An extreme early-season heat wave could see temperatures 20-30 degrees above average and record temperatures broken by 10 or more degrees today and tomorrow across the Desert Southwest. Jumping right into summer-like heat puts vulnerable populations at risk. Stay cool at www.weather.gov/safety/heat

♨️This week: a prolonged heat wave will push temperatures 20-30°F above normal across much of the western U.S. 🌡️Dozens of daily and all-time March records expected...including the earliest 100°F temps on record. A short 🧵

New co-authored open access @discover.springernature.com paper on a cool pavement pilot project in Tucson and its impact on pedestrian-level heat stress. link.springer.com/article/10.1... #uarizona #uazresearch #extremeheat #heatresilience #coolpavement

The seasonal anomalousness, as well sheer spatial extent, of upcoming record-shattering Western U.S. heatwave is genuinely startling. This will be associated with, by far, the strongest ridge ever observed during (at least) any Nov-Mar month. #CAwx #AZwx #NMwx #NVwx #UTwx #COwx

All signs continue to point to an exceptional, long-duration, and record-breaking to (in some cases) record-shattering March heatwave initially centered across U.S. Southwest but expanding to much broader region next week. This is effectively a full-on summer heatwave in March.

This will set back American science for a generation or more and put our national security at risk. www.nytimes.com/2026/03/13/c... #science #climatescience #ncar

Major heatwave heading to the Southwest next week - Tucson could see it's first 100°F almost a month earlier than the previous record set last year. #extremeheat #climatechange

"There's not any other city in the US that's doing a continual heat summit like this with the range of partners that we have, so I think that's something to be really proud of. That said, of course, we still have a lot more work to do which is why we're all here." news.arizona.edu/news/souther...

"Whether or not Americans know it, research at the center has contributed to enormous advances in the weather forecasts they consult each day." www.theatlantic.com/science/2025... #ncar #climatescience

It's difficult to convey how much harm dismantling NCAR would inflict on the U.S. scientific enterprise and our global leadership in climate science. www.usatoday.com/story/news/p... #climatescience #climatechange #ncar

NCAR is quite literally our global mothership. Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources. Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet. Unbelievable.

@who.int calls for protection of public health excellence in the US CDC

Common theme of people I've interviewed recently. At universities, in research centers, in diplomacy, in the legal system, dealing with refugees or immigrants: The reality inside is much worse than you would think from the outside.

Sharing my @uarizona.bsky.social TEDx Talk about how the world is currently experiencing a "heatshed" moment and we need more research and action on heat mitigation, heat management, and heat governance to advance equitable heat resilience. youtu.be/U8RErIjDWWc #heatresilience #extremeheat
