I’ve been thinking — and worrying — about climate change for a long time. In 1980, I came to the University of Washington to pursue a PhD, wrestling with the problem of detecting the fingerprint of human impact on the climate system. The topic held sway with my colleagues but had no traction with the general public. All that has changed, and that change is now visible in many ways across the globe.

Research from the University of Washington shows that signals from the upper atmosphere could improve tsunami forecasting and, someday, help track ash plumes and other impacts after a volcanic eruption. A new study analyzed the Hunga Tonga-Hunga Ha’apai eruption in the South Pacific earlier this year. The Jan. 15, 2022, volcanic eruption was the largest to be recorded by modern equipment.

University of Washington geologists had set out to create computer-based field experiences long before the COVID-19 pandemic hit. Juliet Crider, a UW associate professor of Earth and space sciences, first got a grant from the National Science Foundation to send a former graduate student and a drone to photograph an iconic Pennsylvania geological site and pilot a new approach to field geology.

A warming climate is causing a decline in sea ice in the Arctic Ocean, where loss of sea ice has important ecological, economic and climate impacts. On top of this long-term shift due to climate change are weather events that affect the sea ice from week to week. The strongest Arctic cyclone ever observed poleward of 70 degrees north latitude struck in January 2022 northeast of Greenland.

The deep sea contains more than 90% of the water in our oceans, but only about a third of all fish species. Scientists have long thought the explanation for this was intuitive — shallow ocean waters are warm and full of resources, making them a prime location for new species to evolve and thrive. But a new University of Washington study led by Elizabeth Miller reports that throughout Earth’s ancient history, there were several periods of time when many fish actually favored the cold, dark, barren waters of the deep sea.
