This week, I started my university-sanctioned quiet quitting program (phased retirement). Looking forward to continuing to do things that I enjoy — and fewer of those that I don’t — over the next few years.

Smoky conditions with moderate haze make me wonder if that's what the sky would look like on every "blue sky" day if geoengineering via solar radiation management were to take place. Here's a simulation for a clear day with 4 W/m^2 of cooling via sulfate aerosols. Source: simulatesrm.github.io

Smoke from these western fires, combined with those in Ontario and Minnesota, will be making the skies across much of eastern North America very hazy in the next few days. Smoke-related air quality will mostly be ok in the east.

Unfortunately, and as anticipated, yesterday's widespread lightning-following-heat event amid severe drought has sparked a large number of additional wildfires, expanding existing outbreak across OR, WA, & BC. Numerous heat signatures & large smoke plumes are evident. #ORwx #WAwx

New paper out! Using tree rings, fire records, Landsat biomass data, and SEMs, we show that atmospheric dryness acts as a coordinating driver of boreal forest dynamics, raising questions about the extent to which growth gains can offset increasing fire-driven biomass losses doi.org/10.1071/WF25...

Atmospheric dryness as a coordinated driver of fire activity and biomass accumulation in northwestern boreal Canada

Rising vapor pressure deficit in northwestern boreal Canada is linked to increased burned area and reduced tree growth, with indirect effects on biomass ac

$4 billion in direct economic losses in Michigan, $5 billion in NY, and $2 billion in WI from the past week of wildfire smoke, from things like outdoor work cancelled, tourism loss, etc. This doesn’t count health costs, which will be billions more. www.detroitnews.com/story/busine...

Smoke costs Michigan more than $4 billion in losses, analysis finds

The smoke that blanketed Michigan last week cost the state $4 billion in direct economic losses, a new report finds, as events and work shut down.

Wise words from the North. I would add that an insistence on a history of infrequent, stand-replacing fires is as colonial in Southern California as it is in the boreal forest. It’s insisting the land was empty when, in fact, people lived and burned throughout a varied, abundant cultural landscape.

Let's do some Canadian pipeline-wildfire math. The Canadian Energy Center says growing oil exports by 1.5M barrels/day **could** boost GDP by ~31B annually. Meanwhile, wildfire smoke health costs alone - just the health costs, nothing else - averaged 23B/year, past tense. And they're growing fast.

Are environmentalists right to warn against air conditioning? My take in The i Paper: cooling is a how-question, not a whether-question. Air-con runs hardest exactly when solar generates most. A grid ready for mass heat pump uptake can also absorb summer cooling. inews.co.uk/news/science...

Environmentalists say you shouldn’t have air-con. This is why they’re wrong

Air-con has a reputation of being bad for the climate, but its impact is negligible
