In 2015, NOAA's Climate Program Office (CPO) invited grant proposals from sea ice and climate scientists looking to better understand and predict Arctic sea ice behavior, on timescales ranging from days to decades. This is our second story on some of the resulting research.
Ice cover on the Great Lakes has been decreasing since the 1970s, affecting everything from fishing to shipping.
The melt season was up to 30 to 40 days longer than average in western, northwestern, and northeastern Greenland, but was close to or below average elsewhere on the ice sheet. Melt area was above average on 52 of the 90 days of the melt season.
Across the globe, changes in salinity over time generally match changes in precipitation: places where rainfall declines become saltier, while places where rainfall increases become fresher. Where did saltiness change over the past decade?
