The climate change movement: July 28, 1995 to August 14, 2020 RIP

[redpoint5]

I like Julia and Denzel, but the movie is rated 6.6, which is usually below the threshold for what I'll try. 7+ is a good threshold for me, with a 6.8 around the lowest rating I sometimes enjoy.

Mayhap someone will stop by and explain the connection to coral bleaching.

Anyone know if @cRiPpLe_rOoStEr can swim? Kinda really wet down that way according to the international news i watch

I'll watch it despite the idiotic quote.

In the screenplay, it's what the White House had to say about the PBS 'FRONTLINE' episode which shined a light where the oil industry and it's cronies would rather have had it remain unilluminated.
FRONTLINE has a reputation for extreme vetting of the information it shares, and an unimpeachable reputation within the realm of investigative journalism. It was spot-on for John Grisham to weave it into the narrative.

Corals evolved to survive within only a very narrow temperature window. About 90% of all the heat from global warming ends up in the oceans. They've warmed enough to constitute 'oceans' in which coral did not evolve for. It's that simple.

Corals evolved to survive within only a very narrow temperature window.

I picked only one paper to scan, so this is cherry-picking, but:

Scleractinia stands out as one of the few orders of calcified metazoans that arose in Triassic time, long after a greater proliferation of calcified metazoan orders in the Paleozoic. The origin of this coral group, so important in reefs of today, has remained an unsolved problem in paleontology. The idea that Scleractinia evolved from older Paleozoic rugose corals that somehow survived the Permian mass extinction persists among some schools of thought. Paleozoic scleractiniamorphs also have been presented as possible ancestors. The paleontological record shows the first appearance of fossils currently classified within the order Scleractinia to be in the Middle Triassic. These earliest Scleractinia provide a picture of unexpectedly robust taxonomic diversity and high colony integration. Results from molecular biology support a polyphyletic evolution for living Scleractinia and the molecular clock, calibrated against the fossil record, suggests that two major groups of ancestors could extend back to late Paleozoic time. The idea that Scleractinia were derived from soft-bodied, “anemone-like” ancestors that survived the Permian mass extinction, has become a widely considered hypothesis.

The evolution of modern corals and their early history

Reconstruction of the past 5 million years of climate history, based on oxygen isotope fractionation in deep sea sediment cores (serving as a proxy for the total global mass of glacial ice sheets), fitted to a model of orbital forcing (Lisiecki and Raymo 2005)[2] and to the temperature scale derived from Vostok ice cores following Petit et al. (1999).[3]

It appears that coral revert to a soft-bodied form at times, and the reef is actually built by algae in the coral's epidermis.

Apparently... from a 10 minute investigation...

(the term aragonitic biomineralization reminds me of an old inactive forum member)

The dooms day climate cult are more afraid of nuclear power than climate change.

The dooms day climate cult...

Who are those people anyway? I just listened to The Anthropology of Karens. I suspect they're on a power trip, not genuinely concerned.

The coral provides the calcium carbonate scaffold on which the algae populate.
The algae give coral its color.
During a bleaching event, the algae are expelled, and we have only 'limestone' to look at.
If a second bleaching event arrives before the coral can recover from the former ( which is now being observed ), it's likely that the coral will be lost, and 25% of the marine 'food chain' which depends upon it, lost along with it.
