Warming oceans have decimated marine parasites — but that’s not a good thing

jar with fish inside

Save the … parasites? Analyzing 140 years of parasite abundance in fish shows dramatic declines, especially in parasites that rely on three or more host species. The decline is linked to warming ocean temperatures. Parasitic species might be in real danger, researchers warn — and that means not just fewer worms, but losses for the entire ecosystem.

The strongest Arctic cyclone ever observed struck in January 2022. A new analysis led by the University of Washington shows that while forecasts accurately predicted the massive storm, models seriously underestimated its impact on sea ice. Results suggest how forecast models for a changing Arctic Ocean could improve.

Study reveals how ancient fish colonized the deep sea

A new University of Washington-led study 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 instead of shallow ocean waters that are warm and full of resources.


Permanent daylight saving time would reduce deer-vehicle collisions, study shows

University of Washington researchers found that adopting permanent daylight saving time in the United States would reduce deer-vehicle collisions and likely prevent an estimated 36,550 deer deaths, 33 human deaths, 2,054 human injuries and $1.19 billion in costs each year. Deer-vehicle collisions would decrease under permanent DST because skies would be brighter later into the evening.

Study suggests La Niña winters could keep on coming

snowy scene with bare trees

Forecasters are predicting a “three-peat La Niña” this year. This will be the third winter in a row that the Pacific Ocean has been in a La Niña cycle, something that’s happened only twice before in records going back to 1950. A new study of temperature patterns in the tropical Pacific Ocean suggests that climate change is, in the short term, favoring La Niñas.

Heat-related mortality risk is widespread across Washington state, study shows

W in sunshine

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’

White ship seen from below

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

maps of globe colored orange and red

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

fish swim together in a fish tank

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

Smokestacks and cooling towers for power plants

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

pinkish-white jelly on green background

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.

Farms following soil-friendly practices grow healthier food, study suggests

An experiment conducted on 10 farms across the U.S. suggests that crops from farms following soil-friendly practices for at least five years have a healthier nutritional profile than the same crops grown on neighboring, conventional farms. Researchers believe soil microbes and fungi boost certain beneficial minerals, vitamins and phytochemicals in the crops.

eDNA a useful tool for early detection of invasive green crab

green crab in the mud

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

three people walking on glacier

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.
