University at Buffalo researchers have used plowmarks left by ancient drifting icebergs to reveal evidence of an Ice Age wind system that likely pushed lake-effect snow in the opposite direction.
When rain falls on snow in the Arctic, ice layers can form on top of and within the snowpack. This increasingly common dynamic can influence the ability of animals, including caribou and muskoxen, to forage and move across the landscape. That, in turn, affects the people who rely on wildlife for subsistence, culture, wellbeing and income. Given the widespread impacts of rain-on-snow events, Colorado State University researchers are studying and modeling their effects in Arctic systems. The work is especially important considering the rapid rate of climate change across the region
