Whoa, break out the lawn chairs. That’s July weather back home in Maine.
Reports of an ancient, hot Arctic—presumably because of greenhouse gases—are sure to foster theories about global warming. Public sentiment about global warming doesn’t make it fact. Global warming is a theory, and it’s one I skeptically view.
