“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...

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.

We got an exceedingly rare view of #pyrocumulus as they were forming above the fire. Scientists are studying the composition and physical properties of smoke to better understand its meteorological and climate impacts.

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.

🧪🛰️🔥🌍 It is that time of the year when satellite monitoring of fires and #smoke in S. America has to be more dedicated. Fires have been going already for a while (since May particularly in N. Argentina and Paraguay and increasing north with time) but none have been v. intense or putting much smoke.

Total column carbon monoxide (CO) from the TROPOMI sensor on the Sentinel 5-P satellite shows the tremendous emissions from ongoing Canadian wildfires, wrapping around a large Low pressure system yesterday 23 Jul. @esaearth.esa.int

If you're interested in the topic of using fire as a land management tool, both with prescribed fire and managed wildfire, check out this great new episode of Amanda Monthei's Life With Fire Podcast. lifewithfirepodcast.com/episodes/the...

🛰️🌬️🔥 Nice discussion here on how dust and thick smoke is detected from space using different spectral band combinations. satelliteliaisonblog.wordpress.com/2025/07/18/j...

New 🔥 pod from Arctic Council on decolonizing wildland fire management, revitalizing Indigenous fire practices, and how the global community can respond to an Arctic on fire. Grateful our @woodwellclimate.bsky.social team could join the conversation 🧵 #CanadaWildfires #ArcticFire #ClimateSolutions

🧪🛰️🔥 Massive #smoke cloud over #Canada this morning. For reference, the area of Greenland about 2.1M sq km too

Our new NPJ Natural Hazards article reveals how human action, extreme weather, and complex terrain combined to fuel Türkiye’s largest wildfire for the last century. #wildfire #climatechange #anthropocene #Türkiye 🔥👇 www.nature.com/articles/s44... @bikem.bsky.social @tolgagorum.bsky.social

#EUBURN had the opportunity to make detailed measurements of these long range transported 🇨🇦 smoke plumes from 17 to 19 july. We are studying how canadian wildfires 🔥 affect weather, climate and air quality across Europe. Plumes well observed 👀 from the research aircraft.

Manitoba is having a bad fire season in 2025 with over 300 fires burning over 1.25 M ha thus far. www.gov.mb.ca/conservation... Looks like there may be a rash of new lightning-caused fire starts with lots of lightning today and duff fuel moisture is very receptive to lightning starts.

Total estimated emissions from Canadian #wildfires continue to increase rapidly with 2025 already 3rd highest year, after 2023 & 2024, as of 13 July. #CopernicusAtmosphere GFAS data based on MODIS🛰️ active fire obs ads.atmosphere.copernicus.eu/datasets/cam... @copernicusecmwf.bsky.social @ecmwf.int

🔥The intensity of wildfires is projected to rise across 88% of global fire-prone areas under 1.5°C warming, with the largest increases expected in wildland-urban interfaces already prone to disasters @calxcunningham.bsky.social 👉Read more here: www.nature.com/articles/s43...

Abatzoglou (@climate-guy) et al show that extreme #fire years in global #forests align with rare fire #weather extremes. #ClimateChange has made such extremes 88-152% more probable, highlighting the need for urgent action for #adaptation and #mitigation of fire impacts www.nature.com/articles/s41...

The area burned in the Canadian 2025 fire season has hit 5 million ha. Third active fire season in a row that combined has burned 7% of the Canadian forest. Currently we have 346 fires out of control (192 monitored out of control (OC) and 154 OC that are being actioned) so expect the number to rise.

Another summer in the Pyrocene -- "As of July 9, fires in 2025 have charred 4.8 million hectares across Canada. That’s an area about twice the size of New Jersey and nearly four times the 25-year average." 🌍https://earthobservatory.nasa.gov/images/154531/manitoba-burning

Increase in total estimated emissions from Canadian #wildfires slowed through 2nd half of June but 2025 already a quite extreme year with continuing fires + two months of summer to come. #CopernicusAtmosphere GFAS data based on MODIS🛰️ active fire obs ads.atmosphere.copernicus.eu/datasets/cam...

2025 is an active fire season in Canada with 4.2 M ha burned, 401 active fires and more importantly 166 of those 401 fires are out of control. Lightning season is kicking into gear in Canada so expect more fires and more fire growth with hot, dry and windy conditions coming in the next few weeks.

📣Are you an ECR interested and working on topics around Atmospheric Chemistry? Then join the 2nd IGAC-iCACGP ECR 2025 online conference, which will be organized around 3 different time zones. Abstract until 10th of Aug. More details here: www.ecr-igac-icacgp.org/2025/03/05/i...

Researchers looked at 20 years of data and found that wildfire risk is highest in areas that are not too dry and not too wet. eos.org/research-spo...

Canada and Russia are experiencing intense early wildfire activity ahead of the boreal summer. CAMS is tracking smoke transport across vast distances, impacting atmospheric conditions as far away as Europe and the Arctic. Check out the full details atmosphere.copernicus.eu/cams-tracks-...

In 2024, wildfire carbon emissions from high northern latitudes registered sixth highest in the 22-year satellite record. Wildfire carbon emissions from the sub-Arctic and Arctic regions reached an estimated 151 million tonnes. #ESOTC2024 #C3S🔥 bit.ly/3XWrOJw

"'A global red alert' -- The destruction of the world’s forests reached the highest level ever recorded in 2024, losing an area the size of Italy to agriculture, fires, logging & mining, according to analysis from the University of Maryland." 🌏 www.theguardian.com/environment/...

Climate extremes are rising, but intact ecosystems can buffer their impacts. On #BiodiversityDay, we echo Mahecha et al. (2024): protecting nature is key to climate resilience.🌲 🔗 Read their #OpenAccess article: buff.ly/inNlQTo #AGUPubs #GlobalGoals #Biodiversity #STEM #SDGs #ClimateChange

The report from the [email protected] Fire UNcertainty in CHemistry Emissions, and Modelling (FUNCHEM) workshop last September can be found in the latest @igacproject.bsky.social newsletter (pp 10-13) igacproject.org/sites/defaul...

📣🔥 New wildfire study: Blazes that cross into neighborhoods are much more deadly than remote wildfires, according to a new study led by NSF NCAR. In fact, fires that burn in the wildland-urban interface are 3x more likely to cause annual premature deaths. Learn more: bit.ly/4hhsdwZ
