The world won’t stay below 1.5C of warming, largely because we’re already there.

“We now expect a 3C world,” states a March analysis by Morgan Stanley. This level of global heating above preindustrial times is well beyond the 2C limit agreed to by governments and would lead to catastrophic heatwaves, floods, economic strife and other upheavals.

The climate crisis is on track to destroy capitalism, a top insurer has warned, with the vast cost of extreme weather impacts leaving the financial sector unable to operate.

The world is fast approaching temperature levels where insurers will no longer be able to offer cover for many climate risks, said Günther Thallinger, on the board of Allianz SE, one of the world’s biggest insurance companies. He said that without insurance, which is already being pulled in some places, many other financial services become unviable, from mortgages to investments.

Economic models have systematically underestimated how global heating will affect people’s wealth, according to a new study that finds 4C warming will make the average person 40% poorer – an almost four-fold increase on some estimates.

Just finished the REVENGE of the TIPPING POINT by Macolm Gladwell. It's really interesting in the context of our current political climate but also around things as facetious as Linux on the Desktop or Artificial intelligence. It's hard to observe and participate in some of these group-think related tipping points while also trying to be introspective without feeling as if you are part of the problem. Or worse, becoming apathetic or putting your hands over your ears and pretending everything is fine.

His end quote has rung a bell in me however, "The tools necessary to control an epidemic are sitting on the table, right in front of us. We can let the unscrupulous take them. Or we can pick them up ourselves, and use them to build a better world". Sometimes, those of us with the abilities or talent or voice just need someone to remind us it seems.

Tipping points are fabricated, engineered, built and that's OUR lane.

We're seeing fewer decent-paid jobs and the need for universal basic income as we install more machines that replace former high-level work

Normally, two-thirds of sea level rise is due to melting ice from mountain glaciers and Greenland and Antarctic ice caps, and one-third from the thermal expansion of the oceans.

Last year, the hottest year on record, this was reversed, with warmer water accounting for two-thirds of the sea level rise of 0.59cm (0.23in) – considerably more than the 0.43cm scientists were expecting.

Taking strong action to tackle the climate crisis will increase countries’ economic growth, rather than damage their finances as critics of net zero policies have claimed, research from the world’s economic watchdog has found.

Retreating glaciers threaten the food and water supply of 2 billion people around the world, the UN has warned, as current “unprecedented” rates of melting will have unpredictable consequences.

Do you think, Earth's system has elements that have a tipping point, a threshold from when on they unstoppably glide into a completely different, then-stable state?

Computer simulations show nightmare Atlantic current shutdown less likely this century

If the #AMOC weakens but not fully collapses, many of the same impacts—including crop losses and changes in fish stock—likely will still happen, but not the big headline one of Europe going into a deep freeze, Baker said.

Scientists measure the AMOC strength in a unit called Sverdrups. The AMOC is now around 17 #Sverdrups, down two from about 2004 with a trend of about 0.8 decline per decade, scientists said.

One of the debates in the scientific world is the definition of an AMOC shutdown. Baker uses zero, but other scientists who have been warning about the shutdown implications, use about 5 Sverdrups. Three of Baker's 34 computer models went below 5 Sverdrups, but not to zero.

That's why Levke Caesar and Stefan Rahmstorf, physicists at the Potsdam Institute for Climate Research and authors of an alarming 2018 study about potential shutdown, said this new work doesn't contradict theirs. It's more a matter of definitions.

"An AMOC collapse does not have to mean 0 (Sverdrups) overturning and even if you would want to follow that definition one has to say that such a strong AMOC weakening comes with a lot (of) impacts," Caesar wrote in an email. "The models show a severe AMOC weakening that would come with severe consequences."

Catching up with some recorded quizzing from today and on #TippingPoint there's a bloke from Leigh who's wearing a rather snazzy leopard print jacket. Wild stab in the dark here, but he might just be a #RugbyLeague fan.

"The Arctic region has been a massive store of carbon for thousands of years. Now it's warming between 3 and 7 times faster than the global average and that carbon is escaping into our atmosphere."

Is the Amazon region more resilient than assumed? A study shows that regional mean annual precipitation isn’t going to change much even if the region were completely deforested. This is contrary to previous findings that beyond a threshold, it would reach a #tippingpoint & turn into a savannah. Using a global storm-resolving model, #MPIM scientists A. Yoon & C. Hohenegger show: the loss of moisture created by plants is compensated by a large-scale atmospheric feedback.1/2

Two-thirds of the Earth’s surface experienced record heat in 2024. In oceans and on land, from the north to the south pole, records were smashed for the monthly average temperature. See where and by how much.

We are firmly in the post-climate change world now, and the serious implications of this demand honest acknowledgment. The reality is that we are living now in a time of continual disasters that are unfolding alongside our slower, planetary scale disaster.
