Weird pockets of intense heat today in the #Boulder CO area. FWIW, my car thermometer spiked from 103F to 108F across just a few blocks! Official high (COOP station, NOAA/NIST site) was 104F. That breaks the city's Aug record from 1936 by 2F and ties the all-time high set in 1954 (6/23 + 7/11).
Climate change never ignites a fire. That’s almost always humans or lightning. But it’s clear when we examine the data that climate heating sets the table for fires that burn faster and larger. Since the 1980s temperatures during fire season in the Pacific NW have warmed around 4°F… 1/
On 8/03 #HeatwaveKoch continued as a dangerous CAT3 over the West + will last through the week. Koch was also making inroads back into Texas. My criteria: guyonclimate.com/2026/05/11/e @michaelemann.bsky.social @katharinehayhoe.com @doctorvive.bsky.social @bhensonweather.bsky.social @zacklabe.com

I'm not sure folks have realized just how crazy the second half of 2026 and 2027 will be for global temperatures – on the back of a record-smashing El Niño event. Here is my latest estimate of where both years will end up compared to global temperatures since 1850.
At 1pm PT on Mon, Aug 3, I'll have a live update on the historic wildfire disaster that unfolded over the weekend in Spokane, Washington, including causes and context, then discuss the very active wildfire conditions currently present elsewhere in West.

Urban firestorms like the one that devastated Spokane Saturday have been growing more common because of increased development in the Wildland Urban Interface (WUI) and climate change. In this post, I document 9 such fires since 2016 in the U.S. yaleclimateconnections.org/2026/08/urba...

Climate change, combined with development in high-risk areas, is making urban wildfires more likely.

Well, it's official...Denver just hit 90° for the 28th time this month, setting a new record for most 90-degree days for any month on record. Old record: 27 days (July 1964 + 2012). #COwx
July 2026 was the second warmest July on record for the Contiguous U.S. It finished slightly warmer than July 2012 and slightly cooler than July 1936. As a reminder 1936 was an overall cool year. 🔥

With a a major El Niño now in full swing, global sea surface temperatures are approaching their previous record, set in March 2024 pulse.climate.copernicus.eu
Bordeaux, France, has now recorded more days above 40°C in 2026 alone than during the entire 105-year period from 1920 (when observations began) to 2025. This is deeply shocking.
