Shoutout to Dmitri Kalashnikov, John Abatzoglou, Nicholas Nauslar, Daniel Swain, Danielle Touma and Deepti Singh for their fantastic study of California dry lightning patterns that helped with forecast confidence ahead of today’s lightning siege and associated wildfires.

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!

Researchers Are Resurrecting Billion-Dollar Disaster Tool Trump Killed Nonprofit Climate Central has hired the scientist behind a key database of costly weather disasters to rebuild it.

Scoop: The U.S. billion-dollar disaster database is set to return this fall over at @climatecentral.org. They've hired the former NOAA scientist who ran the project for 10+ years www.bloomberg.com/news/article...

Every country is warming.

Every country is experiencing more extreme weather events because of climate change, mainly caused by burning fossil fuels. www.ShowYourStripes.info

Time to #ShowYourStripes and start climate conversations to prompt actions to reduce emissions, personally & collectively.

DON'T use "fun in the sun" images for extreme heat stories.

DO use photos that convey the suffering and pain caused by extreme heat.

Extreme heat is the most deadly weather event in the US.
Images are critical pieces of any news story — they draw readers in and help to communicate the story itself. However, publications continue to publish photos that fail to convey the severity and danger of extreme heat.

Happening now! Tune-in.

Question from a livestream viewer: “How many lives are collectively impacted by [NOAA's] monitoring and rapid response work.”

John Cortinas: “I don’t have any exact numbers, but I would probably start by saying the entire population of the United States…"

Climate change continued to have unpredictable impacts on wildfire in 2024. Unexpected shifts, like the Americas producing 40% of C emissions (normally it's <25%), and anomalous events, like the fatal Feb '24 Chile fire or the Pantanal wetlands burning, occur more often.

I'm devastated and heartbroken. Staff at the U.S. Global Change Research Program (USGCRP) got the ax. Most likely means the Sixth National Climate Assessment (NCA6) is also cooked. USGCRP was the glue across the Federal family on all things climate - reducing duplication and making efficiencies.

Come join us this summer in Portland, OR for a workshop on compounding and cascading risks.

Workshop flyer

One sent tsunami alerts. Another flew with 'hurricane hunters.' Both were just fired from NOAA. The Trump administration last week cut about 600 workers at NOAA and the National Weather Service.

This is a really good article that clearly connects the firing of hazard scientists to the ability of emergency managers to be able to do their jobs.

I don’t think a lot of people outside science understand the symbiotic relationship we have between public, private, and educational sectors. We all lean on each other for help, support, and R&D. In most cases, we aren’t competing so much as all rowing different boats in the same direction.

U.S. early-career researchers struggling amid chaos Uncertain funding, government firings, and distressed universities hit vulnerable groups especially hard

This hurts new and early career investigators (like me) the hardest. Most of us finished our postdocs & started our labs during the COVID-19 pandemic with shutdowns and supply issues at that time. Now we’re being hit with ::all of this::

Statement begins: The mass firing of both new hires and recently promoted senior staff within NOAA, including mission-critical and life-saving roles at the National Weather Service (NWS), is profoundly alarming. It appears that NOAA staff fired today include meteorologists, data and computer scientists responsible for maintaining and upgrading weather predictive models, and technicians responsible for maintaining the nation’s weather instrumentation network (among many others). Housed within NOAA, the U.S. NWS is a truly world-class meteorological predictive service, perhaps singularly so. Its cost of operation is only ~$3-4/yr per taxpayer—equivalent to a single cup of coffee—and yields a truly remarkable return on investment (at least 10 to 1, and perhaps 100 to 1, depending on methods of estimation). NOAA and the NWS collectively offer tens to hundreds of billions of dollars each year in net economic benefit through a combination of averted losses and efficiencies gained....

I have written a short statement responding to mass firings today of #NOAA / National Weather Service (#NWS) staff (which were concentrated among recent hires as well as highly experienced staff who had recently been promoted). Please see below screenshot & below for full text.

Contributions of Atmospheric Ridging and Low Soil Moisture to the Record‐Breaking June 2023 Mexico‐Texas Heatwave A heatwave with record-breaking intensity, persistence, and spatial extent affected Mexico and Texas during June 2023 Circulation, record-low soil moisture, and their interaction explain most of ...

New work with Dimitr Kalashnikov, Deepti Singh (@climatechirper.bsky.social) and Mingfang Ting!

We demonstrate that record low soil moisture and global warming were major contributors to a record breaking heatwave in Mexico+Texas in 2023

A statement I must make:

Out today in @globalchangebio.bsky.social is our (brief!) rapid-response piece on the broader context surrounding the January 2025 Southern California wildfires & relevance of wet-to-dry hydroclimate whiplash to fire both locally and globally on a warming Earth. [1/8] onlinelibrary.wiley....

Thanks to @weatherwest.bsky.social for his leadership on this paper as well as his sustained efforts to inform communities, media, and fellow scientists. His extensive outreach during the current wildfire situation in LA and other disasters provides valuable and timely information to so many people!

Also from #NCA5:

"Climate change is leading to larger and more severe wildfires in the western US, bringing acute and chronic impacts both near and far from the flames. Wildfires have significant public health, socioeconomic, and ecological implications..."
