictions is essentially hollow.
I also agree that we can’t do a lot about preventing warming (or cooling). What we can do is continue trying to understand the system, hopefully with a little less shrill alarmism.
