It follows the people making those choices now. It treats climate anxiety as a reasonable response to real conditions. It won't tell you what to do, but it shows the tradeoffs clearly.

Rain in the Bridger Range above Bozeman, midwinter, where snowpack is supposed to stay dry and cold and light underfoot. Across the inland West, avalanche forecasters are probing snowpits and finding layers their training never prepared them for. Smooth. Hard. Wrong. ### Western Mountain Dashboard By late March, the Western mountains are supposed to be holding billions of gallons in snowpack. Frozen savings accounts for the cities, farms, salmon runs, and hydropower turbines that draw on them through summer and fall. Here's what's actually up there this week: record lows across multiple basins, March temperatures that belong in June, and forecasts being revised in directions nobody wanted. Six data points from the mountain West as it stands right now. No analysis, no projections about what it all means downstream. Just the numbers, the records, and the early outlooks. - **Oregon's Snowpack Just Set a Record Nobody Wanted** — [Source]() — Published 2026-03-25 Tag: Snow Drought Statewide snow water equivalent bottomed at 2.9 inches in early February, nearly 30% below the previous record from 2015. Mid-March average: 29% of normal. Colorado, Arizona, and the Colorado River Basin are also reporting record-low snowpack this season. - **One Mountain Range, Two Opposite Avalanche Futures** — [Source]() — Published 2026-03-25 Tag: Cascade Divide University of Washington researchers found warming creates more avalanche-prone ice crusts in colder inland zones like Eastern Washington, Idaho, and Montana. The warmer maritime Cascades get slush instead of ice, potentially lowering risk. Same warming signal, split by a single ridgeline. - **479 Stations Broke March Records in Four Days** — [Source]() — Published 2026-03-25 Tag: Heat Records Four Arizona and California stations hit 112°F on March 20, a new all-time U.S. March record. Flagstaff reached 84°F, eleven degrees above any previous March day and four above any April day ever recorded there. Attribution analysis: virtually impossible without climate change. - **Less Snow Means Fire Season Starts Earlier** — [Source]() — Published 2026-03-25 Tag: Fire Outlook Washington Deputy Climatologist Karin Bumbaco: when snowpack is this thin, it melts out sooner, widening the fire window. NOAA forecasts drought persisting across the West through June, with new drought developing in areas currently drought-free. - **Yakima Farmers Told to Expect 44% Allocation** — [Source]() — Published 2026-03-25 Tag: Water Supply Bureau of Reclamation projects junior water rights holders in the Yakima Basin will receive 44% of normal supply. Fields that grow hops, cherries, and apples will go fallow or unplanted. Lake Powell's most probable forecast hits minimum hydropower elevation by December. - **It Rained Plenty. The Snow Still Disappeared.** — [Source]() — Published 2026-03-25 Tag: Drought Expansion Northern Idaho is experiencing its first large-scale "wet snow drought": near-normal precipitation falling as rain instead of snow. Oregon's November-through-February temperatures tied 1934 as warmest on record. The Deschutes, Yakima, and Rio Grande basins continue deteriorating. ### New Research - **Higher Temperatures Lead to More Melt-Freeze Crusts in Snowpacks in Cooler Regions of the Pacific Northwest** — [Source]() — Published 2026-03-25 Alden et al. document how warming creates buried ice crusts in Pacific Northwest snowpacks, producing weak layers that collapse under new snow. Warmer winters don't just reduce snowpack. They make what remains more dangerous to move through. Where is this hitting? Cooler, higher-elevation zones previously considered stable. The mountains that felt safe are developing the hazard profiles of riskier terrain. Want the full picture? Our feature this week traces the ice-crust mechanism from lab to ridgeline, and into the lives it's reshaping. - **Intensifying Global Heat Threatens Livability for Younger and Older Adults** — [Source]() — Published 2026-03-25 Hours of outdoor heat too extreme for routine activity have doubled worldwide since the 1950s. For adults over 65, roughly 900 hours a year now exceed the threshold where even light tasks in shade become physiologically unsafe. The study, from ASU's Jennifer Vanos and The Nature Conservancy's Luke Parsons, measures what aging bodies can actually do in heat, not just whether they survive it. Why does 900 hours matter? That's more than every weekend of the year. For older adults, outdoor life is being quietly foreclosed, hour by hour. What about younger people? Even under-40s now face roughly 50 unsafe hours annually, a number that barely existed two generations ago. - **Global Gridded Dataset of Heating and Cooling Degree Days Under Climate Change Scenarios** — [Source]() — Published 2026-03-25 At 2°C warming, 3.79 billion people will live with extreme heat by 2050, up from 23% of the global population in 2010 to 41%. Oxford's Dr. Jesus Lizana and colleagues found the sharpest adaptation pressure arrives before 1.5°C, meaning cooling infrastructure is an immediate need, not a future line item. Where's the surprise? Hot days double in Austria and Canada at 2°C. Ireland sees a 230% surge. Cold-climate nations are building for a planet that no longer exists. How short is the window? Most heat-driven cooling demand materializes before 1.5°C, ahead of nearly every national planning cycle now in place. - **Global Warming Has Accelerated Significantly** — [Source]() — Published 2026-03-25 After stripping out El Niño, volcanic, and solar noise, Potsdam Institute physicists Grant Foster and Stefan Rahmstorf detected a near-doubling in the underlying warming rate since 2015, to roughly 0.35°C per decade across all five major temperature datasets. If the pace holds, 1.5°C falls before 2030. Some climate scientists, including Michael Mann, argue recent spikes reflect temporary factors, not structural acceleration. What compresses? Every adaptation timeline pegged to a later 1.5°C breach. Infrastructure plans, insurance models, municipal budgets, all calibrated to a slower clock. Is the debate settled? No. Mann and others see El Niño and reduced aerosol pollution, not a permanent shift. The disagreement itself is the planning problem. - **Beyond Temperature: A Cultural Contexts Approach to Heat and Health** — [Source]() — Published 2026-03-25 Extreme heat already kills more Americans each year than hurricanes, floods, and tornadoes combined. This Vanderbilt/Robert Wood Johnson Foundation/WHO report argues those deaths track housing quality, labor conditions, and cooling access more than temperature itself. In Maricopa County, homeless residents are 100 times more likely to die of heat. Virtually all heat deaths, the authors conclude, are preventable social failures. Who dies? Not a random cross-section. People without housing, without cooling, without the option to stop working. The thermometer is the least of it. How preventable? Nearly entirely, the report argues. Heat mortality is produced by how people are housed and employed, not simply by how hot it gets. ### Downstream Cascade - [When the Snowpack Vanishes, Everything Downstream Breaks]() — Published 2026-03-25 Oregon's snowpack hit the zero percentile in February. Not low. The lowest ever measured. Across the Columbia Basin, snow water equivalent sits at the second percentile, and peak snowpack has already passed. The deficit is unrecoverable. ### Further Reading - **Climate change may complicate avalanche risk across the Pacific Northwest** — [Source]() — Published 2026-03-25 UW study finds warming pushes dangerous ice crusts into inland zones whose forecasters have never managed them. - **Oregon's record low snowpack is not likely to recover, scientists say** — [Source]() — Published 2026-03-25 Central Oregon irrigators haven't received full water allotments since 2018.
