No sugarcoating this reporting from Popular Mechanics:
What [Stefan] Rahmstorf, along with fellow co-author and U.S. statistician Grant Foster, discovered was that the world warmed an average rate of 0.35 degrees Celsius in the past decade, a significant increase from the 0.2 degrees Celsius increases typically recorded since 1970. This is obviously worrying, since not only is the planet warming, but the rate at which it’s warming may be accelerating, complicating the timeline for addressing the climate crisis.
Ouch.
The authors explain how they got to this point:
The new finding was made by stripping away natural influences, such as El Niño events, volcanic eruptions, and solar activity, to analyze the underlying rate of warming.
That said, this would further backstop James Hansen's late-2023 findings, viciously attacked by Michael Mann. It would further backstop Peter Brannen's new book.
Per both of them, we have a "good" chance of hitting 5°C within a century.
Is this too high?
PM notes that other scientists have found accelerated warming, but at "just" 0.27 degrees.
Do the math. That's 2.7°C in a century, plus the 1.5 currently, for a total of 4.2. (The 3.5 would get us to 5C.)
