You’re right, of course. Mitigate was a poor choice of words, but substituting adapt for mitigate doesn’t quite work either. So let me rephrase: While it’s inevitable that we must adapt to a warmer Earth (we already are), it doesn’t follow that we must adapt to some of the negative consequences associated with a warming planet. There are steps we can take to lessen, or mitigate, those consequences.
Take water, for example. A warmer U.S. will certainly exacerbate current and expected future water shortages. But if a certain temperature rise is already baked in (I believe it is), then we will have to adapt to the new normal, but we don’t necessarily have to adapt to the logical and expected drought-like consequences. Maybe there’s a way to mitigate those consequences.
To state the obvious, the U.S. needs to find additional water sources in the coming years. And that’s true even if the temperature stabilizes at the current rate. If temperatures rise by 1.5, 2, or even 3 degrees, then obviously our water situation—especially in the west and southwest—goes from bad to worse to critical.
This is where Canada comes in. They have more than 20% of the world’s fresh water and 7% of the planet’s renewable water supply - all to satisfy the needs of just 0.5 per cent of the world's population. In other words, they have vast amounts of surplus water that can be routed south to the U.S.
This is not a novel idea; it’s been considered before. Naturally, most Canadians are against it, but public opinion and government cooperation can be influenced by money. And rest assured, it would cost a lot of money: tens of billions for the water and an enormous amount of money to get it where it is needed.
So what does this have to do with lowering emissions? Nothing at all. But it does have to do with mitigating some of the consequences of an inevitable warming. And if there is a finite amount of money to spend on environmental issues (and there is), then assuring critical regions of our nation of an adequate water supply should take priority over measures that have little chance of success (reread Kerry’s quote).
