Wildfire emissions in 2025 reach records for Europe and Canada The Copernicus Atmosphere Monitoring Service (CAMS) has reported that global wildfire emissions from January to November 2025 reached around 1,380 megatonnes

Residents complain of excessive smoke from Whitehorse fuel break work | CBC News Yukon wildfire officials says they're installing more air quality monitors in areas south of downtown Whitehorse, as some local residents complain about excessive smoke in the area.

It was great fun to make this animation for NiCHE! They were my first environmental history community back in my U of T days and it was a delight and privilege to return their kindness with a nifty map. #envhist #envhum #gischat #cdnhist #histgeog

Amid climate impacts, leading Secwépemc firekeeper shares 'a better way of looking after the land' In a time of worsening wildfires, Joe Gilchrist says cultural burning 'needs to be multiplied hundreds of times' — returning to Indigenous stewardship

Animating the Archive: The Geography of NiCHE Posts since 2004 While NiCHE began as a Canadian environmental history network, its subject matter has always been situated in an international context, fostering conversations and collaborations across borders.

Today our editor, @micaamy.bsky.social, unveils a map made by Geoffrey Wallace that visualizes the geography of NiCHE blog posts going back to 2004.

Cumulative effects of fire in the Fraser River basin on freshwater quality and implications for the Salish Sea The movement of water from land to the ocean serves as a major biogeochemical link between terrestrial and marine systems, through which terrestrial d…

I may have shared this article before, but I was thinking about it again over the weekend so here it is again. Open access (👏) science showing 16.3% variance in water quality in the Fraser River basin due to fire. #wildfire firehttps://www.sciencedirect.com/science/article/pii/S0048969725010538

I learned so much this summer from so many people, and now it's time to take a rest. Looking forward to a winter of learning and working hard to make things better in the small ways I can.

you know academia is truly a dumpster fire when a policy paper is behind such a pricy paywall that the policy professionals its allegedly aimed at at don't have enough budget to access it. Good job everyone keep up the good work.

Here's the message I'm getting.

This morning when I opened up NASA FIRMS to check for heat signatures, I recieved an error message that stated that information was no longer being regularly updated due to federal funding constraints. Has anyone else sees this? Any additional info? #wildfire

Wildfire smoke will kill nearly 1.4m each year by end of century if emissions not curbed – study A separate research found that at the current rate of global heating, more than 70,000 people will die in the US by 2050

The Gaurdian is really on a wildfire smoke kick, and I'm here for it. www.theguardian.com/us-news/2025...

Delighted that this work continues to find new audiences, and (although purely coincidental) feels very appropriate coming out on the last day of my last fire season deployment. Thank you for hosting me, and for the work of your wonderful editorial team @envhistnow.bsky.social !

Pine...uh....finds a way

Smoke from Canada’s wildfires killed nine-year-old Carter Vigh – and 82,000 others around the world Toxic particles spewed by 2023’s wildfires were even responsible for 22,000 early deaths in Europe, researchers say

The impacts of wildfire smoke (and climate change generally) can be amorphous and hard to trace, but here the Guardian has accomplished a story that pins them to the page. www.theguardian.com/environment/...

I can't take my eyes off these fires in the west of the Cariboo region. Its the summer that won't end out there, despite COLD overnight temperatures and shortening days. Look at this one chugging through a cutblock -- open flame visible from satellite (sept 7).

I haven't had much cause to bust out my corsi-rosenthal box yet this summer, but today its making short work of the 160 AQI outside (currently 15 in my office).

definitely not, since its in northern BC, Canada.

The thing that always blows my mind with the satellite imagery is that we can't even see the head of the fire, since its usually concealed by smoke. Copernicus' false colour (urban) shows that, as impressive as the previous image may be, the head of the fire is burning even hotter and faster.

Sentinel 2 captured some truly unhinged fire behaviour yesterday. When you can see an organized flame front from space, its safe to say that our fire behaviour is "aggressive."

Also from August 30 -- Sentinel captured the plume coming up from SS104 burning near Fort Provenance, NWT, as it punched up into the atmosphere.

Watching smoke from space is one thing -- watching fire is another. This is a capture from Aug 30, and is of the fire burning north of Tsacha Lake in BC. Flames are visible from Sentinel's passover -- you can see them burning in the patch of green in the top left.

A recovering academic moment of realization today: I'm developing a new course for my organization and not only am I getting paid to write the content but I have access to a team of 3 subject matter experts and am working directly with an adult learning professional. Academia, take notes.

Yes, I did post this same picture a few minutes ago with the wrong ID 🫠

Quantifying the short-term mortality effects of wildfire smoke in Europe: a multicountry epidemiological study in 654 contiguous regions Associations with all-cause and cause-specific mortality were larger for fire-related compared with non-fire-related PM2·5.

Wildfire smoke is more deadly than other sources of PM 2.5. I originally read about this study in the Guardian today, but here's the original paper.
