Dr. Sam Anderson @sam-science.bsky.social · 04/06/2026Here's (a short snippet of) the story of the forgotten heatwave of 1941 -- what happened, how it was different from modern extremes, and why it matters.

Dr. Sam Anderson @sam-science.bsky.social · 28/05/2026From the US in March to Europe in May, this is what the bleeding edge of climate change feels like. It isn't just a sign of things to come -- it's what climate change *is*. www.theglobeandmail.com/opinion/arti...theglobeandmail.comOpinion: Heat waves are invisible. But we need to see them for what they areA heatwave has shattered records in the U.S. When that happens, we have to confront the dramatic, terrifying change they signal – no matter where they’re happening 053

Dr. Sam Anderson @sam-science.bsky.social · 03/04/2026A shattered record is categorically different than a broken record, with the recent US heatwave the latest in a series of record-shattering extremes.

Conditions just continue to worsen for Colorado's snowpack (and across many other western U.S. states), with average snow water equivalent nosediving after the historic March heatwave. (which actually continues today with more record heat!) Graphic: nwcc-apps.sc.egov.usda.gov/awdb/basin-p... 19399132

Dr. Sam Anderson @sam-science.bsky.social · 23/03/2026Exactly why non-summer heatwaves matter so profoundly for water resources, especially in mountain regions where even small deviations in temperature drive large changes in where, where, and how much melt occurs. 063
Dr. Sam Anderson @sam-science.bsky.social · 23/03/2026Spring heatwaves drive enhanced early-season melt, raise risks of freshet flooding, and -- once they end -- leave basins parched as they face the impending summer. This is one type of non-summer heatwave that has outsized impacts on water resources! www.kqed.org/science/2000...kqed.org‘Snow-Eater’ Heat Wave Behind Big Sierra Melt Is a Look at Our Climate Future | KQEDAn early spring California heat wave is feasting on what’s left of the Sierra Nevada snowpack, raising wildfire and drought concerns. 032

Dr. Sam Anderson @sam-science.bsky.social · 05/03/2026Fun update! My postdoc is continuing in partnership between @sfuscience.bsky.social and Northwest Hydraulic Consultants here in Vancouver, where I will continue to better understand the ever evolving links between climate extremes and the water we live with. Exciting updates to come! 2090663
Dr. Sam Anderson @sam-science.bsky.social · 19/08/2025Heatwaves can be dry, or wet, or dry-then-wet, or wet-then-dry, or wet-then-dry-then-wet, or...

Dr. Sam Anderson @sam-science.bsky.social · 23/06/2025I spend most of my time thinking and writing and researching about heat waves. Being in one reminds me why -- extreme heat cuts deep. 040
Dr. Sam Anderson @sam-science.bsky.social · 05/05/2025✨ Archive newspapers teach us about the social and physical impacts of historical climate extremes ✨ Last week at @egu.eu I presented my recent work in which I use archived newspapers across North America in addition to climate reanalysis data to reconstruct "the lost heatwave" of 1941. 160

Dr. Sam Anderson @sam-science.bsky.social · 05/02/2025Today I learned that the southernmost point of Nunavut -- Stag Island -- is deep in James Bay. This means that Nunavut extends further west than Alberta, further east than New Brunswick, near the North Pole, and further south than Edmonton. The geography of this country is amazing. 🇨🇦 080

Dr. Sam Anderson @sam-science.bsky.social · 14/01/2025Hi! An introduction to my new followers: 1. I research how heatwaves impact rivers and water systems 2. I got into climate science because I love glaciers and snow, and I think it's nice when we have water to drink 3. I write about climate, water, and us ❄️🔥💧☀️ 051

Dr. Sam Anderson @sam-science.bsky.social · 09/02/2024Water management links local and federal interests. Federalism -- through finance, policy, and geography -- has long been key to reshaping the water landscape in Alberta. Here are some of my thoughts for The Globe and Mail at a moment of jurisdictional crossroads in the Prairies.theglobeandmail.comOpinion: Our federation helped make Alberta rich in water. Now, that dam is breakingAlbertans seeking sovereignty forget that the province’s agricultural success is a gift of pan-governmental cooperation – something they can’t lose sight of, in the face of serious water shortages 000

Dr. Sam Anderson @sam-science.bsky.social · 05/10/2023Ice-wedge polygons in the Arctic reshape the landscape and its functioning -- perhaps surprisingly, Canadian cities have behaved in a similar way. A fun piece to write and think about, but the main point is: "we would do well to see ourselves in once-frozen lands: perhaps then we will finally act."theconversation.comHow Arctic landscapes and Canadian cityscapes share a similar patternWhile a seemingly remote and unfamiliar landscape, the Arctic shares many surprising similarities with contemporary Canadian cityscapes. 020
