The ensemble mean of today's IFS subseasonal forecast now predicts the earliest major sudden stratospheric warming in reliable records, beating 28 November 1968.

Will this verify? 👀

New national climate plans have barely moved the needle on limiting global warming. Yet there is hope.

According to UNEP's latest #EmissionsGap Report, accelerated adoption of renewable energy and falling costs mean we have the tools to cut emissions now: www.unep.org/news-and-sto...

📢 New paper out!

🌊 We discuss how well mechanisms of variability in the subpolar gyre are represented in climate models, finding that models that do this best are also the models in which abrupt shifts are found 😬.

It's a technical story, so here's a simple overview 🧵

Causal mechanisms of subpolar gyre variability in CMIP6 models
Abstract. The subpolar gyre is at risk of crossing a tipping point under future climate change associated with the collapse of deep convection. As such, tipping can have significant climate impacts; i...

🪸 Coral reefs are already reaching breaking point - and we're rapidly approaching other critical climate red lines.

That's according to the latest tipping points report that came out last week.

Cartoon waarop een dorpje achter de dijk te zien is. Op zee staat een rij gigantische dominostenen die zich uitstrekt tot de horizon. In de verte zien we vallende stenen die snel dichterbij komen. Op de voorste steen, het dichtste bij de dijk, staat 'klimaatcrisis'. In de straat in het dorp protesteert een groep exteemrechtse demonstranten tegen immigranten. Slechts twee schapen en een jongetje op de dijk kijken naar de vallende dominostenen.

🔥✊Urgent en ingrijpend, maar noem het liever niet radicaal. Met huidige klimaatbeleid stevenen we af op 2,7C opwarming in 2100, want een ongekende ontwrichting van de samenleving zou betekenen. Dat niet serieus nemen, dát is radicaal!

“If we continue, however, with the policies that we have out there, we are clearly on a pathway now of 2.7 degrees or 3 degrees where adaptation is simply not doable anymore. This is just what it is. We cannot protect Amsterdam from sea level rise of 3m. This is just not doable,” Thallinger said.

🚨 NEW: Climate change is already causing 30,000 deaths per year - a global annual economic loss of $100-350B USD - but the true damage is probably 10x higher. Out TODAY in Nature Climate Change: the first systematic look at the science of "health impact attribution" 🔓 www.nature.com/articles/s41...
"Health losses attributed to anthropogenic climate change," a brief communication in the journal Nature Climate Change. There's a map showing regions of the world, and pie charts of relevant studies as they apply to different health impacts like "heat-related deaths" and "maternal and child health"

This is a nice illustration of how waste powers production.

The idea of single-use, discardable plastic 'filling up landfills' was magic for producers.

This is the same principle behind fossil fuel companies producing energy, and the tech companies that waste it

Interesting new study! They attributed heatwaves🔥 to emissions of individual companies. Companies that emit a lot of CO2 contribute to climate change, making heatwaves more intense. Can this help in pushing them to reduce emissions and hold them accountable for the damage?

Systematic attribution of heatwaves to the emissions of carbon majors - Nature
Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.

Wow. The US Energy Department has withdrawn its scam climate report and disbanded its „Climate Working Group“ in order to dodge a law suit against the scam.
They must have realized that this scam report by a few „climate skeptics“ is indefensible nonsense.
