Stress-testing the Cascadia Subduction Zone reveals variability that could impact how earthquakes spread

A new University of Washington study examining 13 years of ground motion data from sites near the Cascadia Subduction Zone shows that the entirety of the fault may not be as tightly locked as researchers thought, which could change our understanding of how a big earthquake might hit the Pacific Northwest. ESS Associate Professor Marine Denolle is a co-author.

Snowball Earth: Why the planet stayed frozen for 56 million years

A new study led by ESS graduate student and planetary scientist Trent Thomas finds intensified seafloor weathering was the decisive factor that allowed one planet-wide ice age to last 56 million years. This result overturns a long-standing assumption that carbon vented from volcanoes controls the duration of Snowball Earth glaciations. Thomas is interviewed.

UW glaciologist Eric Steig featured in CBS Sunday Morning segment on American history and climate change

UW glaciologist and ESS Professor Eric Steig was interviewed on the February 15th CBS Sunday Morning show. In the segment, "These United States: George Washington and climate change", Steig showed CBS Environmental correspondent David Schechter around his lab (Δ*IsoLab, the isotope geochemistry laboratory in the Department of Earth and Space Sciences, which he co-leads with other ESS and Atmospheric Sciences faculty). Together they looked at an ice core dating back to 1776, at the start of the American Revolution.

The dirt on dirt: Flood recovery starts from the ground up for Washington farmers

The road to recovery for Washington farmers following last month's widespread flooding includes cleaning up and replacing their soil. "You can think of healthy, fertile soils as the foundation that keeps civilization afloat," ESS Professor David Montgomery is quoted. Large-scale flooding can not only wash away these healthy, fertile soils, but it can also bring in undesirable additions such as plastic, oil, and roadway runoff.
