With its low computational cost and calibration accuracy, our emulator offers an efficient tool for exploring AMOC dynamics in future climatic scenarios. Finally, the methods used to develop this emulator are generalizable, providing a framework for studying other tipping elements in research

In our new study led by @amaurylaridon.bsky.social in #ORE, we present a nonlinear two-forcing emulator for the #AMOC. By accounting for Greenland Ice Sheet melt, it captures 3 additional collapse trajectories for scenarios SSP3-7.0 to SSP5-8.5. open-research-europe.ec.europa.eu/articles/5-87

Today, DOE renamed the National Renewable Energy Laboratory (NREL), one of the crown jewels of U.S. science and engineering for renewable energy, the National Laboratory of the Rockies (NLR). We should be reinvesting in our world-leading national labs not renaming them. www.nrel.gov/news/detail/...

📅 Official abstract submission deadline is 15 January 2026, 13:00 CET

Convened by Ryan Teuling, @innevanderkelen.bsky.social, Diego Miralles, and @soniaseneviratne.bsky.social and myself

📢 Working on land atmosphere-interactions and their role in shaping climate extremes?

🌍 Consider submitting an abstract to our European Geosciences Union (@egu.eu) 2026 session:

Land-atmosphere interactions and climate extremes (CL4.4): meetingorganizer.copernicus.org/EGU26/sessio...

I really wish we'd stop calling them climate "skeptics" or "vaccine skeptics", if you jump off a cliff we don't call you a "gravity skeptic"

⚖️ Are you working on topics that could be relevant for climate litigation?

➡️ Submit an abstract to our outreach session (which allows you to submit a second abstract)

Changing European hydroclimate under a collapsed AMOC in the Community Earth System Model Abstract. The Atlantic Meridional Overturning Circulation (AMOC) is expected to weaken or even collapse under anthropogenic climate change. Given the importance of the AMOC in the present-day climate,...

📢 New paper on the impacts of AMOC collapse on European hydroclimate. 🌊

We find an AMOC collapse would exacerbate drought conditions across Europe, linked to reduced precipitation. In combination with climate change droughts are expected to become more frequent and severe.

First electric cars and buses, now trucks: in the past we were often told that electric trucks would not be feasible.

But the market is picking up speed and electric trucks have become a reality. Expectations are for significant market expansion in the coming years.

Time is up for 1.5°C. The remaining carbon budget for 1.5°C is virtually exhausted: 170 GtCO2, equivalent to 4 years at the 2025 emissions levels.

Annual emissions from permanent deforestation declined over 2015–2024 but remain high at around 3.9 GtCO2. Removals through permanent af/reforestation are 2.2 GtCO2 per year over the same period.

Still no peak. Emissions are projected to increase by 1.1% in 2025, reaching 38.1 GtCO2. An all time high.

Many congratulations to the amazing @frediotto.bsky.social for receiving the Hans Oeschger Medal! This career award from the @egu.eu Climate Division underlines the ground-breaking research Fredi did on many fronts, most notably on near-realtime extreme event attribution @wwattribution.bsky.social

Solar’s price drop is astonishing: panels are now 98% cheaper than when I first analyzed them in 2004.

Today, building a fence with solar can be cheaper than using wood.

Missing 1.5C climate target is a moral failure, Guterres tells Cop30 summit UN secretary general urges opening session in Brazil to bring about a ‘fundamental paradigm shift’

Guterres is right.
Even a temporary overshoot could unleash far greater destruction and costs for every nation. It could push ecosystems past catastrophic and irreversible tipping points.

If we do not seriously move away from burning fossil fuels, hurricanes like Melissa will only become worse. Already today Melissa tested the limits of what preparedness and adaptation can do. These limits are very real for everyone in the Caribbean. www.worldweatherattribution.org/climate-chan...

When Irrigation Backfires Global farming practices are driving heat stress and water strain, VUB researchers warn

VUB press release about Yi Yao's three publications on irrigation-climate interactions: www.vub.be/en/news/when...

This is the second study analyzing the outputs of the @wcrp-cmip.org endorsed #IRRMIP project. It's also the third paper led by the amazing Yi Yao (VUB PhD graduate), coming out this year. bsky.app/profile/wimt...

For example, irrigation expansion more then doubled the trend in water loss to the atmosphere (P-E) in South Asia after 1960. As a consequence, the local terrestrial water storage (TWS) depletes over time following irrigation expansion.

Irrigation-induced land water depletion aggravated by climate change - Nature Water The rapid expansion of agricultural irrigation raises concerns about exacerbating water scarcity, but land–atmosphere interactions are often overlooked. This study isolates irrigation impacts from oth...

In our new study @natwater.nature.com led by Yi Yao @ethz.ch, we show that irrigation expansion in many regions substantially decreases the net water influx from the atmosphere to land, further aggravating the existing drying trends caused by climate change www.nature.com/articles/s44...

Two years ago, the @esabcc.bsky.social published its advice on the EU's 2040 emissions reduction target. We indicated a 90-95% reduction relative 1990 levels.

Today, EU climate ministers agreed on a 90% target, with an 66.25-72.5% reduction as part for its new NDC for 2035.

Today is the official launch of this year's @unep.org #EmissionsGap report.

It's title says it all

OFF TARGET

that's true for progress, NDCs and implementation

What is the current state of climate action? What do latest country pledges add up to?
And how much global warming are we in for? 🌍🌡️ 🔥
For the 16th year in a row, we publish the @unep.org #emissionsgap report.
As usual, I looked the assessment of the global gap and its global warming implications.
