‘Even so, Coast Guard commanders and allies in Congress say the U.S. will need more icebreakers as climate change reshapes the polar regions. Enough ice has melted to open Arctic shipping lanes — at least seasonally — as well as areas that hold rare-earth metals and perhaps a quarter of the earth’s undiscovered oil and gas.’
So, according to this paragraph, you need more ice breakers because global warming has melted ice creating Arctic shipping lanes. Got it.
Lol! Good catch.
