Arctic Ocean to have less ice, more water by 2050s

New York: The entire Arctic coastline and most of the Arctic Ocean will experience an additional two months of open water each year by the 2050s, projects a new study.

Some sites in the Arctic Ocean, once covered by sea ice may see more than 100 additional days of open water, the findings showed.

The researchers used climate simulations to see how the number of open water, or sea-ice-free, days change from 1850 to 2100 in our planet's northernmost ocean. They analysed multiple runs or "realisations" from a single climate model.

For example, at Drew Point, open water is already shifting from pre-industrial conditions. Once present about 50 days a year on average, open water is now present about 100 days a year.

By the 2070s, the modelling study concluded, there could be close to 200 days a year with no sea ice at Drew Point, which is likely to worsen coastal erosion.

According to their analysis, the entire Arctic coastline and most of the Arctic Ocean will experience an additional 60 days of open water each year by the 2050s, and many sites will have more than 100 additional days.
