🌳 Trees affected by extreme heat produce fewer leaves and grow more slowly for up to two years afterwards. WMO-@fao.org in their latest joint report explore the science behind extreme heat, its impact on agriculture and how to build resilient agrifood systems. 📘 bit.ly/49pZUuZ

What effect does climate change have on wildfires, and how do wildfires affect the climate? Ammodo Science spoke with Guido van der Werf, professor of Landscape Fires and Carbon Cycle at Wageningen University & Research 👉 shorturl.at/5Bnoa #climatechange #wildfires #science #EduSky #AcademicSky🧪

🔥 Why doesn't Canada put out every wildfire? Sometimes monitoring beats fighting — fire is part of the boreal ecosystem. GWC Charter Member @mikeflannigan.bsky.social weighs in. #wildfire www.cleveland.com/metro/2026/0...

🔥Track global wildfire emissions in near-real time or look back at events since 2003. As fires burn worldwide, the “Fire Emissions Watch” app from #CopernicusAtmosphere provides fire emissions data & smoke plume forecasts based on Global Fire Assimilation System dataset. ⬇️

Hydroclimatic Rebound Drives Extreme Fire in California's Non‐Forested Ecosystems

Hydroclimatic rebound occurs when unusually wet periods are followed by intense drying, or vice versa, creating sharp moisture swings. We show that this process drives extreme fire activity in Califo...

“We have no need for air-conditioning, and so we don’t have filtration in the homes for smoke.” Project Lead Sue Natali and Sr. Arctic Lead Edward Alexander spoke to the New York Times about how the presence of smoke in northern communities is a growing cause for concern. #Canada #Arctic 🎁 link:

🔥 Emissions from Spain and Portugal #wildfires so far this year account for three quarters of 2025 total fire emissions for the European Union + United Kingdom based on #CopernicusAtmosphere data. As of 25 August, EU+UK emissions are the highest annual total in the GFAS dataset going back to 2003.

“The amount of spring rain is one of the best indicators of when you’ll hit the more severe part of the fire season,” Max Moritz @ucanr.edu said. “But the warming trend still plays a role because... plants are drying faster than in the past.” www.independent.com/2025/08/18/f...

Fire Season Is Starting Earlier Thanks to Climate Change, New Study Finds

Study co-authored by a UC Santa Barbara professor sheds light on timing, size, and speed of recent wildfires, including the Gifford Fire.

The EUBURN-SILEX campaign has just ended after a dozen flights over 🇫🇷 fires and 🇨🇦 plumes transported over the 🇫🇷 country. A comprehensive database was acquired using a set of innovative ✈️ in-situ and remote sensing instruments. Next phase is the postprocessing of the database acquired. 🔥 #EUBURN

New paper out - Regional wildfire smoke reduces boreal forest carbon uptake iopscience.iop.org/article/10.1... Wildfires are a source of carbon and they can reduce the carbon sink from the forest. Cumulative Net Ecosystem Exchange (NEE) shows a big drop in 2011 Day 138 due to wildfire smoke.

It's official. 2025 is now the third worst wildfire year on record in Canada. A study from 2018 examining fire-regime changes in Canada over the prior 57 years showed the fire season had been starting approximately one week earlier and ending one week later. Probably longer now.
