Which is more likely...

Global warming is science fiction on an industrial scale,it proposes a

planet's temperature within a certain range and anyone who opposes
this proposal is a science fiction denier.
So,what is the more likely -
A - That Western science has collapsed
B - That Western civilization is collapsing
C - That people are coming to their senses to prevent B from happening
through restoring common sense to A
There might not be any people left to answer the question.
Ocean acidification on track to be among the worst of the last 300 million years

The group also examined the several mass extinctions that defined the Mesozoic—the age of dinosaurs. The boundary between the Triassic and Jurassic included a large increase in atmospheric CO2 (adding as much as 1,300 to 2,400 ppm) over a relatively short period of time, perhaps just 20,000 years. The authors write, “A calcification crisis amongst hypercalcifying taxa is inferred for this period, with reefs and scleractinian corals experiencing a near-total collapse.” Again, though, it’s unclear how much of the catastrophe can be blamed on acidification rather than warming.
Finally, we come the big one—The Great Dying. The Permian-Triassic mass extinction (about 252 million years ago) wiped out around 96 percent of marine species. Still, the rate of CO2 released to the atmosphere that drove the dangerous climate change was 10-100 times slower than current emissions.
