Heat-related mortality risk is widespread across Washington state, study shows
Heat-related deaths occur across Washington state, even in regions with typically milder climates. This is the most extensive study yet of heat-related mortality in Washington state, and the first to look beyond the major population to and include rural areas. Researchers used statistical methods to uncover “hidden” deaths that may have listed something else, like illness or a chronic disease, as the primary cause.

Deepest scientific ocean drilling effort sheds light on Japan’s next ‘big one’
A 2018 expedition that drilled farther into the seafloor than ever before — almost 2 miles — sought to take measurements of stress as close as possible to a tectonic fault off the coast of Japan. Surprisingly, the researchers found little built-up tectonic stress. The findings could help to better understand earthquakes in subduction zones around the world.

‘Dangerous’ and ‘extremely dangerous’ heat stress to become more common by 2100
A new study projects the number of days with “dangerous” and “extremely dangerous” mixtures of heat and humidity by the end of this century. Even if global warming is limited to 2 degrees Celsius, results show that deadly heat waves will become much more common in the mid-latitudes, and many tropical regions will experience “dangerous” heat for about half the year.

New study calculates retreat of glacier edges in Alaska’s Kenai Fjords National Park
As glaciers worldwide retreat due to climate change, managers of national parks need to know what’s on the horizon to prepare for the future. A new study from the University of Washington and the National Park Service measures 38 years of change for glaciers in Kenai Fjords National Park south of Anchorage. The study, published Aug. 5 in The Journal of Glaciology, finds that 13 of the 19 glaciers show substantial retreat, four are relatively stable, and two have advanced. It also finds trends in which glacier types are disappearing fastest.

‘Safety in numbers’ tactic keeps Pacific salmon safe from predators
A new University of Washington study that leverages historical data has found unique support for a “safety in numbers” hypothesis by showing that Pacific salmon in larger groups have lower risk of being eaten by predators. But for some salmon species, schooling comes at the cost of competition for food, and those fish may trade safety for a meal.

Including all types of emissions shortens timeline to reach Paris Agreement temperature targets
Looking beyond CO2 to include other human-generated pollutants increases the amount of warming that humans have already committed to by past emissions. Earth will continue to warm even if all emissions cease, and the planet is committed to reaching peak temperatures about five to 10 years before experiencing them.

Solar energy explains fast yearly retreat of Antarctica’s sea ice
Sea ice around Antarctica retreats more quickly than it advances, an asymmetry that has been a puzzle. New analysis shows that the Southern Hemisphere is following simple rules of physics, as peak midsummer sun causes rapid changes. In this respect, it seems, it’s Arctic sea ice that is more mysterious.

Moon jellies appear to be gobbling up zooplankton in Puget Sound
University of Washington-led research suggests moon jellies are feasting on zooplankton, the various tiny animals that drift with the currents, in the bays they inhabit. This could affect other hungry marine life, like juvenile salmon or herring — especially if predictions are correct and climate change will favor fast-growing jellyfish.

eDNA a useful tool for early detection of invasive green crab
As the green crab invasion in the state worsens, a new analysis method developed by University of Washington and Washington Sea Grant scientists could help contain future invasions and prevent new outbreaks using water testing and genetic analysis. The results show that the DNA-based technique works as well in detecting the presence of green crabs as setting traps to catch the live animals, which is a more laborious process. Results suggest these two methods could complement each other as approaches to learn where the species’ range is expanding.

Glaciers are squishy, holding slightly more ice than thought
Though usually though of as a solid, glaciers are also slightly compressible, or squishy. This compression over the huge expanse of an ice sheet — like Antarctica or Greenland — makes the overall ice sheet more dense and lowers the surface by tens of feet compared to what would otherwise be expected.

Bubbles of methane rising from seafloor in Puget Sound
The release of methane, a powerful greenhouse gas responsible for almost a quarter of global warming, is being studied around the world, from Arctic wetlands to livestock feedlots. A University of Washington team has discovered a source much closer to home: 349 plumes of methane gas bubbling up from the seafloor in Puget Sound, which holds more water than any other U.S. estuary.

Shifting ocean closures best way to protect animals from accidental catch
Many nations are calling for protection of 30% of the world’s oceans by 2030 from some or all types of exploitation, including fishing. Building off this proposal, a new analysis led by the University of Washington looks at how effective fishing closures are at reducing accidental catch. Researchers found that permanent marine protected areas are a relatively inefficient way to protect marine biodiversity that is accidentally caught in fisheries. Dynamic ocean management — changing the pattern of closures as accidental catch hotspots shift — is much more effective.
