Aerosol reductions could account for up to 40 percent of future Arctic sea ice loss

Anticipated declines in human-produced aerosols could have a significant effect on Arctic sea ice cover over the remainder of the 21st century, accounting for up to 40 percent of the decline in sea ice extent that could occur in the region by 2100, shows a new Geophysical Research Letters study.

Formation of coastal sea ice in North Pacific drives ocean circulation and climate

An unprecedented analysis of North Pacific ocean circulation over the past 1.2 million years has found that sea ice formation in coastal regions is a key driver of deep ocean circulation, influencing climate on regional and global scales, finds a new study in Paleoceanography.

On the rocks: The challenges of predicting sea level rise

As the loss of West Antarctica's ice sheet threatens to raise sea level and flood the world's coasts, scientists must improve projections by understanding the physics where glaciers meet the ocean.
