For climate disease, there is no doubt remaining about the diagnosis:  global overheating, mostly from an insulating blanket of the carbon dioxide produced by burning fossil fuels. That’s what stirs up such knock-on effects as extreme weather and expanding subtropical deserts.

It's now dishonest to claim that the overheating hypothesis fails, just because some line of evidence seems dubious to you. Even if you were right to be suspicious, there would still be 11 other independent lines of evidence , all firmly pointing at global warming destroying our favorable climate.

Anyone still dubious about global warming immediately labels themselves as either a quarter-century out of date or a profit-making promoter of climate confusion.

The climate scientists’ forecast is also impressive –so far as it goes. However, their state-of-the-art climate simulations leave out components where they are not “sure enough” about the numbers. Vicious-cycle feedback loops were originally omitted as insufficiently understood.

When only the slow accumulation of heat-trapping gases are included in simulations, it’s no surprise that they show the heat waves slowly getting worse.
