🌫️ Image of the Week: smoke & haze over Thailand, Laos, Myanmar & neighbouring countries, captured by #Copernicus Sentinel-3 on 14 Apr.
Driven by a mix of agricultural burning & wildfires - exacerbated by warm, dry conditions - has caused air quality impacts across the region. Visit: bit.ly/4tgZ5g1
Absolutely fantastic explainer on the quasi-geostrophic omega equation (and related aspects of atmospheric dynamics) from @roostweather.bsky.social 👏 www.youtube.com/watch?v=YmZi...
Spring is possibly the most complicated season in terms of air pollution. Read this article to find out why this is the case and how CAMS can help you track air pollution:

La France va de nouveau vivre des journées exceptionnelles avec des 30°C entrant dans le cercle très restreint des plus précoces jamais observés.

Excellent thread on one of the key advantages of using LLMs for all non-native English scientists / students that need to use this common language to proceed in their field of expertise.
🏜 Enorme zandstorm raasde gisteren door Afrika: het ging om een 1500 km lange 'muur' van zand en stof! Stofdeeltjes ervan kunnen tot 5-6 km hoogte worden geblazen. Hier komt ons verschijnsel 'Saharastof' vandaan, dat bij een zuidenwind over Europa kan waaien.

I just resigned from NASA. It breaks my heart to leave, but I’ve become convinced the best path forward is to do the best science I can, and that can’t be here anymore. I’m still in love with the promise of those four magic letters. Ad astra per aspera, and remember: Earth is the only good planet.
The current energy crisis might globally speed-up the energy transition in an unprecendented reduction in fossil fuel use. In eg India, SE Asia EV for cars and solar + batteries instead of unsteady petrol, gas en coal imports.
The production of ERA6, coming up in 2027, has started. The next‑generation climate reanalysis from #CopernicusClimate will offer >2× finer resolution than ERA5, a coupled ocean–atmosphere–wave model, improved data access & more.

The last 11 years have been the hottest years ever recorded. Earth’s energy imbalance has reached its highest than at any time in observed history, with heat reaching deeper into the ocean. This is the Global #StateOfClimate 2025.

The current energy crisis might globally speed-up the energy transition in an unprecendented reduction in fossil fuel use. In eg India, SE Asia EV for cars and solar + batteries instead of unsteady petrol, gas en coal imports.
Emission reductions through a decrease in the production of oil and gas might become relevant for mitigating climate warming, if maintained for years. Caused by unintended US (climate) policy..
The last LNG tankers from the Gulf arrive in the next 10 days. After that, many countries face a sharp drop in supply.
Qatar’s Ras Laffan plant — 20% of global LNG — could be offline for 3-5 years.
Reminder that fossil fuel import dependence is an energy security problem, not just a climate one.

Would be useful if someone would produce in near-real time monthly day/daytime and night cloud coverages from geostationary satellite observations to attribute the current SST anomaly to the likely cloud anomaly
Even without El Niño, Global Sea Surface Temperatures are already hitting daily record highs.
We're now entering a climate hotter than has existed for hundreds of thousands of years!
NEW | Electric vehicles avoided oil demand equivalent to 70% of #Iran’s exports in 2025 🚗⚡
Oil remains the Achilles’ heel of the global economy. But Ember’s latest analysis shows EVs are the most powerful tool to reduce that vulnerability.

Yes, see e.g. this study led by George Tselioudis (coauthor of a.o. the recent two Hansen et al. papers).
If climate sensitivity is higher, that should result in (relatively) more warming from both increasing greenhouse gases and decreasing aerosols.

Daily sea surface temperature for 3rd of March 2026 over the French coastal areas
For those who don’t know, marine heatwaves don’t just happen in summer, they can occur in winter too…
And what a winter it has been for French coastal waters. Let’s hope the water cools down before summer
I want to repeat comments I already made on this plot since some news outlets seem to ignore them: Hubble will not reenter until early 2030s. The curve here is alarming, but will flatten out as we hit solar minimum in the coming years. I still think it's time for NASA to take action on a reboost.
