Legitimate question: will there be a point where we speak about this war in the past tense, as in `The world lost the war against climate change'? How do we determine that turning point?
I agree that wording is important. Talking about climate changes is important. We need an effort, perhaps greater than the war effort in world war 2 to make the changes necessary because whether we do nothing or make needed changes for the better, change is coming. There is no turning point. The Great Turning is a shift from the Industrial Growth Society to a life-sustaining civilization.
