Rising Temperatures Release Methane Locked in the Seabed
New research shows that when ice in the seafloor melts, single-cell organisms metabolize the methane released, preventing the greenhouse gas from reaching the atmosphere.

Sea Level Rise Due to Warming, Weakening of Greenland Glaciers
Increasing ice temperatures and decreasing ice viscosities could lead to "thermal-viscous collapse" of the Greenland ice sheet, raising sea levels as much as 51 centimeters over the next 500 years.
