Researchers discover evidence of melting ice sheet in Greenland

July 21, 2023 — 
Researchers from the University of Manitoba and fifteen other institutions have made a breakthrough discovery in understanding climate change and its implications, revealing that at least 20% of Greenland was green 416,000 years ago, a new study in the journal Science shows.

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.

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.
