New study: most climate models underestimate the decline of the Atlantic overturning circulation #AMOC. The AMOC is on course to slow by more than 50% by the end of the century. 🌊
Very likely the AMOC will then be past the tipping point for full shutdown. 😨
us.cnn.com/2026/04/16/c...
The #AMOC by 2100 will thus be so weak (~8 Sv) that it is very likely on the way to full shutdown, as our study last year showed: iopscience.iop.org/article/10.1...
In my view, this now makes a full #AMOC shutdown more likely than not. Definitely not a low likelihood risk, as we used to think.
Breaking: New study using observational constraints projects that the Atlantic Ocean circulation #AMOC will weaken ~50% by 2100, even for medium emissions and without Greenland melting. 🌊
More realistic models means stronger weakening - not entirely unexpected.

Halfway down today’s Guardian front page. Is a catastrophic breakdown of the Atlantic is too big for some to comprehend? “I now am increasingly worried that we may well pass that #Amoc shutdown tipping point, where it becomes inevitable, in the middle of this century, which is quite close.” #r4today
Heat batteries delivering up to 1,200C using off peak electricity:
A Scottish whisky distillery just claimed a world first — producing high-temperature steam for distilling using stored green electricity instead of fossil fuels.

Heat batteries are a game changer for decarbonising heat.
Polar Night Energy and Lahti Energia Oy have partnered to construct what is expected to become the world’s largest sand-based thermal energy storage system, to be built in Vääksy, Finland.

Denmark didn’t “transition” its grid—it replaced it.
~15% → 92% renewable electricity in 25 years.
Wind did the heavy lifting. Solar is scaling. Interconnection balanced. Flexibility solved variability.
Wind built it. Solar is scaling. Fossil lost it.
This IS system replacement. ⚡#Bettrification
In the special issue described in this editorial, working with several developing country teams, we articulated practical bottom-up guidance for reaching net-zero across the economy in key sectors: power, transport, industry and AFOLU, and in the context of countries' other goals @iddri.bsky.social

MMM ajaa metsäteollisuuden etuja ehdottamalla, että boreaalisten luonnonmetsien ikärajaa nostetaan ennallistamissuunnitelman valmistelemisen yhteydessä. Tämä tarkoittaisi sitä, että 100 000:ta jalkapallokentällistä vastaava määrä metsää jää yhä suojelun ulkopuolelle.

This is why it’s important to study what the planet might look like under RCP8.5, even if the model scenario that gets us to that forcing is outdated: because the most extreme climate impacts might emerge at a much lower level of warming than previously assumed.
NEW from us: India's CO2 emission growth slowed to less than 1% in 2025, the slowest rate in two decades, outside of the Covid drop. This was in part due to record clean energy growth which helped push down power sector emissions and is projected to accelerate this year.
Only half of the calories produced on croplands are available as food for human consumption - new research
The rest? Livestock and biofuels mostly

The global food system is systemically fragile in the same way that the global financial system was before the 2008 crash. If it goes it down, we’re looking, as complex societies, at a potential termination event.

The 'green' fuel market supplying Europe with used cooking oil, appears to be rife with fraud.
An investigation by SVT has uncovered that the world's largest producer of biofuel for aviation, Neste, is likely receiving virgin palm oil instead of recycled frying oil.
Seems like the Finnish state owned oil company #Neste has not been too accurate, when reporting about the origins of it's #aviation #biofuel...

The Central England temperature record represents the longest series of monthly temperature observations in existence.
Recent temperatures there are over 1.5 degrees Celsius above the 1961-1990 average, and over 2 degrees above preindustrial values.

We’re in danger.
Gas only sets Spain's electricity price 15% of the time. When gas costs spike it barely registers on the electricity bill. In countries like Italy and the UK gas sets the price 90% of the time. The difference is enormous.
I spoke to @politico.com about this.

The fast evolution of airborne drone & robotic ground combat in Ukraine & the Gulf, civilian EVs, roboticized factories, and AI are just different facets of the same technological & industrial digitized, electric transition, a bigger story than almost anything going on right now.
This is dire news (and you don't need to like Hansen in order to appreciate the science he is doing / has done).
If the equilibrium climate sensitivity for double CO2 is really 4-5C instead of 3C, that changes the whole future trajectory.

rightwing media narratives are fuelling a false backlash against climate action
An echo chamber of elite opinion, has led to MPs significantly underestimating public support for climate policies and overestimate public opposition to local clean energy projects

Swedish old-growth forests store 78-89% more carbon than managed forests do, a difference in carbon storage larger than Sweden’s cumulative emissions from the combustion of fossil fuels since 1834.
The same probably also applies to Finland.

Spain's renewables build-out has structurally decoupled its electricity prices from gas markets. Gas now sets the price in only 15% of hours, compared to 90% in Italy.
Countries that invested early in clean power are far less exposed to fossil fuel price shocks. Those that didn't now pay the price.
