Scientists stunned to discover fossil plants beneath mile-deep Greenland ice, indicating an ice-free landscape in a warmer climate

March 15, 2021 — 
The discovery helps confirm a new and troubling understanding that the Greenland ice has melted off entirely during recent warm periods in Earth’s history—periods like the one we are now contributing to with human-caused climate change.

Meet Dr. Juliana Marini Marson, Assistant Professor in the Department of Environment and Geography

March 8, 2021 — 
Dr. Juliana Marson is a new faculty member at the University of Manitoba whose research focus lies on the polar oceans, their interactions with the cryosphere and climate.

Thaw slumps are also a sign of the permafrost warming. These can be seen just barely in the satellite image as small dark regions along cliff faces, both facing the ocean and within the river drainage basins. Erosion and slumping expose ancient organic carbon to the air and the hydrosphere, thus providing an extensive positive feedback to climate warming.

Declining Arctic sea ice drives divergent arctic shrub growth

December 15, 2020 — 
Arctic sea ice has been in steep decline over the last two decades. Meanwhile, tundra shrub abundance has been increasing in many regions of the Arctic.

Synthesis study demonstrates phytoplankton can bloom below Arctic sea ice

November 19, 2020 — 
Until roughly a decade ago, most scientists assumed that phytoplankton remained in a sort of stasis throughout the winter and spring until sea ice break-up. Now there is a growing body of evidence that suggests under-ice blooms (UIBs) of phytoplankton can occur in low-light environments below sea ice.

Arctic Research Foundation partners with UM and RRC to revolutionize public access to big Arctic data

October 5, 2020 — 
A new partnership between the University of Manitoba (UM), Red River College (RRC), and the Arctic Research Foundation (ARF) is setting out to unlock the big data secrets previously hidden in Canada’s Arctic.

North pole soon to be ice free in summer

April 22, 2020 — 
Using these models, the researchers considered the future evolution of Arctic sea-ice cover in a scenario with high future CO2 emissions and little climate protection. As expected, Arctic sea ice disappeared quickly in summer in these simulations.

How video games help teach Arctic climate science

March 12, 2020 — 
More than 150 middle-and-high school learners met with climate researchers on March 5 for Arctic Science Day. Students learned how new knowledge is developed from working in harsh Arctic conditions, and how the learning process can be a lot like playing video games.
