Here is a Claude-assisted animation of the change of daily average temperatures from 1872 - current at the official Denver station. Note again the striking anomaly of the final year plotted (2026).

Another fun day of running with donkeys.

The Claude-assisted graphic here shows that the overall average temperature from Jan 1-Oct 23 (today) this year is hottest on record for the entire state of CO (top) and for Denver (bottom). The bottom figure goes back to the 1800s.

A bear family pictured here being herded toward me as I was coming down Bear peak by paparazzi following them. That was a tad unnerving since I was sort of cliffed out.

Must watch. youtu.be/yJyQXGynwsg?...

Truly spectacular and a bit horrifying. I really hope the track stays away from populated areas and/or weakens significantly before it hits land.

It may be excessive, but it would be nice to run this daily to better plan mountain outings during windy conditions, and to therefore know which part of the mountain is relatively calm near the surface.

Well, here we are again, needing to expand the y-axis range... this time for recent Niño 3.4 SST values. 😩 (There should be a blue dot at the end of the blue line showing the latest daily SST value. It's not visible because it's, well, off the chart.)

Some new snow on Arapaho Peak this morning, as seen from Erie.

The best climate change documentary I've ever reviewed — Weather Under Fire — needs donations to get completed. Check out my review and please contribute to the 501c3 charity to get this great film to the finish line: donate.mazloweb.com/donate/the-w... yaleclimateconnections.org/2026/10/weat...

Six years ago on this date, the historic Cameron Peak Fire of northern CO was on one of its more ferocious daily runs due to a windstorm. You can see here the wave cloud above the smoke plume associated with the flow responsible for wild fire behaviors. The view is from north Boulder.

CPC finally showing some maps for our region that are nice to look at.

What’s this weird sky water falling as a soaking mist in Boulder?!

To better understand the East Troublesome Fire of Oct 2020, @ncar-ral.bsky.social developed the AI models with fuel & @ncar-cisl.bsky.social Visualization & Analysis Platform (VAPOR) turned the fuel data into stunning 3-D renderings, which went on to win various visualization awards. bit.ly/3TOJgko

Classic mid-October weather. 🎃☕️

The normal October 10 temperatures at our Bayfield station are a low of 37 and a high of 55. With a low of 55.9 and a high of 88.5 so far…fair to say that today is above average.

We wanted to understand the AI proof of Hilbert’s Tenth Problem over the rationals. So we talked to three unvaccinated UFC fans at an Arby’s in Scranton.

On another day of record heat, I chose a running route through the heart of the Cameron Peak fire burn scar. Here is a doleful video of scenes to give a sense of the scale. But to not be completely bleak, I can share that outside the sterilized fire zones, there is a lot of young growth.

This semi-permanent autumn heatwave is getting much less attention than our historic March heatwave in CO, maybe because we’ve grown desensitized to it, but it is impressive. This morning, once again, our temps aren’t far below our normal high.

Drought-affected areas in Europe have expanded substantially in recent decades. ​ By the end of August 2026, meteorological drought affected around 46% of Europe, with 40% of the affected area under extreme drought, a much larger share than in 2025. See more: climate.copernicus.eu/european-sum...

Looks like a tree, but it's a supercilium cloud that I just saw

Eight years ago today 😭

Easily my favorite training run of this training cycle.

NYTimes: We sat down with 3 independent Erie, CO voters at the Old Mine cafe. After the ECMWF has failed to to deliver on precipitation on a regular basis, DOGE checks, and lower prices, they are willing to give yesterday's 12Z ECMWF forecast of rain in Erie another chance.

German chemist Dr. Ida Noddack co-discovered Rhenium (element 75) in 1925. She died #OTD in 1978. She was the first to propose the concept of nuclear fission (1934). Her theory was met with fierce skepticism and outright dismissed by contemporary physics giants. But 4 years later...🧵 #WomenInSTEM

Unbelievable footage from NOAA’s Hurricane Hunters inside the eye of Category 5 Hurricane Polo. Simply incredible.

The world has made real progress in steering away from some of the darkest climate futures where global emissions doubled (or more) this century. But as David Wallace-Wells and I note in today's NYT, we are not out of the woods yet, and climate uncertainty is not our friend: www.nytimes.com/2026...

Absolutely zero expectations of anything cool today and then I run across this

Reading my horoscope before I go into the office.

Some brilliant cloud textures illuminated by the sunrise this morning.
