* CO2 record high, but growth nearly ground to halt
* Clean energy shaved 3bn tonnes off CO2
* Fossil-fuel power pushed into reverse
* Age of Electricity "confirmed"

In @theconversation.com @rubenpruetz.bsky.social, @joerirogelj.bsky.social, Sabine Fuss and Gaurav Ganti write that carbon removal strategies may conflict with biodiversity conservation in many instances: for example, planting trees and energy crops in pristine ecosystems such as savannas.
So... now we can breathe again. Let's talk about ScenarioMIP.
The final version is now up on GMD - and there's some changes since the first draft. /THREAD/

Planting trees or growing crops to remove carbon can help us fight climate change. But done in the wrong places or ways, it can also harm ecosystems. 👇
Not all tree planting is equally beneficial for the climate. Careful planning and site selection are key for effective carbon removal, write PIK’s Ruben Prütz and co-authors. They summarize their findings in an article for The Conversation:: theconversation.com/planting-tre...

two images describing the March heat wave, left a map showing temperature anomalies, right, the seasonal cycle and the anomalies this year
March in Western North America is deadly hot, completely above temperatures that would have been possible without climate change from burning oil, coal and gas. New record shatteringly rapid @wwattribution.bsky.social study www.worldweatherattribution.org/record-shatt...
Sunset over LA - one of the areas currently experiencing extreme early season heat.
RAPID ANALYSIS: It would be ‘virtually impossible’ for the record-breaking March heat currently scorching the U.S. West to occur without climate change.
We are seeing summer-like temperatures arrive exceptionally early from the Pacific to the Rockies this week. 🧵1/4
My latest for @mongabay.com: Planting trees helps fight climate change & restore biodiversity. But a new study finds that land-intensive carbon removal projects like reforestation or bioenergy crops often overlap with global biodiversity hotspots.
A two-column status table titled "Stage" and "Start Date" tracks the timeline of a manuscript submission from its preliminary data submission on October 8, 2025, to its eventual withdrawal on March 2, 2026. The log reveals a lengthy and repetitive administrative process, particularly between October 26, 2025, and February 19, 2026, where the status cycled more than ten times between "Contacting Potential Reviewers" and "Waiting for Reviewer Assignment," suggesting significant difficulty in securing peer reviewers. Following these numerous failed attempts to move into the active review phase, the final entry shows the manuscript was officially withdrawn on March 2, 2026, at 09:08:18.
My first paper had to be mailed to Stockholm, Sweden, and then mailed to reviewers around the world. Everything by mail! It was submitted, reviewed, revised, typeset, and published in 3 months. I feel bad for early-career scientists who can't find a single reviewer after 5 months. It's gotta change.
Essential reporting by @readfearn.bsky.social for @theguardian.com
As humid heat intensifies, millions worldwide face serious health risks
Outdoor workers, especially builders & farm labourers, are on the frontline
Such extremes are deadly not only for people, but other mammals too #ClimateCrisis
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!
👇 Last week, we published a study in Nature Climate Change on the implications that #CDR may have on biodiversity (see detailed post below).
⏳ In case you are interested but don’t have time to read it, here is a two-page research briefing: rdcu.be/e2vSY
📑 Underlying study: doi.org/10.1038/s415...
After four months, the journal has not found a single reviewer for my PhD student's manuscript. The academic peer review system is broken.
I think we all should:
1. Review three papers for every one that we submit.
2. Promptly declined to review a paper when the request arrives.

Climate solutions can clash with nature: 1.5°C pathways may place land-intensive CDR on up to 13% of high-biodiversity areas.
Protecting hotspots could remove over half of planned CDR land, unless we design climate action for nature too.

CO₂ removal requires careful site selection to avoid harm to #biodiversity, a new study shows. At the same time, researchers find that the cooling effects of #CDR can benefit biodiversity: www.pik-potsdam.de/en/news/late...

The study also reveals a similar tension in the opposite direction: under strict enforcement of the internationally agreed Kunming-Montreal Global Biodiversity Framework, more than 50% of land allocated for CDR deployment could become unavailable.
The authors argue that climate refugia, areas relatively unaffected by climate change, and biodiversity hotspots are both at risk.
The study also found that non-high income countries have a disproportionately high land allocation for forestation in climate refugia areas.
The paper concludes that limited use and careful siting of CDR can limit its negative biodiversity consequences and may even bring direct benefits to biodiversity – either through avoided warming or direct co-benefits.

Countries' carbon dioxide removal plans pose substantial threats to biodiversity, new research reveals.
Analysis by the scientists shows that up to 13% of global areas of high biodiversity importance are allocated for land-intensive CDR deployment. 🧵

Interesting for scientists working with scenarios: As part of our study, we made the gridded land allocation data for the original SSP-RCP scenarios from the participating model frameworks publicly available. 🔓👍
This project, which began more than three years ago, was made possible by a large, cross-institutional, multidisciplinary team of scientists who brought together diverse expertise and rich datasets. 👩🔬👨🔬
With our study, we provide entry points for more biodiversity-sensitive and equitable siting of CDR in climate action planning and scenario development. 🎯🤝
Thus, we need to:
- cut emissions deeply to limit CDR dependence. This can give us wiggle room to minimize risks. 🏛️🇺🇳
- refine model-based land allocation patterns to take biodiversity better into account. 📍🧩
- further study positive and negative implications of CDR and how they are distributed. 🔦🗺️
Nonetheless, we also show how, if implemented carefully, CDR may substantially benefit biodiversity by reducing warming-related habitat loss. ✅🛡️
Strikingly, biodiversity areas are disproportionately allocated in non-high income countries – countries that have contributed little to causing climate change. ⚖️🌡️
We find that scenarios allocate substantial parts of critical biodiversity areas for CDR. Many of these overlaps fall in places where CDR is considered unsuitable from an #ecosystem perspective. ❌❌
