Tiny particles bubbling up from the tops of melting sea ice into the Arctic sky may be a key, understudied element of cloud formation in that climate-sensitive region. Researchers from Colorado State University have published findings in Geophysical Research Letters that highlight how these airborne “ice-nucleating particles” from biological sources, such as bacteria, provide a platform […]
A new ventilation system component developed by engineers at the University of Alaska Fairbanks and the Cold Climate Housing Research Center is helping indoor air quality in cold climates while saving energy. The Arctic Dual Hood for Heat Recovery Ventilation simplifies installation of heat recovery ventilators, or HRVs, by using a single opening through […]
When permafrost is perma-lost, the global carbon cycle is altered and coastal ecosystem are affected In a first-of-its-kind study, a team of researchers led by geoscientist Michael Rawlins at the University of Massachusetts Amherst has shown in fine-grained detail what happens when Arctic permafrost thaws. Focusing on a Wisconsin-sized area of Alaska’s North Slope containing hundreds […]
Beavers may be new to the Arctic, but they’re already leaving their mark. The industrious rodents are expanding their range as a result of environmental change, pushing their way north into permafrost and tundra landscapes. Their arrival carries many consequences for subsistence users. Creeks that once supported reliable fishing are now beaver-dammed. Fish and […]
