A massive polar ice cap seems to be melting. What are we going to do to stop it?
The answer, as I've often posited in this space, is "likely nothing." Oh, I don't mean literally "nothing"; I'm sure people will continue to write angry editorials and buy "green" consumer products. But I don't think we're likely to do much in the way of actually reducing greenhouse-gas emissions, which contribute to the climate change that is melting the ice caps.
