Nonuts of the North on polar bears.
If the polar bears need more floating ice to survive, let’s get them some more floating ice! Like artificial reefs, we can build fake floating ice, or make real floating ice, and distribute it across the polar bear habitat. Mightn’t this be expensive? you ask. I dunno maybe. I haven’t priced artificial polar bear ice platforms lately. But I will bet you dollars to doughnuts it would cost a mere fraction of a fraction of a fraction of a fraction of the cost of a Kyoto regime and it would save vastly more polar bears than Kyoto would — at least in, say, the first couple centuries.
