The Cyrosphere & Climate Lab (CryoLab) is the research group of Dr. Luke Trusel in the Department of Geography at Penn State University.
Our research explores the response of Earth's ice sheets in Antarctica and Greenland to past, ongoing, and future climate change.
We integrate observations, ice cores, and climate models to contextualize recent change and elucidate connections between the polar regions and the broader Earth system.
Fundamentally, we seek to understand how climate impacts the ice sheets, and in turn, what these changes mean for us.
Recent news & events
August 2019: I have been quoted in several recent news articles about the exceptional Greenland Ice sheet surface melt this summer:
June 2019: Move to Penn State University. I am pleased to announce that I will be moving to a tenure-track position in the Department of Geography at Penn State University later this summer. Very excited about the opportunities that this will present. Students already at Penn State as well as prospective graduate students are encouraged to reach out about research opportunities! More to come soon…
May 2019: Thrilled to contribute to an important new paper in Nature led by Matt Osman of the MIT-WHOI Joint Program. Here, we use Greenland ice cores and a geochemical proxy to reconstruct marine primary productivity in the North Atlantic Ocean over the last several centuries. Our reconstruction reveals an Industrial-era decline in productivity in this biologically and economically-important region. These declines track the anthropogenic warming and increased runoff from the Greenland ice sheet. Further productivity declines due to continued warming could result in further reductions in productivity, with cascading effects across marine food webs.
