The Weather & Climate Livestream is back to remind us all of the *huge* range of services provided by federally funded science! I'll be up far past my bedtime at 12:20am ET on Wed to talk about how extreme heat seasons are changing around the world -- tune in this week and write/call your reps!

A graphic on a blue background, with the title "Help Save Weather & Climate Science in the United States". 2 boxes beneath say "Watch the Livestream: Learn about federally funded weather and climate research + what's at risk!" and "Call Your Representatives: Share what you learned with your representatives: wclivestream.com/call". The bottom of the graphic says "50 hours for our future: Mon. Jun 1st - Wed. Jun 3rd".

Very excited to kick off #EGU26 with a solicited talk Monday morning! I'll be presenting my work on the emerging risk for heat extremes during unexpected times of year around the world. Stop by bright and early to learn more from this and other exciting presentations in this session!

Flyer with information for Casey's EGU26 presentation. Image has a banner at the top with blue to red contours. Underneath is the EGU26 General Assembly logo and Casey's headshot, name and affiliation (NASA Goddard Institute for Space Studies). A bolded presentation title reads "Global Extreme Heat Seasons Are Lengthening Asymmetrically." Next to a calendar icon is the presentation date (Monday, 04 May 2026), next to a clock icon is the time (08:35 - 08:55 CEST), and next to a location icon is the room number (Room N2). There is a QR code which links to the agenda at the following web page: https://meetingorganizer.copernicus.org/EGU26/EGU26-7630.html At the bottom of the flyer is the session title (Session NH1.9: Extreme heat: characterization, drivers, prediction and impacts in a warming climate).

Our paper exploring the drivers of the November 2023 “Taylor Swift” heatwave in Rio de Janeiro is officially out in WCD! Take a read to learn more about the causes of this record-breaking heatwave and Rio’s emerging risk for extreme heat: wcd.copernicus.org/articles/6/1...

Physical drivers of the November 2023 heatwave in Rio de Janeiro

Abstract. Because extreme heat has not historically been a major hazard for the city of Rio de Janeiro, the November 2023 Heatwave magnitude and timing were staggering. Here we conduct a case study of...

Tune in for the kick off of the livestream tomorrow (1pm ET) from NASA GISS during the final hours before we're removed from our office. I'll be speaking about the federally-funded work I've done over the past six years to help understand the drivers of extreme humid heat events.

Mark your calendars: starting 5/28, join us at wclivestream.com/watch as we kick off 💯 hours of meteorology and climate science, all with one goal: save America's forecasts! Whether it's tomorrow's rain, or the coastline in fifty years, our speakers want to keep helping you plan for your futures.

For extreme heat, each year seems to bring fresh examples of precedents being surpassed — in heat severity, but also in understanding of its physics and risks. A group of us led by Tom Matthews and Radley Horton have assembled a review of this knowledge whirlwind: www.nature.com/articles/s43...

Great paper from my brilliant climate scientist colleague @ccivanovich.bsky.social and economists @rdbressler.bsky.social @ajsw.info ! Great example also how we can improve climate impacts studies when incentives align to allow for this kind of interdisciplinary collaboration and design.

🚨"Heat disproportionally kills young people: Evidence from Wet-Bulb Temperature Exposure" My new paper co-lead with @ajsw.info is out today! Using 20 years of nationwide mortality microdata + wet-bulb temperature, we uncovered fascinating new findings. Thread 👇 www.science.org/doi/10.1126/...

Amazing to see this work dreamed up by Danny and I in the early years of our PhDs in its final form! By combining high resolution climate and mortality data, we paint a more complete picture of the evolving risk for temperature-related deaths in Mexico. Take a read!

Excited to share our recent paper led by Sophie Johnson on the relationship between sequential humid heat and precipitation events 🌡️☔ We identify where humid heat is associated with suppressed or enhanced rainfall, with implications for compound extremes! iopscience.iop.org/article/10.1...

Hi Bluesky! I’m a climate scientist researching the dynamics and impacts of extreme events, currently studying the physical drivers of extreme humid heat. I’m passionate about collaborating with interdisciplinary research teams and look forward to connecting with folks in climate and other fields!
