Study connects greenhouse gas emissions to polar bear population declines, enabling greater protections under Endangered Species Act
A new paper from the UW and Polar Bears International quantifies the relationship between greenhouse gas emissions and the survival of polar bear populations. The paper combines past research and new analysis to provide a quantitative link between greenhouse gas emissions and polar bear survival rates.

For 17 years, UW program has provided an interdisciplinary nexus for climate research and education
Over 17 years, the program has evolved into a campuswide, interdisciplinary, student-driven program on climate change research, communication and action. A recent publication looks at the program history and current mission.

Orbital variations can trigger ‘snowball’ states in habitable zones around sunlike stars
Aspects of an otherwise Earthlike planet’s tilt and orbital dynamics can severely affect its potential habitability — even triggering abrupt “snowball states” where oceans freeze and surface life is impossible, according to new research from UW astronomers.

Record-low 2016 Antarctic sea ice due to ‘perfect storm’ of tropical, polar conditions
This exceptional, sudden nosedive in Antarctic sea ice last year was due to a unique one-two punch from atmospheric conditions both in the tropical Pacific Ocean and around the South Pole.

Long-term Pacific climate cycle linked to expansion of Antarctic sea ice
A long-term Pacific climate cycle may be driving the expansion of Antarctic winter sea ice since 2000, but a new study finds that the trend may soon reverse.

UW researchers attend sea ice conference — above the Arctic Circle
University of Washington polar scientists are on Alaska’s North Slope this week for the 2016 Barrow Sea Ice Camp. Supported by the National Science Foundation, the event brings together U.S.-based sea ice observers, satellite experts and modelers at various career stages to collect data and discuss issues related to measuring and modeling sea ice. The…

A warmer planetary haven around cool stars, as ice warms rather than cools
In a bit of cosmic irony, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars. This is due to the interaction of a star’s light with ice and snow on the planet’s surface.

Model provides successful seasonal forecast for the fate of Arctic sea ice
Relatively accurate predictions for summer sea ice extent in the Arctic can be made the previous autumn, but forecasting more than five years into the future requires understanding of the impact of climate trends on the ice pack.
