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.

This is the conclusion that I hope we will draw from the Zillow drama... that we need a gold-standard national data source for property-level risk to climate hazards that is transparent, accessible, and legally defensible. Private companies can help build it but the public needs to own it.

Last year, @michaelfwehner.bsky.social and Jim Kossin made the scientific case for a Cat6 cyclone. This week, Hurricane Melissa became the 6th storm in recorded history to smash through that threshold, with max winds of 216mph. And conditions leading to these storms are on the rise. Read more:

Truly being “pro-family” means ensuring access and cost of care - including IVF - never stands in the way of someone choosing to start or grow their family. Trump breaking his promise about something as important as this might not be surprising, but it is cruel.

For the people in the back

Just got to the fluoride episode of Parks and Rec in our rewatch and I'm still dumbfounded we're actually living it now.

One of the main goals of shade is to get us out of the sun and cool us down. And while that can make us feel better on a hot day, it can also be important for our health.

Yeah, it's August in the Southwest - but it's not supposed to be THIS hot. Some all-time records this week - and BTW, of the top 25 hottest Aug afternoons in PHX, 23 have been since 2000. A trend, perhaps? For a deep dive on the SW heatwave and Western drought/fire danger: tinyurl.com/mtj8bhc9

Getting down to brass tacks: We won't solve our flood issues without better land-use planning. I spoke with Bayliss Wagner from the Austin American-Statesman about the root causes of risk in many Texas (and American) communities. www.statesman.com/story/news/l...

Another death knell to soft diplomacy. What is the downside to allowing 13 to 16 year olds entry into the U.S.? Yes, let's create a generation of American-hating kids rather than allowing them to experience sports competition that can build comradery and compassion toward others around the world.

Why does risky coastal real estate keep selling despite rising seas, flooding, and insurance chaos? It’s not just denial — it's debt, disaster aid, and disconnection. New from me: open.substack.com/pub/susanpcr...

Are we great again

Federal regulators repeatedly granted appeals to remove Camp Mystic's buildings from their 100-year flood map, loosening oversight as the camp operated and expanded in a dangerous flood plain.

In light of the devastating Texas floods, it's relevant that the Trump admin recently clawed back nearly $900 million in grant funding already promised but not yet disbursed to states for improvements to stormwater systems and building flood control systems. www.motherjones.com/politics/202...

How can we cut the Gordian knot of flood risk in places with fast growth and little appetite for regulation? www.texastribune.org/2025/07/09/t...

“the weather in Texas was 7% wetter on July 4 than it was before climate change warmed that part of the state, and natural variability alone cannot explain this very exceptional meteorological condition.” www.propublica.org/article/texa...
