MIT Technology Review Narrated Why climate researchers are taking the temperature of mountain snow
6 snips
Nov 19, 2025 Climate researchers are innovating ways to measure mountain snowpack temperatures, crucial for understanding water supply and flood risks. New infrared tools are being tested in the Sierra Nevada, where snow contributes significantly to California's water resources. The challenges of climate change demand better data as erratic weather patterns make forecasting more vital. Meanwhile, concerns grow over federal funding cuts jeopardizing monitoring programs. The podcast highlights groundbreaking techniques and stresses the global significance of accurate snow observations.

Episode notes
Field Test At Heavenly Ski Resort
- Dan McAvoy and Bjorn Bingham skied to a research plot at Heavenly to test a new infrared snow temperature device.
- They lowered the device down a snow hole and compared readings to traditional methods in the field.
Mount Rose Sampler Origins
- The Mount Rose Snow Sampler was invented to measure snow depth and water content for Lake Tahoe disputes.
- Its simple tube-and-scale method led to a federal snow survey program and ongoing SNOTEL development.
Cold Content Controls Melt Timing
- Snowpack temperature profiles reveal the cold content and energy needed to reach 32°F.
- Cold content determines whether the pack will resist or rapidly enter melt after warming or rain.
