Sea ice reflects sunlight. When sea ice melts, it becomes more open water that can absorb the sunlight. The warmer the water leads to higher temperatures.
– Changes in the Arctic Ocean can affect ecosystems far away land, says Frans-Jan Parmentier , researchers at the Department of Physical Geography and Ecosystem Sciences at Lund University, who led the new study of the relationship between methane emissions and melting sea ice.
The higher sea temperature allows the microorganisms in previously frozen soils in the tundra comes to life and produces methane.
Since 1990, the sea ice in the Arctic reduce by about 14 percent per decade
– The decrease of the Arctic sea ice is one of the most visible consequences of climate change, and has a huge impact on the Arctic climate, says Frans-Jan Parmentier.
The study was recently published in the journal Geophysical Research Letters.
