Published today in Earth System Science Data: The Global Carbon Budget 2025 essd.copernicus.org/preprints/es...

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. Net is still a source...

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

New study led by Louise Busschaert @kuleuvenuniversity.bsky.social showing that the area of profitable rainfed maize production in Europe may shift north and expand with global warming. www.sciencedirect.com/science/arti...

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.

10 jaar na de klimaatconferentie van Parijs gaat het deze week in Belém over hoe we dat klimaatakkoord van Parijs in stand kunnen houden: "We moeten daarvoor zes keer meer doen dan wat nu op tafel ligt." www.vrt.be/vrtmax/luist...

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. Fossil fuel companies are deceiving the public and obstructing progress. www.theguardian.com/environment/...

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...

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.

"Parijs was speciaal omdat het de eerste keer was dat er een exact temperatuurdoel werd ingesteld. Het stellen van een doel was enorm belangrijk voor landen, ngo's, bedrijven enzovoort. Het geeft een richting aan." vrtnws.be/p.xZpjAKbyl

Extended hurricane category scale, following Wehner&Kossin, Proceedings of the National Academy 2024: www.pnas.org/doi/abs/10.1... If that scale didn't stop at Category 5 for historic reasons, we would have had several Category 6 tropical cyclones since year 2000.

I wanted to offer some thoughts on the Gates climate memo that has been circulating this week. While I can't directly speak for others, I can say that my own response is one of dismay & deep frustration (and that this view is shared by many climate/Earth scientists). [1/n]

Future changes in irrigation will reduce dry-heat stress (without reversing GHG trend) and will substantially amplify moist-heat stress (strengthening GHG trend). New study @natcomms.nature.com led by Yi Yao @hydr-vub.bsky.social and @usyseth.bsky.social www.nature.com/articles/s41...

#HurricaneMelissa was made about four times more likely by the #climatecrisis It's real, it's us, and it's here www.imperial.ac.uk/grantham/res...

A display of pure power from Hurricane Melissa today. Remarkable satellite imagery.

6 AM Tuesday morning #HurricaneMelissa approaches Jamaica. Horrifying next 24 hours says Dr. Shepherd. Pray. Been at this a long-time one of the most horrific, well-formed hurricanes I have ever seen. 175 mph winds and a direct landfall looming

World’s climate plans fall drastically short of action needed, analysis shows - Recent plans submitted to UN by more than 60 countries would cut carbon by only 10%, a sixth of what is needed #climatecrisis Story by @fionaharvey.bsky.social www.theguardian.com/environment/...

Op deze dag waarop belgische universiteiten protesteren tegen de kille besparingen op hoger onderwijs en wetenschappelijk onderzoek, komt deze boodschap van het Nobelprijscommité duidelijk binnen.

MILESTONE | Wind and solar generated OVER HALF of the UK’s electricity for the first time ⚡🇬🇧 Wind produced 7.7 TWh, while solar reached 1.7 TWh, driven by strong capacity growth and favourable weather conditions. From our Electricity Data Explorer 🔗 loom.ly/TwPNYos

MILESTONE | This September, EU solar generation already surpassed 2024's total. In the whole of 2024, solar generated 301 TWh of EU power. By September 2025, it reached 312 TWh. Get the latest data updates via Ember’s data explorer 🔍 https://ember-energy.org/data/electricity-data-explorer/

In our new study led by Delphine Ramon in @ioppublishing.bsky.social, we project exposure to dangerous heat stress around Lake Victoria under a high-end scenario. By end of century, up to 122 million people may experience dangerous heat stress for more than 5% of the year doi.org/10.1088/1748...

🏭 A VUB report shows Belgian industry can cut emissions by 90% by 2040. Key steps are electrifying heat and using carbon capture. But the next 5 years are crucial for building CO₂ and power grid infrastructure. Action is needed now. #ClimateAction #Belgium 🔗 www.brussels-school.be/research/pub...

Don't sleep on the good news, folks. It's rare these days. www.carbonbrief.org/analysis-ind...

"ja, ons land kan zijn industrie behouden én de uitstoot tegelijk sterk terugdringen. Het is [...] mogelijk om de CO2-uitstoot tegen 2050 met minstens 90 % af te bouwen. Bovendien kan dat met technologieën die vandaag al bestaan, of ten laatste tegen 2040 beschikbaar [..] zijn" vrtnws.be/p.8e0Eb9WJM

The summer is over - and for about 16,600 people across 854 European cities that doesn't mean autumn comes, but death. People who would still be alive if it wasn't for our burning of fossil fuels. - New study with @lshtm.bsky.social www.imperial.ac.uk/grantham/pub...

🏭 A new Nature study (incl. VUB) links heatwaves to carbon majors. For 🇧🇪 Belgium’s 2003 & 2022 heatwaves, China Coal was the top corporate contributor. 25% of all studied heatwaves were ‘virtually impossible’ without climate change. 🔗 doi.org/10.1038/s415...

A paper in Nature suggests a quarter of heatwave events from 2000-23 would have been near impossible without anthropogenic climate change. The paper also indicates that major carbon emitters are responsible for around 50% of the increase in intensity of these events. ⚒️ 🧪

New Study: All recent global heatwaves have been amplified by man-made climate change, with one-quarter of these events being virtually impossible without climate change. Paper in thread… 1/

🚨📈 Over the last 6 months a series of papers has advanced our understanding of the culpability of fossil fuel firms for climate change impacts. In April, @jsmankin.bsky.social and I showed that economic damages from rising extreme heat can be linked to companies like Exxon and Chevron. rdcu.be/ei0T5

In our new paper @nature.com led by @yannquilcaille.bsky.social, we systematically quantify how each of the 180 carbon majors contributed to the increased probability and intensity of 213 individual heatwaves 🧵 www.nature.com/articles/s41...

"Het risico dat we kritieke drempels overschrijden neemt met elke 0,1 graad verdere opwarming toe. We spelen nu poker met de planeet. Als je ziet wat er op het spel staat als we verliezen, doen we dat beter niet." @wimthiery.bsky.social www.demorgen.be/nieuws/wanne...

Everything we've made will break, buildings and streets will crumble, and cities will be abandoned. But the CO₂ we emit into the atmosphere will persist for centuries, and the climatic impacts will last longer than human civilization has existed. This is our legacy for the future.

Melting over 80.6% of the area of the Greenland Ice Sheet. This is the highest value in our data set, which starts in 1981. @polarportal.bsky.social
