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...

Opinion: Heat waves are invisible. But we need to see them for what they are

A 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

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...

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.

Another coolwx.com map showing locations currently breaking temperature records. There are, once again, countless in the western and central U.S.

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.

Amid the historic and ongoing record heatwave (which will continue for at least another week in this region), Colorado River Basin snowpack has unfortunately taken an unprecedented March nosedive. Given the pre-existing water crisis, this is a highly alarming trajectory.

Screenshot of current Upper Colorado Basin snow water equivalent as of Mar 23. It is at a record low level for the date, by a wide margin, and the trajectory of the curve is strongly downward at extreme odds with every single other historical year in March. Via USDA NRCS.

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...

An early spring California heat wave is feasting on what’s left of the Sierra Nevada snowpack, raising wildfire and drought concerns.

Heatwaves can be dry, or wet, or dry-then-wet, or wet-then-dry, or wet-then-dry-then-wet, or... It all depends where you are and what season it is! Our new paper dives into the cool world of heatwaves and precipitation. doi.org/10.1088/3033... @ioppublishing.bsky.social @sfuscience.bsky.social

✨ 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.

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...

On an island carved by climate extremes, I came to better understand our own polarization

The fractures in our social and political fabrics are, in some ways, not unlike the landscape of Devon Island, in the High Arctic: torn open and deepened by extremity, unhidden and cascading

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. 🇨🇦

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 ❄️🔥💧☀️
