🔎Recent research highlights the complexity of newly assimilated C partitioning in moso bamboo forests and suggest that clonal integration may mitigate drought-induced dieback.🎍

Important.
National GHG inventories call most lands “managed” and thus include huge amounts of CO2 removals from tree growth, resulting in net-negative emissions.
Bookkeeping approach quantifies emissions and removals only directly linked to human activities, resulting in net-positive emissions.
Behold, the biggest point source of CO2 outside humanity, the volcanic system of Nyiragongo and Nyamuragira in the DRC, which emits an astonishing 16 thousand tons of CO2 a day (we emit over 100 million tons a day)

A few years ago, @shannonosaka.bsky.social and I wrote about a fire that burned the largest forest carbon offset project in California. grist.org/climate/this...
Now the project is officially dead. 🧵 1/3

EU adopts -90% emission reduction target for 2040, and max 5% of that by 'high-quality international targets', i.e. reductions elsewhere. 14 years to go and a *lot* of work to be done!
🔥HOT OFF THE PRESS: Why the energy transition is disruptive, non-linear, hard to predict and often faster than expected.
Our paper in Nature Reviews Clean Technology shows how feedback loops create virtuous and vicious cycles that can accelerate or block change. 🧵

For a decade, the Shared Socioeconomics Pathways #SSP are used for scenario research related to climate change mitigation.
Now, GDP & population projections were updated by @iiasa.ac.at & the team at the #OECD, and the #ScenarioServices team set up a new interactive app to explore the scenarios!
One of most mind-boggling things about climate change is how much faster it is than planet can accommodate. It takes ~1,000 years for deep water to mix with surface (as Scott Denning puts it "The deep water does not know we are here yet!"), and some Earth processes that remove CO2 take 100,000 years
New discussion paper just dropped that’s taken shall we say a little work to get this far … essd.copernicus.org/preprints/es... please be kind. Not on an at all sensitive topic in the slightest.

Ancient pine trees growing in eastern Spain have quietly recorded more than five centuries of Mediterranean weather. Analysis of tree rings clearly shows that todays storms and droughts are becoming more intense and more frequent than almost anything the region has experienced since the early 1500s.
If you think gas power is cheap, meet Keadby 2, the last CCGT gas plant built in Great Britain
It opened in 2023, after 5yrs of development, at a cost of £350m
Owner SSE says it would now cost 3.5x to build the same plant (~£1.2bn)

Considering the significant tone shift of Renew, the socialists, and the EPP, it seems that Europe has entered a new political equilibrium that will lead to a more forceful response against the United States
Atmospheric CO2 concentration increased by a record-high 3.7 ppm in 2024, mainly due to the 2023/2024 El Nino conditions weakening the land sink.
The 2025 projection is for a rise of 2.3 ppm, close to the decadal mean of 2.6 ppm, suggesting the land sink has returned to its pre-El Nino level.

📢Global Carbon Budget 2025📢
Fossil CO2 emissions continue to rise in 2025 while the terrestrial carbon sink recovers to pre-El Niño strength.
The key findings are covered in two reports this year:

Controversial! I've always argued that 5-story wooden buildings weren't anything special 100 yrs ago. In Germany, we've had to fight to make it happen again, so it leads to dispute.
...A few examples. Starting with 'Alter Bau'. Yes, it's just called 'Old Building'.

Bar graph showing global ocean heat content change in the upper 2000 m from the late 1950s through 2025. There is a long-term warming in the time series, which is using IAP/CAS data.
2025 was the hottest year on record for ocean heat content. Unfortunately, we now say this every year. 🥹
"In addition to setting a new record in 2025, the global
ocean continues to show sustained and intensified warming."

Having majored in IR, it’s fascinating to watch, to put it positively 😬
The effect isn’t obvious to me. It could be beneficial for negotiations if detractors are not part of the process
5/This is part of what @segoddard.bsky.social and I have called a neo-royalist order. Elite cliques use economic and material interdependencies to bolster their power. Think elite interests (Trump and his inner circle) not national interests.

The Windley Key Fossil Reef, an old limestone quarry that provides a cross-section of a coral reef from 120,000 years ago
Made a pilgrimage to 2 ghosts of sea level past & future in Florida, from last time global temp was similar to today 120,000 years ago: an outcrop of oolite in Miami from when it was a sandy shoal under the waves, and in Windley Key a fossil coral reef that now ominously sits 20 feet above sea level
For nonlawyers, it’s worth noting that statements like this have—as a formal matter—important legal effects as a matter of international law. If such statements are *not* made, and in volume, future arguments that Trump’s invasion sets a legal precedent will stand on much firmer legal ground.
"If we are going to go all in on a fossil fuel future in the U.S., it probably would be good to check if we have the fossil fuels to do that." Geology strikes back
Hydrogen does not directly warm the climate, but interacts with OH to extend the life of CH4.
"More hydrogen means fewer detergents [OH] in the atmosphere, causing methane to persist longer &, therefore, warm the climate longer"
