Happy Monday, Boulder. Hope you had a restful and rejuvenating weekend.

This morning’s top story from Tim Drugan explores an increase in nighttime fire intensity amid accelerating climate change, as outlined in a study published by CU’s Earth Lab. He spoke to local experts about shifting our thinking on the conventional wisdom of fire patterns, with the devastating Marshall Fire “portending things to come.”

Plus a celebration service for the late Clela Rorex, today’s police town hall, upcoming arts festivals, tonight’s Concerts in the Parks performance and more.

See you on Wednesday! ✌️

Night is no longer a respite from wildfire as the Marshall Fire showed, ‘portending things to come.’ What can be done to prepare for the next blaze?

By Tim Drugan

Historically, the fall of dusk has subdued fire. As the sun no longer warms the earth and temperatures stabilize, winds that hitherto brought flames an endless supply of oxygen are reduced to breezes that don’t so much fan fire as periodically cause grunts and shiftings in its slumber.

In recent years, however, nighttime temperatures have not been dropping as they once did, and the increase in humidity that usually accompanies cooler temps has become similarly absent. This creates conditions that encourage flames to sally forth on quests begun in daylight.

“You now have 24-hour fires,” said Adam Mahood, a former post-doc at CU Boulder’s Earth Lab who recently began another post-doc at the USDA Agricultural Research Service in Fort Collins. “You don’t get that break you used to.”

Such were the findings published by Mahood and colleagues this year in Nature, one of the premier science journals. The study, “Warming weakens the night-time barrier to global fire,” found, among other things, that nighttime fires have increased in intensity by 7.2 percent between 2003 and 2020. But as is often the case, science merely confirmed what those in the field were already wary of. 

“Firefighters know this is happening,” Mahood said. “We’re just documenting it and looking at the data.”

Brian Oliver, Boulder Fire-Rescue’s Wildland Chief, said that on a smaller scale it’s harder to see broad trends, though some recent fires have certainly adhered to data shown in the study. “There are plenty of times when conditions don’t moderate at night,” Oliver said. “The Marshall Fire is a good example. But the NCAR Fire, that first night things did calm down quite a bit. The second night we got some intensity but we were already in the mop-up phase.”

Oliver noted that the recent fire near Wonderland Lake on June 17 continued to burn with vigor through the night due to high fuel loads and humidity remaining low.

What We’re Reading

📖 Can Colorado Dems hold onto their advantage in the legislature? “The Colorado Senate is likely where Republicans have their best shot this year of taking back some control of state government from Democrats after four years in the minority of the legislative and executive branches. While the GOP will try to win a majority in the Colorado House and unseat Democratic Gov. Jared Polis, the odds are stacked against them in those two arenas. That leaves the 35-member Senate as the most plausible place to turn the tide.” [Colorado Sun]

📖 Boulder teams up with students to research history of park names: Boulder Parks and Recreation Department (BPR) worked with 70 undergraduate and graduate students at CU Boulder’s Department of History to research the history behind 82 park names and the stories behind them. “The purpose was to find missing stories and see how they reflect the community’s values…BPR plans to continue studying park names to ensure they reflect the city’s” Racial Equity Plan. [CPR]

📖 Inside Denver’s new safe-camping pallet shelters: “Crafted by Pallet, a company in Washington state, the shelter is made of pre-fabricated panels that are fairly easy to put together in an hour or two. The resulting structure can harbor people after natural disasters, as well as individuals experiencing homelessness. The one that I stayed in had a vaulted nine-foot ceiling, four windows, a bed with a mattress and a door that locked. It also had an air conditioner, a heater, a light and electrical outlets.” [Westword]


🏪 Mental Health Partners restores hours at its 24/7 walk-in crisis center. Since February, the county’s only dedicated facility for people experiencing a mental health emergency has been closed on weekends. It’s now open around the clock, but the underlying staffing shortage that prompted the reduction in services remains, according to the nonprofit.

🥕 Facing supply chain snarls and increased demand, Boulder food banks are having trouble keeping shelves stocked. Here’s how to help. Local food assistance programs have fewer options for those in need this summer, and they’re turning to the community for relief.

🗳️ Louisville Mayor Ashley Stolzmann poised to win race for Boulder County commissioner. With the latest batch of Democratic primary votes showing Stolzmann ahead by a razor-thin, 68-vote margin, her opponent, Elaina Shively, has conceded.

🎆 A year later, riot on Boulder’s University Hill spurs recommendations for stricter anti-noise ordinance and other measures. The University Hill Revitalization Working Group was tasked by the previous Boulder City Council with improving ‘quality of life’ on the Hill after a party-turned-riot damaged vehicles, led to arrests and reignited long-running tensions between local homeowners and students.
