Taken by a member of the ICESCAPE mission on board the U.S. Coast Guard Cutter Healy as it steamed its way south in the Arctic Ocean towards the edge of the sea ice on July 20.
in 2007, the largest fire ever recorded in the Arctic swept across the Alaskan Northern Slope region, releasing an estimated 2.1 teragrams (2.3 million tons) of carbon into the atmosphere. Researchers estimate that the release of carbon was equivalent to a year’s worth of carbon storage for the entire Arctic tundra biome. Climate warming in the Arctic may lead to a greater frequency of such large fires, putting permafrost at risk of thawing and releasing more CO2.
“The loss of apex consumers is arguably humankind’s most pervasive influence on the natural world,” argue the authors of a new report published in the journal Science, which looked at the decline of large predators and other ‘apex consumers’ at the top of the food chain.
Researchers on the NASA-funded ICESCAPE mission—Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment—have been examining melt ponds and the ice around them as seen in the image below.
Researchers who have been manipulating a northern Wisconsin lake have been able to detect a warning signal for the impending collapse of an ecosystem.
If many of these plankton blooms are trending earlier each year, then the seasonal return/growth of the fish population in these areas is gradually becoming “out of sync” with the primary producers in this region. This may mean insufficient food supply to maintain robust fish populations.
