I submitted this short film to the 2025 Polar Film Festival to express some of the experiences we had during our time on Devon Island this past summer. The Canadian High Arctic is evocative and remarkable, and I'm so grateful to have spent that time in Nunavut! www.youtube.com/watch?v=PtoS...

Happy new water-year! Welcome to hydrological 2027!

Here'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. Originally presented to @cmos-scmo.bsky.social. www.youtube.com/watch?v=cWRE...

From 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...

Can't wait to chat mountains & climate & water & math at EGU in two weeks!

A shattered record is categorically different than a broken record, with the recent US heatwave the latest in a series of record-shattering extremes. A few of my thoughts on heat, water, and the face of climate change for @theglobeandmail.com: www.theglobeandmail.com/gift/0cdc78b...

It turns out that 2021 wasn't a warning; it was a promise.

Awful. 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...

I can't believe we're doing this again, but...we're doing this again. Another day of record-shattering Match heat across interior West & Central U.S., w/countless March (& even some April) monthly records broken. Some locations are even breaking monthly records set...last week.

Exactly 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.

Spring 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...

Fun 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!

Today's Climate Shift Index (CSI) is highlighting just how much climate change has made today's heat wave more likely to occur, especially for the warm nighttime temperatures. Follow along with real-time and forecast CSI global maps from @climatecentral.org at csi.climatecentral.org/climate-shif...

I spend most of my time thinking and writing and researching about heat waves. Being in one reminds me why -- extreme heat cuts deep.

Huge congratulations to @lucymaloney.bsky.social @onecityvan.bsky.social and @seanorr.bsky.social @copevancouver.bsky.social! Vancouver’s two new City Councillors!! 🥳

do you or someone you know work at noaa and are dealing with the AWS contract debacle? i'd love to talk to you :) signal mollytaft.76, you can speak anonymously

From #TDOV last year: "For the same reasons that trans people celebrate trans visibility .. so too do anti-trans actors fear it for awakening another person who questions or challenges the traditional heteronormative, sexist, racist version of capitalism we live in." xtramagazine.com/power/identi...

On cascading extremes in climate and politics, through my experiences in the Canadian High Arctic last summer. Check out my latest in The Globe and Mail here: www.theglobeandmail.com/gift/0cdc78b...

Today 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. 🇨🇦

Canada standing strong 🍁🇨🇦

After becoming increasingly enmeshed in the wildfire world, you start to notice things about the way we've systematically altered our relationship with the natural environment in a way that has increased the risk of destructive fires. And then you stop being able to unsee them.

Hi! 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 ❄️🔥💧☀️

Hydrology Paper of the Day @sam-science.bsky.social on how extreme temperature events affect hydrology, streamflow, and glacier ablation in the context of climate change: British Columbia and Alberta, Canada; CNN-LSTM machine learning; and numerical experiments to explore processes and sensitivities

Heatwaves aren't always dry -- and it turns out that the precipitation characteristics of North American heatwaves vary strongly in space and time. Come learn more at the Global Environmental Change online poster session at AGU! #climatechange #earthscience #heatwave #AGU24

Water 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.

Ice-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."

*waiting intensifies*

Hi BlueSky! To introduce -- I'm Sam 👋 I love rivers 💧 I love glaciers 🧊 I do not love climate change 🥵 I do not love heatwaves 🔥 In my postdoc I'm thinking about how all of the above interact 🤔 #hydrology #earth-science
