[NEWS] Oops, Scientists May Have Miscalculated Our Global Warming Timeline

#1

Whatever your stance is on climate change (it’s real, let’s move on), 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 new paper from the University Western Australia Oceans Institute has some bad news: the world might’ve blown past that threshold four 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.

By analyzing strontium to calcium ratios in these sponges, the team could effectively calculate water temperatures dating back to 1700. The sponges watery home in the Caribbean is also a plus, as major ocean currents don’t muck up or distort temperature readings. This data could be particularly useful,as direct human measurement of sea temperature only dates back to roughly 1850, when sailors dipped buckets into the ocean. That”s why the Intergovernmental Panel on Climate Change (IPCC) uses 1850 and 1900 as its preindustrial baseline, according to the website Grist.

“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.”

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.

Unfortunately, even if the sponges are wrong, there’s mounting evidence that we are in the process of crossing that 1.5 degree threshold as we speak. This January was the hottest on record, clocking in at 1.7 degrees above pre-industrial temperatures. According to New Scientist, that means we’ve been above 1.5 degrees of change for at least a year. That doesn’t jump the long-term average over the 1.5-line, but it’s certainly a sign we’re getting close fast.

Regardless of the percentage, one thing is certain—climate change is an all-hands-on-deck crisis. In order to save the planet for future habitability, humans need to curtail emissions immediately—after all, the sea sponges are telling us so.

tacamateurs remember me saying? i went into the almanac! there were heatwaves around 1900! i think they were even in the 1800's!!! also i said that changing the level could harm or even freeze things or something else extreme... they are admitting 80 years but it was further back when i researched it....

Get a life instead of jumping on every conspiracy theory you can find

I cant even be bothered to read it

when it's damning i bet you can't.... when the warming started over 80 years ago.... :shock: :shock: :shock: when the roads had horses

Just more conspiracy bullshit !
the sea sponges in the caves... like tree rings tell the story.... now some scientist won't go with that data.... they sound like you! :lol: :lol: :lol:

Youve not researched anything !!

All you've done is spent hours online trying to find something that backs up your conspiracy theory. Thats NOT RESEARCH. Research is considering ALL the evidence and the overwhelming evidence points to global warming being the result of man made carbon emissions !!

Not going to argue anymore because you simply discount all the evidence like you always do

Thats the end of it.. Im done

you don't even listen.... go in an almanac and look!!!! :shock: :o the data is there on heatwaves..... case closed... go back to denying data.... like you told me!

Thew people who believe in climate change are those who do not will never agree on what causes it.

Everybody know what causes global warming. There are thousands upon thousands of reports from people like NASA, European Space Agency, United Nations, National Oceanagraphic Institute, Hardvard University etc etc and they ALL agree that climate change is a consequence of mans increasing use of fossil fules

As ever, Brassy has IGNORED all of those reports and simply cherry picked a single report that appears to support his conspiracy theory. And even that report admits :-

"it begs credulity to claim that the instrumental record is wrong based on paleosponges from one region of the world"

If you are going to research global warming, THEN RESEARCH IT. Dont simply ignore everything that you dont happen to agree with !
