GFS map of temperature anomalies over the contiguous USA for March 21, 2026.

We need to talk a bit about how utterly absurd the March heatwave was in the USA.

This heatwave would have been impossible without a boost from climate change, but even with climate change it remains a deeply unlikely event.

A thread looking at some of the numbers.

Royal blue water with a black light sensor.

Measuring light with a hyper spectral sensor in the oligotrophic South Atlantic gyre on the #SUBSEA cruise with @schmidtocean.bsky.social . 1% of surface light remained at 132 meters deep. The bluest water I have ever seen.

This policy brief explores the opportunities and challenges of mainstreaming nature-based approaches across all economic sectors, highlighting the need to strengthen coordination and collaboration to achieve freshwater restoration.

The bass addition experiment covered in the paper could be an analog for predator invasion.
It seems risky to use a real invader. Maybe in some cases the target ecosystem can be isolated and reversibility can be guaranteed.

Official map from NOAA depicting the relative rank of winter 2025-2026 temperatures at a county level across the contiguous U.S. Many counties in the western and central U.S. are depicted in dark red color, signifying record-warmest winter. All other counties in the west and central U.S. are depicted in dark orange colors, signifying a "near record warm" rank.

The official NOAA stats out this week confirm that winter 2025-26 was the warmest on record across a huge portion of the western and central U.S., which has contributed to extremely low mountain snowpack & worsened the CO River crisis. Meanwhile, record March heat is in forecast.

At ~$1 billion/day, the US has spent as much on the war in Iran in ten days as the entire FY25 budget for the National Science Foundation ($10 billion).

Trump's FY26 budget request for the agency declined to $3.9 billion, due to a "realignment of resources in a constrained fiscal environment."

Iran's FM condemns US attack on Qeshm's freshwater desalination plant, warns of grave consequences US President Donald Trump announced that Iran promised not to attack its neighbours anymore

Multiple news outlets are reporting a US attack on an Iranian #desalination plant.
If verified, this violates international law protecting #water systems during wars, and it sets a dangerous precedent, given intense dependence of Gulf countries on desalination.
