According to the researchers, most tipping-point studies build the math in their models to focus on one predominant driver of collapse, for example deforestation in the Amazon rainforest. However, ecosystems aren't contending with just one problem but rather a swarm of destabilizing factors that compound one another. For example, the Amazon also faces rising temperatures, soil degradation, water pollution and water stress.

To investigate how these elements interact and whether these interactions can, in fact, hasten a system's demise, the scientists behind the new study built computer models of two lake and two forest ecosystems (including one which modeled the collapse of civilization on Easter Island) and ran them more than 70,000 times while adjusting the variables throughout.

Our main finding from four ecological models was that ecosystems could collapse 30-80% earlier depending on the nature of additional stress," co-author John Dearing, a professor of physical geography at Southampton University in the U.K. told Live Science in an email. "So if previous tipping points were forecast for 2100 (i.e. 77 years from now) we are suggesting these could happen 23 to 62 years earlier depending on the nature of the stresses."

Additionally, the IPCC calculations focused solely on the impact of technology choices on the climate, disregarding uncertainties in climate models, the relationship between climate and economic growth, population trends, and policy measures. “The significant contribution of our research is enabling policymakers to make informed decisions on climate action while fully understanding the existing uncertainties,” explains co-author Brian Ó Gallachóir from University College Cork.

The Earth Energy Imbalance from NASA satellite data broke through 1.8 W/m² (12-month mean)!

This is faster than I expeced.
More than many experts thought possible.

I called this the most important graph in the world.

A lot more heat is accumulating!

k roli so2 v klima ystemu

Sulphur particles contained in ships’ exhaust fumes have been counteracting some of the warming coming from greenhouse gases. But lowering the sulphur content of marine fuel has weakened the masking effect, effectively giving a boost to warming.

Some researchers have proposed that the drop in SO2 as a result of the IMO’s clean air regulations could be behind a recent spike in global sea surface temperature.

Carbon Brief analysis shows that the likely side-effect of the 2020 regulations to cut air pollution from shipping is to increase global temperatures by around 0.05C by 2050. This is equivalent to approximately two additional years of emissions.

While this will contribute to warming and make it even more difficult to avoid exceeding 1.5C in the coming decades, a number of other factors are likely contributing to the ocean heatwave.

These include a massive eruption of an underwater volcano in the south Pacific, an unusual absence of Saharan dust and a growing El Niño.

Thousands of tonnes of rock break off summit of Austrian mountain | Austria | The Guardian
https://www.theguardian.com/world/2023/jun/13/thousands-of-tonnes-of-rock-break-off-summit-of-austrian-mountain

“Hundreds of metres of the summit have simply broken off,” Christian Walter, head of mountain rescue for the Austrian region of Galtür, told local media.

Geologists told the Austrian news agency APA that the rockfall, which had been predicted for some time, had taken away part of the southern summit, including the crucifix typically found on mountain peaks in the region. They blamed melting glaciers as well as the thawing of permafrost due to the climate crisis for the collapse, which occurred on Sunday and was captured on film by mountain rescuers training in the region.

As Beijing swelters, activists hope the heat will prompt climate action | China | The Guardian
https://www.theguardian.com/world/2023/jun/30/as-beijing-swelters-activists-hope-the-heat-will-prompt-climate-action

although there is some limited education about climate change, permitted discourse stops short of talking about major policy shifts, such as reducing China’s coal emissions more rapidly. The government has pledged to become carbon neutral by 2060, but concerns about energy security and the need for economic growth mean that local authorities are showing no sign of backing down on building new coal power.

Also, says Zhao, “even if people link heatwaves and climate change, they don’t think it’s something that the individual should pay attention to.” Most people see it as being the government’s responsibility – and therefore out of the hands of the public, she says.

Still, awareness of climate change, and discussion about how it can be managed, is ticking up. The topic is increasingly discussed in state media. Analysis by Sixth Tone, a state-backed outlet, found that mentions of key words relating to climate change jumped from about 750,000 in 2019 to nearly 3.3m in 2021.

Surveys suggest that, compared with the US, a slightly higher proportion of Chinese people accept that climate change is happening and that it is caused by human activity.

Nitrogen compound emissions are a big matter in this small, packed country, becoming the dominant political issue over the course of a four-year crisis. Among other impacts, the crisis has hampered crucial housebuilding, because builders need nitrogen permits from a limited supply to cover construction emissions. The crisis has polarised social opinion, spurring the rise of a new rural populist movement and mobilising environmentalists who are desperately concerned about the state of wild habitats.

Soil Grown Tall: The Epic Saga of Life from Earth | SpringerLink
https://link.springer.com/book/10.1007/978-3-030-88739-1

"Soil Grown Tall" looks at the role of life in buffering the global carbon cycle, using evidence captured in paleosoils - fossil soils - over periods stretching back right to the beginning of the solar system..

Gregory is a pretty rare creature - a geologist and paelobiologist specialised in paleosoils, which he has analysed and studied way more than anyone else. He's always expressed surprise at how few colleagues made paleosoils their life's calling and, reading this masterpiece, you cannot but agree with him. More knowledge about our planet's history is hidden in fossil soils than anywhere else.

Retallack shows how paleosoils contain plenty of evidence towards what he calls the Proserpina Principle, or the way the planet achieved homeostasis - long-term stability - without falling either into a runaway greenhouse, like Venus, or an unchanging snowball, like Mars. The secret? A never-ending evolutionary arms race between producers (plants) and consumers (animals).

For example, when trees evolved they precipitated a serious ice age, as lignin is so, so hard to digest. When termites evolved the ability to digest wood a hundred million years later or so, they tipped the planet into a greenhouse world, as they put all the carbon trees had captured back in the air.

Similar producer-precipitated ice ages came earlier (with the evolution of lichens) and later (with the evolution of grasses), interrupted by consumer-precipated greenhouse worlds.

That dance goes back to the very dawn of life: the microbial mats that covered the world three thousand million years ago also drew down vast amounts of carbon dioxide, both directly through photosynthesis, and by enhancing weathering through the acids they produced. They, as much as lichens and trees, were responsible for planetary deep freezes.

The Proserpina Principle kept the planet liveable through mile-wide asteroid impacts and continent-sized volcanic eruptions (see the Siberian or Deccan traps). The huge amounts of carbon that spewed into the air heated the world up, which encouraged plant growth even into polar regions, which soon drew that carbon back into seas and soils.

What this long view leaves you with is, first, that as far as the planet is concerned, we're just the latest consumers tipping the world into a greenhouse (two hundred million years before termites, millipedes did a great job too), and second, that whether we fine-tune the system to keep Holocene-like stability (through all our favourite nature-based solutions, from agroforestry and holistic grazing to ocean iron fertilization and kelp forests) or not, matters little to the world: a hotter one will see less ice and deserts and more forests and grasslands, and they'll do the job of getting carbon back out of the atmosphere whether we like it or not.

Of course, something that matters little to the world may still matter a lot to us. Sea levels 90m higher and crocodile-infested rainforests in Antarctica may be business as usual for the planet, but most definitely not for us.
