Nonlinear Dynamics May Lead to Faster Retreat of Antarctic Ice
The Antarctic ice sheet behaves like a non-Newtonian fluid and may be more nonlinear than previously thought. This impacts its future stability and requires revisions to predictions of sea level rise.

Arctic Sea Ice After CO2 Recovery: Implications for North Atlantic Weather
Incomplete Arctic sea ice recovery results in equatorward-shifted winter jets. The North Atlantic jet shift is particularly uncertain due to the ocean circulation acting as an additional driver.
