Bummer: Climate Doom Happened Six Years Ago Or Something

I guess we’re all dead

Oops, Scientists May Have Miscalculated Our Global Warming Timeline

Whatever your stance is on climate change (it’s real!), it’s impossible to have missed the near-ubiquitous call to action to “keep temperatures from exceeding 1.5 degrees Celsius compared to pre-industrial levels.” Over the past few years, the somewhat bureaucratic phrase has become a rallying cry for the climate conscious.

This ambitious target first surfaced following the Paris Climate Agreement, and describes a sort of climate threshold—if we pass a long-term average increase in temperature of 1.5 degrees Celsius, and hold at those levels for several years, we’re going to do some serious damage to ourselves and our environment.

Well, a paper from the University Western Australia Oceans Institute has some bad news: the world might’ve blown past that threshold six years ago.

Published in the journal Nature Climate Change, the paper reaches this conclusion via an unlikely route—analyzing six sclerosponges, a kind of sea sponge that clings to underwater caves in the ocean. These sponges are commonly studied by climate scientists and are referred to as “natural archives” because they grow so slowly. Like, a-fraction-of-a-millimeter-a-year slow. This essentially allows them to lock away climate data in their limestone skeletons, not entirely unlike tree rings or ice cores.

Oh, good, 6 sea sponges studied means climate doom 6 years ago.

“The big picture is that the global warming clock for emissions reductions to minimize the risk of dangerous climate change has been brought forward by at least a decade,” Malcolm McCulloch, lead author of the study, told the Associated Press. “Basically, time’s running out.”

LOL. Cult.

The study concludes that the world started warming roughly 80 years before the IPCC’s estimates, and that we already surpassed 1.7 degrees Celsius in 2020. That’s a big “woah, if true” moment, but some scientists are skeptical. One such scientist, speaking with LiveScience, said that “it begs credulity to claim that the instrumental record is wrong based on paleosponges from one region of the world … It honestly doesn’t make any sense to me.” Other experts expressed wanting to see more data before completely upending the IPCC’s climate goalposts, which say the Earth is currently hovering at a long-term temperature change of around 1.2 degrees Celsius.

None of it makes sense, because this is all ravings of a doomsday cult.
