Scientists say critical ice in the Arctic Ocean melted to record low levels this overheated summer.
The National Snow and Ice Data Center reported Monday that the extent of Arctic sea ice shrank to 1.58 million square miles and is likely to melt more in the coming weeks. That breaks the old record of 1.61 million square miles set in 2007. Figures are based on satellite records dating back to 1979.
Data center scientist Ted Scambos says the melt can be blamed mostly on global warming from man-made emissions of greenhouse gases.
Scientists say Arctic sea ice – ocean water that freezes – helps moderate temperatures lower on the globe and is crucial for polar bears. Greenland has also had record melt this year.
- Heli-skiing has long been a controversial topic in Haines. The interests of the industry often clash with people who live near heliports and don’t want the noise disturbing their peace and quiet. But there’s another group that’s impacted by helicopter noise: mountain goats.

- From the Aleutian island of Akutan to the arctic village of Kiana, 13 communities have been crowned champions of a rural energy competition. The U.S. Department of Energy recently announced that it will help these communities cut their energy use by 15 percent by training local utility providers.
- It’s costing 14 percent more to take the ferry to and from the Lower 48. The higher fare is part of another round of tariff increases aimed at boosting income and equalizing rates across all routes.
