New, unexpected consequences of climate change keep presenting themselves. A new study from Uppsala University and SLU shows that a decreased snow cover on frozen lakes in boreal forests may inhibit the activity of methane degrading bacteria beneath the ice, thereby causing an increased net production of methane, a powerful greenhouse greenhouse gas.
Melting Arctic glaciers are triggering the release of methane
