Using years of experience in attribution science, a comprehensive study that links heat waves to individual emitters (ie fossil fuel producers) has just been published by @yannquilcaille.bsky.social et al. A systematic step forward as highlighted in my @nature.com News&Views article:

rdcu.be/eFpWu

Heatwaves linked to emissions of individual fossil-fuel and cement producers | Nature

The emissions of leading fossil-fuel and cement producers have been systematically linked to particular heatwaves. Three scientists discuss the methodology behind the result and its potential impact on climate-liability court cases.

The Earth has reached its first planetary climate tipping point - a global coral die-off due to rising ocean temperatures. Much marine life depends on functioning coral reefs, so this is scary news for global marine ecosystems and all who depend on them. grist.org/oceans/coral...

Corals are disappearing, pushing Earth to its first major ‘tipping point’

A new report says Earth has reached a dire milestone with the widespread death of warm-water coral reefs. It's not too late to save what remains.

Study suggests the Woodside’s Scarborough gas project off Western Australia could cause ⬆️ 484 heat-related deaths in Europe this century and destroy around ⬆️ 16 million corals on the Great Barrier Reef with each bleaching event.

Keep it in the ground!

theconversation.com/for-the-firs...

For the first time, we linked a new fossil fuel project to hundreds of deaths. Here’s the impact of Woodside’s Scarborough gas project

The results challenge claims that the climate risks posed by an individual fossil fuel project are negligible or cannot be quantified.

Why didn't Chinese fossil CO2 emissions peak in 2013?

It looked like Chinese emissions might peak in 2013, after declines in 2014 & 2015, but since then, improvements in the CO2 efficiency of the economy slowed significantly.

CO2 will peak if efficiency improvements return.

See ALT text.

The figure is a simplified Kaya Identity. The bars are the contributions to growth from GDP, Energy/GDP, CO2/Energy, and when you add the bars together you get the black dot, CO2 growth. For a given GDP, if the improvements in Energy/GDP and CO2/Energy are greater than the GDP growth, then emissions go down.

🌊 Marine heatwaves and the carbon cycle

A new study shows that marine heatwaves can disrupt food webs and carbon transport in the NE Pacific.

🔗 www.nature.com/articles/s41...

#SciComm #ClimateCrisis 🧪

Marine heatwaves modulate food webs and carbon transport processes - Nature Communications

A decade of BGC-Argo and plankton records shows North Pacific heatwaves reshape food webs and trap small particles in midwater, slowing deep-ocean carbon export. Impacts vary by event, underscoring the need for sustained ocean monitoring.

Exciting detective work 🤩

Ruth Mottram @ruthmottram.bsky.social · 7d

🚨 New @oceaniceeu.bsky.social preprint🚨 why has Antarctica stopped (net) losing mass, in spite of increased discharge?
Declining sea ice is part of the answer but increasingly heavy and frequent atmospheric rivers are most important factor.

Lots of important subtleties:
arxiv.org/abs/2510.03590

Screenshot of figures from the paper: Above a graph showing wiggly lines depicting the cumulative mass budget of Antarctica: a dark line swoops and wiggles downwards before stabilising at the end, colourful dashed lines (depicting snow fall) wiggle along constantly before sloping upwards at the same tme stabilisation occurs.
Below 6 maps of Antarctica in blues and red depicting the mass change in different basins.

Lokal ist das absolut korrekt. Die Gesamtbelastung mit Schadstoffen vmtl um einen Faktor 1-2 höher im Ruhrgebiet. In Leipzig soll das bis tief in die 1980er Jahre ebenfalls noch richtig krass gewesen sein. Dennoch ist der zeitliche Höhepunkt der Schadstoffbelastung ähnlich dem in Brüssel.

High profile statistics are often more representative of the model fingerprint, not the physics.
