But we do need to put a realistic cost on these things. Physicist Steven Desch and a team of his colleagues at Arizona State University have proposed a novel solution to replenish the melting Arctic ice cap. The scientists' idea involves building 10 million wind-powered pumps over the ice and pumping water over it during the winter months in order to thicken the cap. Desch and his team have estimated that it will cost $500bn to implement the technique. In their study, published today in Nature Communications, they estimate that such an approach would be feasible for about half of the world's land surface by 2050.
