CO₂ emissions vary across countries & continents, notes @laurencerouil.bsky.social, Director of the Copernicus Atmosphere Monitoring Service. Europe’s emissions have declined over the past decade, but in our shared global atmosphere, CO₂ concentrations continue to rise. More in #GCH2025 ⬇

See Earth’s atmosphere like never before! The first images from MTG-S1's Infrared Sounder (IRS) were unveiled today at the #EuropeanSpaceConf, revealing storms, moisture flows and temperature patterns in striking detail - a preview of the near real-time weather and #climate data to come. (cont. 🧵)

#Chile has declared a state of catastrophe as #wildfires killed already 18 people. The #Copernicus #Sentinel5P Aerosol Index map shows a huge smoke plume of more than 1200 km, fueled by strong winds and extreme heat. #ClimateEmergency #incendioforestales

This week’s featured image shows smoke plumes rising from wildfires near Concepción, Chile, captured on 18 Jan by Sentinel-3. 🔥 Fires across the Ñuble and Biobío regions have burned more than 8,500 hectares (21,000 acres). Hot, dry, and windy conditions have accelerated the spread: bit.ly/4qYFbVo

🔴⚠️🔥♨️🇨🇱More than 50000 evacuated, 19 deaths and more than 8500Ha already burned in the #Biobio & #Nuble : #Chile is suffering high temperatures and strong winds that are currently boosting 32 #wildfires.⬇️#Sentinel3 view with active fires on Jan.18 #incendio #climatemergency

Floods are one of the most devastating hazards for society. This chapter, as part of the @iahs-aish.bsky.social Panta Rhei Book, explores the interlinkages of this "natural" hazard as human-flood systems www.sciencedirect.com/science/chap...

Canada's worst wildfire season produced so much smoke that it spilled across national borders. A group of UMD researchers discovered that chemical compounds from the wildfires remained in the atmosphere months after the smoke subsided.
