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!

With the Heat Wave expected across the Central and Eastern US this weekend into early next week, this was an excellent video primer on the Limit of Compensability for adults and associated Heat Risk. Great Job by @ccivanovich.bsky.social and the PBS Terra team youtu.be/7hBMbQ9de1g?...

Summer heat across the Eastern U.S. is off the charts in a new "stickiness" measurement that combines heat and humidity—and it isn’t over yet.

Casey Ivanovich @ccivanovich.bsky.social shared during @wclivestream.bsky.social the factors influencing dangerous extreme heat events plus ‬a public communication tip for conveying the difference between humid and dry heat extremes – “sticky” vs “crispy”

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.

At least we don't have to read about this on a federal government website:

At 2°C of warming, the area on Earth that is too hot for humans will triple. This is fine. 🔥🧪

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 👇

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 present my recent work deriving the new variable "stickiness" at #AGU24 next Friday -- stop by to learn more about our new tool to quantify the temperature versus humidity contributions to humid heat!

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!
