Climate Change: the Science is settled and also was “completely overturned” in mid-2024

We’ve been informed that, when it comes to climate change, “the Science [was] settled” as of no later than 2007 when Professor Dr. Al Gore, Ph.D. talked to fellow Scientists in the U.S. Congress (state-sponsored NPR). Science’s climate models generate accurate predictions of Earth’s future temperatures, storm patterns, hurricane frequency and track, etc. These models depend critically on submodels of ocean behavior. According to Scientists at the World Bank in 2022:

Oceans are the largest heat sink on the planet. They absorb 90% of the excess heat caused by climate change. Oceans are also a very efficient carbon sink, absorbing 23% of human-caused CO2 emissions.

Here’s some July 2024 news from MIT:

“By isolating the impact of this feedback, we see a fundamentally different relationship between ocean circulation and atmospheric carbon levels, with implications for the climate,” says study author Jonathan Lauderdale, a research scientist in MIT’s Department of Earth, Atmospheric, and Planetary Sciences. “What we thought is going on in the ocean is completely overturned.”

As it happens, “complete overturning” of what had been settled Science requires a higher level of panic:

Lauderdale says the findings show that “we can’t count on the ocean to store carbon in the deep ocean in response to future changes in circulation. We must be proactive in cutting emissions now, rather than relying on these natural processes to buy us time to mitigate climate change.”

“My work shows that we need to look more carefully at how ocean biology can affect the climate,” Lauderdale points out. “Some climate models predict a 30 percent slowdown in the ocean circulation due to melting ice sheets, particularly around Antarctica. This huge slowdown in overturning circulation could actually be a big problem: In addition to a host of other climate issues, not only would the ocean take up less anthropogenic CO2 from the atmosphere, but that could be amplified by a net outgassing of deep ocean carbon, leading to an unanticipated increase in atmospheric CO2 and unexpected further climate warming.”

Expected the unexpected, in other words, even when Science is settled. (Separately, with the Science having been settled prior to this “complete overturning”, why does the overturner refer to “some climate models” making a prediction and not others? With settled Science, shouldn’t all climate models agree on the major points, just as all models of orbital mechanics agree on when Halley’s Comet will return to our charred planet?)

    • Anon: That’s an upsetting map because it shows that Florida’s all-time high temp occurred in 2023! I wonder if there is some measurement bias, though. Florida probably didn’t have thermometers everywhere back in 1936 when LA and TX set their records.

    • Sorry for the upsetting map! Your observation on thermometers sounds correct. Florida was I think relatively undeveloped prior to the 1930s (Tamiami trail road opened in 1928 and prior to that the southwest coast was pretty much just mangroves and swamp).
