Excerpt from this story from EcoWatch:

Current climate policies are putting the world at a high risk of critical Earth system components reaching tipping points, even if global temperatures return to less than 1.5 degrees Celsius above the pre-industrial average following a period of overshoot.

However, a new study has found that, if global heating is quickly reversed, these risks could be minimized.

The human-caused climate crisis has the potential to cause a destabilization of large-scale elements of Earth systems like ocean circulation patterns, ice sheets and components of the global biosphere. In the study, the researchers examined the risks that future emissions scenarios and current mitigation levels posed to four interconnected tipping elements, a press release from the International Institute for Applied Systems Analysis (IIASA) said.

The research team determined the risks of tipping for destabilizing a minimum of one of four central climate elements: the West Antarctic Ice Sheet, the Greenland Ice Sheet, the Amazon Rainforest and the Atlantic Meridional Overturning Circulation (AMOC) — the Atlantic Ocean’s main ocean current system. All four of these contribute to the regulation of the stability of the planet’s climate. Sudden changes to these biophysical systems can be triggered by global heating, leading to irreversible outcomes.

The report’s analysis explains how important it is to stick to the climate targets laid out in the Paris Agreement, while emphasizing that our current choices will impact the planet for centuries or even millennia.

“Our results show that to effectively limit tipping risks over the coming centuries and beyond, we must achieve and maintain net-zero greenhouse gas emissions. Following current policies this century would commit us to a high tipping risk of 45% by 2300, even if temperatures are brought back to below 1.5°C after a period of overshoot,” said Tessa Möller, co-lead author of the study and a researcher with the Potsdam Institute for Climate Impact Research (PIK)’s Integrated Climate Impacts Research Group, in the press release.

The researchers discovered that tipping risks become substantial by 2300 for several of the future emissions scenarios they assessed. If the average global temperature does not return to less than 1.5 degrees Celsius by 2100 — even if net-zero greenhouse gas emissions are reached — there will be a tipping risk of as much as 24 percent by 2300. This means that in roughly one-quarter of the scenarios that do not return to less than 1.5 degrees Celsius by the end of the century, a minimum of one of the tipping elements they considered will have tipped.

“We see an increase in tipping risk with every tenth of a degree of overshoot above 1.5°C. If we were to also surpass 2°C of global warming, tipping risks would escalate even more rapidly. This is very concerning as scenarios that follow currently implemented climate policies are estimated to result in about 2.6°C global warming by the end of this century,” said co-lead author Annika Ernest Högner, also with PIK, in the press release.

“Only a swift warming reversal after overshoot can effectively limit tipping risks. This requires achieving at least net-zero greenhouse gases. Our study underscores that this global mitigation objective, enshrined in Article 4 of the Paris Agreement, is vital for planetary stability,” said Carl Schleussner, one of the authors of the study and a leader with the IIASA Integrated Climate Impacts Research Group, in the press release.

"Global warming is a hoax."

And what motive would someone have to create a hoax like that?

If you tell people the planet is getting hotter, many people will say things like "good, I'm freezing" or "yay, more fun at the beach". Or maybe they'll just move to a place that's cooler if it ever gets too hot where they are.

Sure, the world will eventually be too hot for us to survive, but the global temperature is only increasing by 1°F every 30 years. It will take centuries for that to have a noticeable effect.

Understanding what global warming is and why it's bad requires effort and analysis. There'd be no motive for a hoax like that. A hoax would usually create a much more urgent demand. A hoax would usually be easier to understand in order to manipulate the most people. A hoax would usually involve telling people what they already want to believe.

The Paris Climate Accords in 2015 set an ambitious (and necessary) goal of keeping global temperatures at 1.5 degrees Celsius above pre-industrial temps. But a new study says we might’ve blown past that threshold several years ago.

A new study from University Western Australia Oceans Institute studied long-lived Caribbean sclerosponges and created an ocean temperature timeline dating back to the 1700s.

While the study claims that we surpassed 1.5 degrees Celsius in 2020, other scientists question if data from just one part of the world is enough to capture the immense thermal complexity of our oceans.

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.
