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.

Carbon offsets fail to cut global heating due to ‘intractable’ systemic problems, study says
Analysis of 25 years of evidence shows most schemes are poor quality and fail to lower emissions

Geoengineer polar glaciers to slow sea-level rise
Stalling the fastest flows of ice into the oceans would buy us a few centuries to deal with climate change and protect coasts, argue John C. Moore and colleagues.

🌊 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.

Carbon offsetting suffers from deep-seated systemic problems that incremental change will not solve says review paper from Oxford Uni

“We have assessed 25 years of evidence and almost everything up until this point has failed”

🚨 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:

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.

🚨🌊 New highlight paper out today in Earth System Dynamics!

We find an observational constraint implying more future global ocean heat uptake, cloud feedback, and warming than the CMIP6 mean.

This contrasts with previous estimates based on past warming trends.

Abstract. The ocean takes up over 90 % of the excess heat stored in the Earth system as a result of anthropogenic climate change, which has led to sea level rise and an intensification of marine extre...

We finally have a new paper out looking at how summary statistics from the AR6 scenario database are highly dependent on the sampling of the database.

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

Two curves show how the median is different depending on the scenario.

Nicht sicher, wie die Ortsauswahl genau zustande gekommen ist, aber man kann bspw auf Brüssel in Belgien gehen, das ist relativ nah dran. Klar ist lokal immer nochmal mehr Pollution, aber der grobe zeitliche Verlauf ist derselbe (und generell in Westeuropa überall recht ähnlich).

Yellow and red stripes with white vertical line to demonstrate the temporal evolution of aerosol pollution in Germany. Blueish stripes since 2019 on the very right side of the plot. Yellow and red bars with two dashed grey vertical lines to show where very poor air quality begins (upper) and what the actual WHO guideline is (lower). Blueish bars since 2019 on the very right side of the plot.

#StormAmy probably being named very soon as models are in better agreement this morning. It could be a record-breaker in terms of low pressure for the time of year as well.
W + N Scotland in particular is likely to see some intense winds with this one.
