So you're saying the science is "wildly" off its claim? The north polar ice cap isn't already half gone? No. You want to nitpick exact numbers because that will stall any process, and hey, you have nothing to lose.

You're not poor. You're not at risk. It's the water supplies of millions of poor that are vanishing, not yours. It's the possible forced migration of millions that's pending, not yours.

These are not "useless environmental projects". They are changes we will make regardless. But doing them now will save lives.
