New study: 2021 heat wave created ‘perfect storm’ for shellfish die-off

Dead oysters seen along a shoreline in Washington state, following a record heat wave in summer 2021.

It’s hard to forget the excruciating heat that blanketed the Pacific Northwest in late June 2021. Temperatures in Oregon, Washington and British Columbia soared to well above 100 degrees Fahrenheit, with Seattle setting an all-time heat record of 108 degrees on June 28. During the heat wave, also called a heat dome, scientists and community members alike noticed a disturbing uptick of dying and dead shellfish on some beaches in Washington and British Columbia, both in the Salish Sea and along the outer coast.

Q&A: Healthier soil leads to more-nutritious food, argues new book by UW geomorphologist David Montgomery

Cover of the book, What Your Food Ate: How to Heal Our Land and Reclaim Our Health

During the pandemic lockdown, many people were dabbling in urban farming or growing houseplants. University of Washington geomorphologist David Montgomery was exploring a deeper topic: How do practices that rebuild soil health affect the quality of the food that comes from that soil? His new book, “What Your Food Ate,” released June 21 from W.W. Norton & Company and co-authored by Anne Biklé, explores this question.

Newly documented population of polar bears in Southeast Greenland sheds light on the species’ future in a warming Arctic

A Southeast Greenland polar bear on glacier, or freshwater, ice at 61 degrees north in September 2016.

Scientists have documented a previously unknown subpopulation of polar bears living in Southeast Greenland. The polar bears survive with limited access to sea ice by hunting from freshwater ice that pours into the ocean from Greenland’s glaciers. Because this isolated population is genetically distinct and uniquely adapted to its environment, studying it could shed light on the future of the species in a warming Arctic.

UW College of the Environment sophomore Jonathan Kwong awarded selective Udall Scholarship

University of Washington sophomore Jonathan Kwong was recently named a Udall Scholar, a selective honor awarded to 55 college sophomores and juniors for leadership, public service and commitment to issues related to American Indian nations or to the environment. More than 380 candidates from across the country applied for this selective scholarship, with award recipients receiving up to $7,000 each. The Udall Scholarship honors the legacies of Morris Udall and Stewart Udall, whose careers held significant impact on American Indian self-governance and stewardship of lands and resources.

UW, Seattle Public Library, Seattle Public Utilities collaboration uses VR goggles to visualize sea level rise in Seattle

The VR experience begins by explaining how gases like carbon dioxide create an invisible blanket around Earth, trapping solar radiation. The user can hold up a magnifying glass that makes Earth’s atmosphere appear blue. Later in the experience the narrator explains how glaciers in Antarctica, right, contribute to rising seas.

A new project uses virtual reality to help communicate what climate models are predicting: Greenhouse gas emissions are increasing Earth’s temperature, melting glaciers that could create many feet of global sea level rise by the end of this century. The Our Future Duwamish project, available to community groups through The Seattle Public Library, uses Oculus Quest 2 goggles to help viewers imagine rising seas from a vantage point along the South Seattle waterway.
