@compoundnet.bsky.social's new "State of the Science" mini-blog series: a fully human summary of recent advances & current frontiers for compound events, hopefully of special value for ECRs. The first edition, on heat & humidity extremes, is live at bit.ly/4buNAL6. Many thx @afsribeiro.bsky.social!

Heat and Humidity Extremes (covering years 2023-26)

State of the Science Blog by Colin Raymond (UCLA) The last few years have seen considerable progress toward identifying the atmospheric processes that control the most intense humid-heat episodes1,…

The next Risk KAN Compound Events webinar will take place on Tuesday 7 July 8 am UTC. Ben Hague (@bhcoastal.bsky.social) will give a presentation on compound flooding in Australian estuaries under climate change. For meeting info: groups.google.com/u/1/g/riskka... or message @cassro314.bsky.social

Which compound weather and climate events mattered most in 2025? In a new report in @natrevearthenviron.nature.com we've taken a systematic global view to survey these events and their impacts across 5 typologies. rdcu.be/fmeAh We hope it proves useful for looking back on 'the year that was'...

My resignation letter

Incredibly, even *more* locations across U.S. are today experiencing their warmest March temperatures on record--many by a wide margin, with some even breaking April records. This includes most or all of: AZ, UT, CO, NM, WY, NE, KS, MO, IA, plus portions of many other states. 🫠

After the US admin cancelled the $B Climate + Weather Disaster dataset, @climatecentral.org hired the scientists who ran it and set it back up. Now the 2025 numbers are in: it's 3rd highest year on record and highest year w/o land-falling hurricanes. More: www.climatecentral.org/climate-serv...

What do we talk about when we talk about unprecedentedness? Without a clear baseline, understanding & preparedness for climate extremes may be out of whack. We sought to improve this for humid heat in our new paper out now in @aguadvances.bsky.social: agupubs.onlinelibrary.wiley.com/doi/10.1029/...

I recently had the pleasure of appearing on @urgentfutures.bsky.social for a meticulous, wide-ranging conversation about heat hazards, risks, and potential actions. Many thanks to host Jesse Damiani for the invitation and adroit questions! www.realitystudies.co/p/understand...

Multiple model ensembles are already suggesting a broad region of record mid-tropospheric ridging over the far NE Pacific and Washington/British Columbia, with possible record-breaking late-season warmth in the same region. That's a very strong signal ~1 week out. #WAwx #ORwx #BCwx

Engrossing meeting of the minds at the workshop this week. Nine creative yet plausible storylines were developed and a whole range of new cxns made. Thanks again to all who attended, and especially those who made it happen. We're excited to see what this format & these ideas can catalyze!

There is a new CLIVAR working group focused on climate risk (I'm one of the organizers). We are having our first public webinar tomorrow 7/10 at 1 pm ET. We have some FANTASTIC speakers including @kellyhereid.bsky.social, @climatefran.bsky.social, and Zong-Liang Yang.

It's often assumed that the best approach for climate applications is to select the best models, downscale them, and compute statistics of interest. In fact, in new work led by Adrienne Wootten, we find the downscaling process scrambles the meaning of 'best'...
