91探花 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.
A new 91探花-led study has found that even in remote, rarely visited national parks, the presence of even just a few humans impacts the activity of wildlife that live there. Nearly any level of human activity in a protected area like a national park can alter the behavior of animals there.
Forecasters are predicting a 鈥渢hree-peat La Ni帽a鈥� this year. This will be the third winter in a row that the Pacific Ocean has been in a La Ni帽a cycle, something that鈥檚 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 Ni帽as.
Shuyi Chen, a 91探花professor of atmospheric sciences, was traveling to a conference in Boston as Hurricane Ian approached the Gulf of Mexico. During breaks at the conference, she provided her thoughts on the closely watched catastrophic storm system that made landfall in Florida on Sept. 28. Q: What are your thoughts on Hurricane Ian? How does it compare to other storms? See also: “UW鈥檚 Shuyi Chen on hurricane science, forecasting and the 2017 hurricane season“ Shuyi Chen: Each hurricane…
Researchers dropped technology developed at the 91探花 off the coast of Florida this week to measure ocean waves in the path of Hurricane Ian. The test is one part of a broad effort to improve forecasts for these fast-moving and deadly systems.
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 鈥渉idden鈥� deaths that may have listed something else, like illness or a chronic disease, as the primary cause.
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.
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.
Volunteers spent thousands of hours recording trash on beaches in Washington and Oregon to show that certain beaches, and certain areas of a single beach, are 鈥渟ticky zones鈥� that accumulate litter. Finding patterns for where litter lands could help to better prevent and remove trash in the marine environment.
A 91探花 pilot project is exploring the use of fiber-optic sensing for seismology, glaciology, and even urban monitoring. Funded in part with a $473,000 grant from the M.J. Murdock Charitable Trust, a nonprofit based in Vancouver, Washington, the new 91探花Photonic Sensing Facility will use photons traveling through a fiber-optic cable to detect ground motions as small as 1 nanometer.
For birds that inhabit developed areas of the Pacific Northwest, the reduction in noise and commotion from COVID-19 lockdowns may have allowed them to use a wider range of habitats in cities, a new 91探花 study has found.
As glaciers worldwide retreat due to climate change, managers of national parks need to know what鈥檚 on the horizon to prepare for the future. A new study from the 91探花 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.
Air pollution is not just a problem for lungs. Increasingly, research suggests air pollution can influence childhood behavioral problems and even IQ. A new study led by the 91探花 has added evidence showing that both prenatal and postnatal exposure to air pollution can harm kids. The study, published in Environmental Health Perspectives, found that children whose mothers experienced higher nitrogen dioxide聽(NO2) exposure during pregnancy, particularly in the first and second trimester, were more likely to have behavioral problems….
A new 91探花 study that leverages historical data has found unique support for a 鈥渟afety in numbers鈥� 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.
A team led by the 91探花has produced the first comprehensive report of the impacts of the 2021 heat wave on shellfish.
David Montgomery, a 91探花professor of Earth and space sciences, discusses soil health, food nutrients and human health. He is co-author of “What Your Food Ate,” being published this month.
A new population of polar bears documented on the southeast coast of Greenland use glacier ice to survive despite limited access to sea ice. This small, genetically distinct group of polar bears could be important to the future of the species in a warming world.
The Our Future Duwamish project, available to community groups through The Seattle Public Library, uses an Oculus Quest 2 virtual reality headset to help viewers imagine rising seas from a vantage point along the South Seattle waterway.
To investigate what happens to snow intercepted by trees, 91探花researchers created a citizen science project called Snow Spotter.
Amy Snover, the retiring director of the 91探花Climate Impacts Group, reflects on her past decade of leadership and on how the groundbreaking climate preparedness group has evolved over more than a quarter century of existence.
A new effort at the 91探花 aims to accelerate eDNA research by supporting existing projects and building a network of practitioners to advance the nascent field.
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.
Forest fire smoke can make you sick, and we’re experiencing more them. In terms of public health, it seems logical to reduce forest fires to limit unhealthy air pollution, but forest managers are increasingly seeing prescribed burning as an essential tool to reduce explosive wildfires. How should we plan to deal with the impacts of these fires?
If emissions from greenhouse gases continue, species losses from warming and oxygen depletion of ocean waters could eclipse all other human stressors on marine species by around 2100. Tropical waters would experience the greatest loss of biodiversity, while polar species are at the highest聽risk of extinction
Two 91探花 professors have been honored by the Ecological Society of America for their knowledge and contributions to the field of ecology.
Including the splintering of ice inside clouds around Antarctica improves high-resolution global models’ ability to simulate clouds over the Southern Ocean 鈥� and thus the models鈥� ability to simulate Earth鈥檚 climate.
A new documentary from 91探花 professors Lynn M. Thomas and Daniel Hoffman tells the story of a man accused of starting a wildfire while illegally removing trees from the Olympic National Forest.
Bottle tops, face masks and dog hair 鈥� these are all items usually destined for the dumpster. But 91探花Recycling came up with a unique art contest that takes waste from garbage to gallery.
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.
In the past 20 years, the Arctic has lost about one-third of its winter sea ice volume, and winter sea ice in the Arctic has lost about a foot and a half of thickness over just the past three years. This thinning is largely due to loss of older, multiyear sea ice that is more resistant to melting.
91探花-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 鈥� especially if predictions are correct and climate change will favor fast-growing jellyfish.
Two 91探花 experts in climate change and health are lead authors of the latest report from the Intergovernmental Panel on Climate Change (IPCC). The new report titled Climate Change 2022: Impacts, Adaptations and Vulnerability, published Monday morning, details in over three thousand pages a 鈥渄ire warning鈥� about the consequences of inaction on reducing the emissions that are causing our planet to warm and on implementing interventions to prepare for and effectively manage the dangerous impacts of climate change…
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.
As the green crab invasion in the state worsens, a new analysis method developed by 91探花 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鈥� range is expanding.
Across the globe, endangered species are at risk for illegal poaching. African elephants are sought out for their ivory, rhinoceros for their singular horns, and armadillo-like pangolins for their protective, brittle scales. Add to that list valuable and environmentally sensitive trees illegally harvested throughout the world where entire ecosystems are being deforested and illegal, unreported and unregulated fishing that is devastating oceans. These illicit markets, estimated at $1 trillion annually, cause enormous environmental impacts and have the potential to unleash new, deadly pathogens.
Farmers struggling to adapt to rising temperatures in tropical regions can unleash the benefits of natural cooling, alongside a host of other wins, simply by dotting more trees across their pasturelands. For the first time, a study led by the 91探花 puts tangible numbers to the cooling effects of this practice.
Though usually though of as a solid, glaciers are also slightly compressible, or squishy. This compression over the huge expanse of an ice sheet 鈥� like Antarctica or Greenland 鈥� makes the overall ice sheet more dense and lowers the surface by tens of feet compared to what would otherwise be expected.
With a low supply of and high competition for key nutrients, scientists have puzzled over the vast diversity of microbial species found in the open ocean. A new study shows that time of day is key, with species of marine microbes specializing in different shifts throughout the day and night.
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 91探花 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.
Many nations are calling for protection of 30% of the world鈥檚 oceans by 2030 from some or all types of exploitation, including fishing. Building off this proposal, a new analysis led by the 91探花 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 鈥� changing the pattern of closures as accidental catch hotspots shift 鈥� is much more effective.
