Declining Arctic sea ice over the last several years is a reflection of our changing climate. The loss of sea ice reverberates through the earth system affecting Earth’s radiation balance, ocean temperatures and circulation, and marine and terrestrial ecosystems. A new study forecasts a 92% chance of a record low extent of Arctic region sea ice.
CU-BOULDER Research Group Forecasts 92 Percent Chance of Record Low Arctic Sea Ice Extent in 2007
“During the first week in July, the Arctic sea ice started to disappear at rates we had never seen before,” said Drobot, who leads CCAR’s Arctic Regional Ice Forecasting System group in CU-Boulder’s aerospace engineering sciences department.
“We have been seeing a sharp decline in thicker, multi-year ice that has survived more than one melt season,” said CCAR Research Associate James Maslanik. “This has been replaced in many areas by a thin, first-year layer of ice as well as by younger, thinner types of multi-year ice. The thinner ice just does not have the mass to withstand the effects of warming climate.”
