Arctic change reverberates around globe, experts say

Most of the sea ice that forms each fall and winter in the Arctic now melts each spring and summer, a recent change that is impacting global patterns of weather and trade as well as the U.S. military’s strategic planning, experts told reporters during a briefing Tuesday.

“There are tremendous two-way and multiple interactions between the Arctic and the rest of the world,” retired Rear Adm. David Titley said during the teleconference organized by Climate Nexus, a group trying to raise awareness about climate change.
