How much carbon budget do we have left if we want to stay below 1.5˚C? Just 2 more years at current rates. It is essentially impossible to avoid global temperature rise exceeding 1.5˚C. climatelabbook.substack.com/p/the-shrink...

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

China’s CO2 emissions have now been flat or falling for 18 months, starting in March 2024. This trend continued in the third quarter of 2025, when emissions were unchanged year-on-year. If this trend starts to move into sustained carbon emissions reduction it would be hugely significant.

"As a scientist, I've never had reason to be so concerned as I am today for the future we are facing," states PIK Director Johan Rockström as #COP30 kicks off in Belém, Brazil. The first ever Planetary Science Pavilion, under the mandate from COP30 Brazil, and together with Carlos A. Nobre,... 1/2

Enhanced Rock Weathering Promotes Soil Organic Carbon Accumulation: A Global Meta‐Analysis Based on Experimental Evidence 📄

Good news: carbon intensity has declined Bad news: carbon emissions increased, due to the rapid rise in world GDP Also bad news: the chance of staying below 2°C remained low, at 17% Better news: chance of going above 3°C has gone down substantially, from 26% to 9%

🧵 As the #OvershootConference drew to a close today, the final plenary offered a space to step back and reflect across themes. What stood out was both the urgency and interconnectedness of the challenges we face when confronting climate overshoot:

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. ⚒️ 🧪

We are organizing a session on The biogeochemistry of Enhanced Mineral Weathering at BIOGEOMON 2026! 📍 Umeå, Sweden | 📅 June 8–11, 2026 Conference theme: “Ecosystems in Transition” — exploring the dynamic changes shaping our natural world. www.slu.se/biogeomon2026 #EnhancedWeathering #ERW

NEW STUDY: How much CO2 can we safely store in geological formations? In a new @nature.com study, we cross-check established academic and industry estimates with various risk factors. We find a prudent geological CO2 storage limit that is about 10x smaller. /1

Bomen planten is geen magische klimaatoplossing. De impact is veel beperkter dan vaak wordt aangenomen. - Minder land beschikbaar dan gedacht. - CO₂ opslag veel kleiner dan uitstoot. - Ontbossing stoppen = meer klimaatwinst dan nieuwe bossen aanleggen. globalchangeecology.blog/2025/08/29/b...

New assessment on the biophysical potential of forestation to sequester carbon. As expected, we found just a fraction of what other assessments found, because we considered the obvious no-nos, such as risk to biodiversity, excess water use, and regional warming. theconversation.com/the-climate-...

We see here a self-styled "honest broker" with decades of experience in downplaying climate change presenting an age-old climate denial trope: using *annual* rainfall data as argument against an increase in *extreme* rainfall. Does he *really* not know better? Or assume his readers won't? 🧵1/5

Ours is the first study to demonstrate an historical increase (by a factor of three!) in the occurrence of atmospheric resonance, which is associated with many of the most devastating and deadly persistent summer weather extremes in recent years (e.g. Pacific Northwest Heat Dome of summer '21) 🧵

Is global warming accelerating? Over at The Climate Brink I argue that the consilience of evidence from surface temperatures, climate models, forcing changes, ocean heat content, and earth energy imbalance all point toward yes: www.theclimatebrink....

Current #MRV for #EnhancedWeathering focuses on bicarbonate export, but this may not capture total #CarbonRemoval, especially when soil retention is high. We propose a cation-based MRV using solid soil samples as a more practical & reliable alternative. egusphere.copernicus.org/preprints/20...
