In April 2025, I recorded 41 fatal landslides that cost 107 lives. I’m somewhat behind with posting updates on global fatal landslides due to other workload pressures – please accept my apologies. Please be assured that I’m still collecting the data and that I will make a summary available as soon as I can. Somewhat […]

Proposed NOAA Budget Calls for $0 for Climate Research
In the latest move in a months-long attack on climate science funding, the Trump administration released a budget document on 30 June that calls for zero funding for climate research and the elimination of a slew of NOAA services, including the agency’s climate laboratories, regional climate data efforts, tornado and severe storm research, and partnerships with other institutions.
Un antiguo evento de calentamiento podría haber durado más de lo que pensábamos
Una nueva investigación sobre el Máximo Térmico del Paleoceno-Eoceno usó análisis probabilístico para entender mejor su duración y sobre cuánto tiempo podría afectar el calentamiento moderno al ciclo del carbono.
Landslides during periods of glacial retreat in Alaska
An excellent new paper (Walden et al. 2025) examines the occurrence of accelerated movement in rock slope landslides in Alaska as adjacent glaciers melt. The exceptional temperatures in recent days in both North America and Europe has once again highlighted the rate at which the climate is changing in response to anthropogenic increases in greenhouse […]
Precipitation Extremes Drive Swings in Lake Tahoe’s UV Exposure
An 18-year study reveals dramatic year-to-year variations in ultraviolet radiation penetration tied to Sierra Nevada precipitation cycles.
Water Tracks: The Veins of Thawing Landscapes
Tracing and tracking change in permafrost flowpaths could reveal the dynamics of warming poles.
Finding Consensus on Arctic Ocean Climate History
Understanding the effects of a “blue” Arctic Ocean on future climate requires a coordinated effort to study Earth’s past warm periods using a variety of classical and cutting-edge methods.
What’s Changed—and What Hasn’t—Since the EPA’s Endangerment Finding
A scientist-authored brief played a role in the 2009 determination that greenhouse gases endanger public health. With the finding now up for reconsideration, the same scientists revisit their opinion.
Coverage Factors Affect Urban CO2 Monitoring from Space
Orbital mechanics and environmental factors limiting the ability of Orbiting Carbon Observatory missions to collect data in space and time affect city-level monitoring, reporting, and verification goals.
NOAA’s Climate Website May Soon Shut Down
Climate.gov, NOAA’s portal to the work of their Climate Program Office, will likely soon shut down as most of the staff charged with maintaining it were fired on 31 May.
