Inclusion, Diversity, Equity, and Accessibility: Excellent IDEA!

Inclusion, diversity, equity, and accessibility (IDEA) are recognized as central ethical commitments that strengthen science and expand its impact. However, their contribution to support continued innovation and the factual barriers and enablers are under-documented.

A new study from Naji and Reyes et al. [2026] addresses this gap. The authors conducted semi-structured interviews with underrepresented and underserved Earth observation professionals and identified challenges and support they received during their career. Through these conversations, they identify barriers and enablers and discuss solutions. The authors present interesting quotes from the interviews that excellently convey the feelings and discouragement caused by the barriers and the enthusiasm and scientific benefit stimulated by successful enablers. The article provides an illuminating perspective on the real value of IDEA for the benefit of science and humanity.

Storms and shifting sands—assessing the ocean's impact on Start Bay coastline in UK

Phys.org: Earth science - Wed, 02/18/2026 - 15:14
Experts have warned that extensive storm damage caused to one of South Devon's most iconic routes is likely to become more frequent as global sea levels rise and the impacts of extreme wave events increases. Members of the University of Plymouth's Coastal Processes Research Group have been conducting detailed measurements and visual assessments along Start Bay for the past 20 years.

Cracks in snow propagate faster than expected

Phys.org: Earth science - Wed, 02/18/2026 - 14:40
Since 10 January 2026, the WSL Institute for Snow and Avalanche Research (SLF) has received reports of hundreds of "whumpfs" (i.e., sounds indicating a collapse in the snowpack) and of remote triggering events—unmistakable signs of a critical avalanche situation involving a weak snowpack. A whumpf is where snow sports enthusiasts cause a fracture in a weak layer of the snow, which within seconds propagates as a crack across the terrain. If the crack reaches steep terrain, this may trigger an avalanche—a remote triggering event.
