Melting Arctic sea ice accelerates methane emissions

Published: 17/09/2015
[font size=4]Methane emissions from Arctic tundra increase when sea ice melts, according to a new study from Lund University in Sweden. This connection has been suspected before, but has lacked strong evidence until now.[/font]
[font size=3]“Changes in the Arctic Ocean can affect ecosystems located far away on land, ” says Dr. Frans-Jan Parmentier, the study’s lead author and researcher at the Department of Physical Geography and Ecosystem Science, Lund University.
Bright sea ice reflects most sunlight, while open water absorbs most sunlight. Less sea ice, therefore, leads to more absorbed heat, and higher temperatures throughout the North Pole region. This stimulates the production of methane by microorganisms in permafrost soils, which also drives the change towards a warmer climate.
“While numerous studies have shown the effects of sea ice loss on the ocean, there are only a few that show how this oceanic change affects ecosystems on the surrounding land. Our research shows that to understand the impact of climate change on the Arctic, the ocean and land cannot be viewed separately“, Frans-Jan Parmentier explains.
