Why can't we be friends?
Before we congratulate ourselves too much, we should keep in mind the evidence, although compelling, is still circumstantial. If for any reason it proves either exaggerated or incorrect, or the effects totally different from what we expect (like an ice-age, instead of an ice-melt) it will only discredit the responsible idea that we should monitor our industrial activities and follow common sense when it comes to environmental controls on industry.
Nobody likes an I-told-you-so attitude, and the boy who cried wolf eventually did meet one. Let's resist the temptation to bludgeon our opponents with this, sooner or later the shoe will be on the other foot.
And let's hope they recognize this and seek out future common ground, instead of revenge.
