There is No Scientific Justification to Revoke the Endangerment Finding The U.S. EPA's decision to repeal the Endangerment Finding will limit the government's ability to regulate emissions of carbon dioxide and other greenhouse gases under the Clean Air Act.

As I say here, there is no scientific justification to revoke the engagement finding. In fact, over the last 15+ yrs, the evidence of how climate change affects our health has only grown. Higher risk of allergies, dementia, fertility, heart disease, and death: that’s what’s on the line. @nature.org

In Kopenhagen gibt es die Vorschrift, dass alle wichtigen Radwege bei Schneefall bis spätestens 08:00 Uhr morgens geräumt sein müssen, damit die Menschen sicher mit dem Fahrrad zur Arbeit fahren können. So sieht dass dann aus❤️😀

Combined Effects of Air Humidity and Temperature on Biogenic Volatile Organic Compound Emissions and Photosynthesis Temperature is the primary driver of biogenic volatile organic compound emissions, but humidity also enhances emission rates Biogenic volatile organic compounds have different sensitivities to hu...

Really excited to share this paper from Mj Riches @chemj.bsky.social showing a humidity dependence on VOC emissions from ponderosa pines. At higher RH, emissions increase substantially - and we explore a few possible mechanisms in the paper.

Neue Schulaktion: anspruchsvoll und faszinierend!

After reviewing nearly 200 applications from prospective grad students and postdocs over the past few months for a couple different 🧪⚒️ postings, here are some tips, at least as they apply to North American positions. I hope they help future applicants. Share with your networks. 🧵

Einem Philosophie (!) Professor in Texas wurde verboten, bestimmte Werke von #Plato (!) im Unterricht zu nutzen, sie wurden zensiert, weil es darin um Liebe u Geschlechterverhältnisse ginge u das verboten sei als Lehrstoff an Unis.

Altmetric Explorer screenshot: Showing 5,011,088 mentions (from 4,918,333 individual posts) of research outputs from the results of your search query.

Since Jan 1 2025, which feels like four trillion years ago, research has been shared on here 5 million whole-ass times. Bluesky recently passed 2 billion posts IN TOTAL.

So 0.25% of the entire site's traffic was citations to research.

That is actually massively high. Is it? Yes. Here's why.

Humans have emitted 2750 gigatons of CO2 since the industrial revolution from burning fossil fuels and land use change. To put this in perspective, this is more than the (dry) mass of all living things on earth and everything humans have ever built combined:

Qianjiadong Reservoir in southern Hunan, China, produces a double harvest: solar energy and yellow carp. The solar farm produces up to 80 megawatts of power while the fish forage beneath the panels. With a massive scale-up of solar and wind at home and cheap exports of the technology, China is driving a worldwide surge of renewable energy—Science’s 2025 Breakthrough of the Year.

Science has named the seemingly unstoppable growth of renewable energy worldwide as the 2025 Breakthrough of the Year.

Scientists skip key US meetings — and seize on smaller alternatives Researchers are devising creative ways to get together as Trump’s policies curb travel to US gatherings.

Attendance at US-based science conferences is bouncing around this year but generally down. #AGU25 has ~10k fewer this year! I explored these trends for @nature.com — including solutions to keep conferences local & productive:

Improved modelling of biogenic emissions in human-disturbed forest edges and urban areas - Nature Communications GEE-MEGAN, a cloud-native MEGAN2.1 extension on Google Earth Engine, uses multisource satellite data to generate near-real-time BVOC emission estimates at 10–30 m resolution, refining emission charact...

Real-time estimates of #BVOC emissions with high resolution (10-30m) using #GEE-MEGAN model, which combines satellite data on land cover and vegetation. A great tool for studying the impacts of BVOCs in a rapidly urbanizing, warming world.
