Sind alle anderen dumm?
Oder womöglich doch wir?

Germany's ambassador to the U.K. Susanne Baumann presents Professor Friederike Otto with The Cross of the Order of Merit of the Federal Republic of Germany

We’re excited to announce that @frediotto.bsky.social has been awarded Germany’s highest honour for her groundbreaking work on climate science and extreme weather.

The award recognises her pivotal role in revolutionising attribution science: connecting extreme weather events to climate change.

If we made the green energy transition this war would be unthinkable and these authoritarians wouldn’t be in power — not in the US, not in Iran, not in Saudi Arabia, not in Russia. Hydrocarbons are killing our freedom and just plain killing us.

CMIP6 trends over the last 13 years (red) and the 13 years before (black) (using the screened simulations), along with the estimate trends from FR26 over (roughly) the same periods.

Is there an acceleration in global warming expected in the CMIP6 climate models? yes! But not as easy to detect in the real world.

"Zwischen der Erde und der Sonne ist die Atmosphäre.

Und wenn die immer dünner wird, dann wird die Sonne immer heißer.

Und der Grund dafür sind Abgase, CO₂ und und und"

I don't want self-driving cars. I want cars with speed governors and doors that won't open when cyclists are approaching.

Very on the nose that in the US, a rodent has replaced scientists. It currently feels like 6 more years of winter.

Let’s save the National Center for Atmospheric Research, the prime climate research lab in the US. ✊

Yet more evidence that the crucial Atlantic overturning circulation #AMOC is weakening.
Bad news for our climate future.
More reason to finally get serious about ending fossil fuel use.
As fast as we can.

Three Years of Field Trials Indicate a Sustained Enhanced Rock Weathering Signal with Limited CO2 Removal Enhanced rock weathering (ERW) is a CO2 removal technology that involves spreading finely ground silicate rock on fields. The chemical weathering of this rock powder removes atmospheric CO2 in the form of bicarbonate ions and secondary carbonates. Despite some promising theoretical simulations and laboratory findings, results from field trials that evaluate the ERW’s impact on soil biogeochemistry and CO2 removal are still scarce. This study investigated the impact of basaltic rock powder applied at the equivalent rate of 20 t per hectare (2 kg m–2) in three temperate vineyard fields in Switzerland over 1000 days. Analyses of soil pore water revealed that most standard ERW monitoring proxies (pH, electrical conductivity, total dissolved inorganic carbon, calcium, and magnesium concentrations) did not increase significantly. By contrast, sodium concentration in soil pore water was on average 3-fold higher in the rock powder-treated plots, indicating active mineral dissolution. Integrating the pore water results with model analyses, we estimated that the average CO2 removal rate was 100 ± 30 kg CO2 ha–1 yr–1, which is 10 to 30 times lower than the upper rates reported in some previous modeling and experimental studies. Future work is now needed to improve our understanding of ERW’s CO2 removal potential and soil contamination under a variety of soils, rock feedstocks, and climate conditions.

A three-year Swiss study found that enhanced rock weathering (ERW) removed 10 to 30 times less CO₂ than expected due to soil chemistry and local climate.

Don’t panic, we’ve got the Hitchhiker's Guide to Antarctica . . . for scientific instruments that is! Our SCARGO instrument is hitching a ride on planes flying to and from Antarctica's McMurdo Station to gather vital data on the carbon cycle in the Southern Ocean. Learn more: https://bit.ly/4auVMLB

Many people think about cold in Northern Europe if the Atlantic Ocean current system #AMOC fails. But that wouldn’t be the only problem for Europe by far.
This new study shows that severe drought is another one. 🌊

Réchauffement : peut-on réduire le CO2 océanique ?

Face à l’urgence climatique, les techniques d’élimination du CO₂ dissous dans l’océan suscitent espoirs autant qu’inquiétudes. Comment procéder ? Quelles règles se donner ? Qui doit décider ? Les éclairages du biogéochimiste Olivier Sulpis, chargé d’évaluer ces méthodes.

This study by my colleagues at University of Hawaiʻi at Mānoa shows that deep sea mining waste to be released near the ocean surface would disrupt marine food webs.

The same would be true of grinding and spreading rocks in the ocean for CO₂ removal. 🌊

A new paper, led by GO-BGC researcher @koelling.bsky.social, using @bgc-argo.bsky.social data, examines ocean ventilation in the subpolar North Atlantic. These insights enhance our understanding of how oxygen enters the deep ocean and may aid in predicting future oxygen loss due to climate change.
