Atmospheric scientists have analyzed how the February near-total shutdown of mobility affected the air over China. Results show a striking drop in nitrogen oxides, a gas that comes mainly from tailpipes and is one component of smog. Learning how behavior shifts due to the COVID-19 pandemic affect air quality is of immediate importance, since the virus attacks human lungs. The event is also a way for Earth scientists to study how the atmosphere responds to sudden changes in emissions.

Social inequalities, specifically racism and classism, are impacting the biodiversity, evolutionary shifts and ecological health of plants and animals in our cities. That’s the main finding of a review paper led by the University of Washington, with co-authors at the University of California, Berkeley, and University of Michigan, which examined more than 170 published studies and analyzed the influence of systemic inequalities on ecology and evolution.

In a first-of-its-kind study published in Nature, scientists report on the conservation status of reef shark populations worldwide. The results are grim; reef sharks have become rare at numerous locations that used to be prime habitat, and in some cases sharks may be absent altogether. A long history of human exploitation is the culprit, with depleted shark populations strongly tied to socio-economic conditions, lack of governance and the proximity of reef environments to large human population centers.

It’s summertime, and that means scientists across the University of Washington College of the Environment are in the field collecting data. Researchers in the School of Oceanography are no different and are working off the Oregon coast on their annual expedition to maintain the long-running cabled ocean observatory. Part of the broader National Science Foundation’s Ocean Observatories Initiative (OOI), UW oversees the Regional Cabled Observatory that spans several sites in Pacific Northwest waters, ranging from shallow coastal locales to deeper waters in the open ocean more than 300 miles offshore.
