Volcanic ash is a silent killer, more so than lava: What Alaska needs to know with Mount Spurr likely to erupt

When volcanoes like Alaska’s Mount Spurr erupt, the ash can damage people’s lungs, smother crops and kill animals, and the harm can continue to spread long afterward.

US earthquake safety relies on federal employees’ expertise

The US experiences violent earthquakes, but the damage and death toll is much lower than in many countries because of the work of federal seismologists and engineers.

Arctic Report Card 2023: From wildfires to melting sea ice, the warmest summer on record had cascading impacts across the Arctic

The early heat melted snow and warmed rivers, heating up the land and downstream ocean areas. The effects harmed salmon fisheries, melted sea ice and fueled widespread fires.

The world’s boreal forests may be shrinking as climate change pushes them northward

How will Earth’s vast boreal forests look in a warmer world? Combining satellite-based research with fieldwork shows that the planet’s largest wilderness may be changing in unexpected ways.
Permafrost and ice wedges have built up over millennia in the Arctic. When they thaw, they destabilize the surrounding landscape. Michael Robinson Chavez/The Washington Post via Getty Images

Thawing permafrost is roiling the Arctic landscape, driven by a hidden world of changes beneath the surface as the climate warms

Ground is collapsing and massive lakes are draining in a matter of days. Thawing permafrost is having profound effects on the region and its infrastructure.
