The Greenland ice sheet sits atop the world’s largest island and holds the equivalent of 7.4 m of potential sea level rise. Following a period of relative stability from the 1970s to early 1990s, the ice sheet began losing ice at an accelerating rate and has now experienced annual net ice loss every year since 1998.

Arctic Ocean Primary Productivity: The Response of Marine Algae to Climate Warming and Sea Ice Decline
Autotrophic single-celled algae living in sea ice (ice algae) and water column (phytoplankton) are the main primary producers in the Arctic Ocean.
The Arctic tundra biome occupies Earth’s northernmost landmasses and forms a “wreath” of treeless vegetation that encircles the Arctic Ocean. Arctic tundra ecosystems are strongly influenced by warming air temperatures, and thus have become a focal point of global environmental change.
