ARCTIC - Are winds a driving force for sea ice loss in the Arctic?

In a new Journal of Climate article, MAPP and CVP-funded authors Ian Baxter and Qinghua Ding conduct a set of nudging simulations by specifying observed winds into a fully coupled model to assess the sensitivity of the sea ice response to different wind patterns.

ARC - Arctic Shipping Routes Are Feeling the Heat

Controversy over shipping routes in the Arctic Ocean is intensifying in light of recent climate science projections of sea ice melt. By midcentury, ice-free routes in international waters once covered by summer sea ice may appear for the first time in recent history, according to new research. A more accessible Arctic could influence the timing, sustainability, and legal status of international shipping.
