Updated data from NASA GISTEMP came in. The first half of 2026 was the 3rd warmest on record, June was the 2nd warmest on record. With the onset of El Niño it's certainly in the realm of possibilities that 2026 will end up as the warmest on record.

Today marks 139 years since the maximum temperature record of 33.3°C was set in Ireland in 1887 at Kilkenny Castle. We got very close yesterday, with a couple stations reaching 32°C. You can read the in-depth analysis of how the record was verified in the International Journal of Climatology

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.
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....
