YouTube video by PBS Terra When Will Extreme Heat Become Unlivable?

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.

Schematic presented by Casey Ivanovich @ccivanovich.bsky.social during @wclivestream.bsky on May 28, 2025. "Explore how the land surface influences the tradeoffs between temperature and moisture to affect both dry and humid heat extremes." Schematics has the following labels next to images representing each: "solar insolation, large-scale circulation, precipitation, cloudiness, advection, urbanization, evapotranspiration, deforestation/land use change, proximity to water bodies, and irrigation."Text for questions also displayed, " How is this linked to heat seasonality?" and "How are humans altering these balances?"

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”

feeling toasty? @ccivanovich.bsky.social is about to talk heat waves and stickiness on the 100-hour @wclivestream.bsky.social wclivestream.com/watch

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.

Meet @ccivanovich.bsky.social, NASAGISS postdoc & Lamont-Doherty Earth Observatory PhD, who studies climate extremes & humid heat, including their physical & social drivers, and is also passionate about relaying complex scientific concepts to the public. #IDWGS ➡️ lamont.columbia.edu/news/women-s...

📣New Review!

Mortality impacts of the most extreme heat events

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 disproportionately kills young people: Evidence from wet-bulb temperature in Mexico Analysis of temperature exposure and microdata finds the majority of heat-related deaths are among people under 35 years old.

Important and well-researched work from @rdbressler.bsky.social, @ccivanovich.bsky.social, @regclimo.bsky.social amongst many others on the author list.

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!

Afterwards, make sure to swing by poster A53H-2194 presented by Ana Nunes that afternoon on our set of collaborations about extreme weather in Brazilian megacities!

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!

Welcome to all the Bluesky newbies! We've created a starter pack of compound events and multi hazard researchers and groups. Please send through suggestions for who else to add to the list

Casey points to the results of her dissertation chapter on a presentation slide during her defense.

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!
