Human-wildlife conflicts rising worldwide with climate change
Research led by scientists at the University of Washington’s Center for Ecosystem Sentinels reveals that a warming world is increasing human-wildlife conflicts globally. They show that climate shifts can drive conflicts by altering animal habitats, the timing of events, wildlife behaviors and resource availability. It also showed that people are changing their behaviors and locations in response to climate change in ways that increase conflicts.

Climate ‘presses’ and ‘pulses’ impact Magellanic penguins — a marine predator — with guidance for conservationists
Climate change will reshape ecosystems through two types of events: short-term, extreme events — or “pulses” — and long-term changes, or “presses.” Understanding the effects of presses and pulses is essential as conservationists and policymakers try to preserve ecosystems and safeguard biodiversity. Researchers at the University of Washington have discovered how different presses and pulses impacted Magellanic penguins — a migratory marine predator — over nearly four decades and found that, though individual presses and pulses impacted penguins in a variety of ways, both were equally important for the future survival of the penguin population. They also found that these types of climate changes, taken together, are leading to an overall population decline at their historically largest breeding site.

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.

Top predators could ‘trap’ themselves trying to adapt to climate change, study shows
A study led by University of Washington researchers shows that over a 30-year period, African wild dogs shifted their average birthing dates later by 22 days, an adaptation that allowed them to match the birth of new litters with the coolest temperatures in early winter. But as a result of this significant shift, fewer pups survived their most vulnerable period because temperatures during their critical post-birth “denning period” increased over the same time period, threatening the population of this already endangered species. It is the first study to show that large mammalian carnivores are making major changes to their life history in response to a changing climate.

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.

Newest satellite data shows remarkable decline in Arctic sea ice over just three years
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.

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.

Researchers find concerns for animals tied to same habitats
Like humans, wild animals often return to the same places to eat, walk on the same paths to travel and use the same places to raise their young. A team led by researchers at the University of Washington and the University of Wyoming has reviewed the scientific literature and found that, while “consistent” behavior may be beneficial when environmental conditions don’t change very fast, those benefits may not be realized in the ever-changing world dominated by humans.

Drier, warmer night air is making some Western wildfires more active at night
Firefighters have reported that Western wildfires are starting earlier in the morning and dying down later at night, hampering their ability to recover and regroup before the next day’s flareup. A study by University of Washington and U.S. Forest Service scientists shows why: The drying power of nighttime air over much of the Western U.S. has increased dramatically in the past 40 years.

Climate change to fuel increase in human-wildlife conflict, UW biologist says
Climate change is further exacerbating human-wildlife conflicts by straining ecosystems and altering behaviors, both of which can deepen the contacts — and potential competition — between people and animals. In an article published July 30 in the journal Science, Briana Abrahms, an assistant professor of biology at the University of Washington and its Center for Ecosystem Sentinels, calls for expanding research into the many ways that climate change will impact the complex interplay between human activities and wildlife populations.

Limiting warming to 2 C requires emissions reductions 80% above Paris Agreement targets
Even if all countries meet their Paris Agreement goals for reducing emissions, Earth has only a 5% chance of staying below 2 C warming this century, a previous study showed. But reductions about 80% more ambitious, or an average of 1.8% drop in emissions per year rather than 1% per year, would be enough to meet the Paris Agreement’s temperature goal.
