Extreme heat is preferentially killing young adults and small children, finds a new study on mortality in Mexico by @Columbia PhD candidate @DannyBressler1 and colleagues from @columbiaclimate, @Stanford, @montanastate, @UCLA, @BU_Tweets, @todoscicese: news.climate.columbia.edu/20…

Risk KAN: Compound Events webinars are continuing! Next is Fri Nov 8 at 3pm UTC with @froeltho speaking about "Compound marine heatwaves and biogeochemical extremes: Drivers, changes and impacts". Zoom info: columbiauniversity.zoom.us/j…
No matter how intense the humid heat, it might be thought that sunset and a refreshing sea breeze will always bring some relief. But close examination of the Persian/Arabian Gulf region dispels these assumptions, as explored in our new @CommsEarth paper: rdcu.be/dWXl5
Metrics (WBGT, UTCI) with radiation have a typical afternoon peak. But Tw & HI, widely discussed in recent years, apply well to indoor/shaded conditions. We consider them incomplete yet valuable signposts on the way toward a full, locally relevant portrait of heat-stress risk.
@NWSPhoenix's streak of consecutive record-setting days, already 13, would reach 20 if the current forecast holds. Among all global locations with 50+ years of data, the only comparable streaks have been on various tropical Pacific islands, plus the Russia 2010 mega heat wave.
Helene's aftermath is rightly drawing much of the attention in the US, but the ongoing heat wave in Phoenix is truly shaping up to be one for the record books. Today was the 7th consecutive record-tying or -setting max temp, with nearly all the next 7 days expected to do the same
Urbanization + extreme weather + climate change = probably time to move the Arizona State Fair to a cooler month

🆕Special Webinar | In one month, XAIDA and @CLINTH2020 will be holding a webinar on compound weather and climate events.
Meet our two speakers, @Bevacqua_E (UFZ) and Niklas Luther (JLU).

🗓️October 25th ⏰10:30am (CEST)
Insightful reporting by @abcnews about efforts at @HeatHealth_USYD to probe the very limits of human heat tolerance. (With a hot/dry wet-bulb temp of 35C, this trial had to be ended after 2.5 hours.) abc.net.au/news/2024-09-02/d…
Encouraging to now see humid heat spotlighted in the 2023 State of the Climate report climate.gov/news-features/un…, but alarming to track its inexorable rise.
Great work summarizing this hazard in our subsection led by Kate Willett
Well-designed and immersive training school in a beautiful setting! Highly recommended if you'd like to become more involved in the CE community
Applications for the 3rd Como Training School on Compound Events are open!
Deadline for applications: August 25th.

A fundamental problem in humid heat -- as a bivariate quantity, what does it mean if places or times have the same humid-heat value (choose your favorite metric) but different combinations of temperature and moisture?
In the vein of "what can't be measured can't be managed", we hope stickiness can be used as a tool to more readily describe and interpret humid heat's complexities (spatially, diurnally, seasonally, interannually) and their meaning for impacts.
And also see Casey's thread for her take! xitter.cf/ccivanovich/status/179… The paper is at journals.ametsoc.org/view/jo…
In what is likely the peak of my scientific career, we created a new variable!
If you’ve ever struggled to quantify the different drivers of extreme humid heat, take a look at our new article on “stickiness” in @AMS_atmos 🧵1/9
