Some kind of action to reduce greenhouse gas emissions is urgent. We'll say what we've said before. Many scientists believe cycles of the sun have much more to do with these stages than anything humankind has wrought. Indeed, most of the warming in the last century occurred before 1950, before the explosion in automobile use, for example. The National Academy report is useful in adding pieces to the overall picture but hardly the stuff that compels draconian measures like those contemplated by far-left environmentalists.
More study is needed.
Remember, it was just a couple of decades ago that some scientists thought the Earth was cooling, and many of the same members of the current alarmist crowd no doubt thought urgent action was needed then, too.
