Could a 400bn plan to refreeze the Arctic before the ice melts really work?

https://www.theguardian.com/world/2017/feb/12/plan-to-refreeze-arctic-before-ice-goes-for-good-climate-change

Physicist Steven Desch has come up with a novel solution to the problems that now beset the Arctic. He and a team of colleagues from Arizona State University want to replenish the region’s shrinking sea ice – by building 10 million wind-powered pumps over the Arctic ice cap. In winter, these would be used to pump water to the surface of the ice where it would freeze, thickening the cap.

The pumps could add an extra metre of sea ice to the Arctic’s current layer, Desch argues. The current cap rarely exceeds 2-3 metres in thickness and is being eroded constantly as the planet succumbs to climate change.

“Thicker ice would mean longer-lasting ice. In turn, that would mean the danger of all sea ice disappearing from the Arctic in summer would be reduced significantly,” Desch told the Observer.

Desch and his team have put forward the scheme in a paper that has just been published in Earth’s Future, the journal of the American Geophysical Union, and have worked out a price tag for the project: $500bn (£400bn).


Something tells me that even if they magically found the money for this, it would take decades to build, and by then there won't be much ice left to build upon.

This is not my considered opinion, merely a knee-jerk reaction…



All the projects are highly imaginative – and extremely costly. The fact that they are even being considered reveals just how desperately worried researchers have become about the Arctic. “The situation is causing grave concern,” says Professor Julienne Stroeve, of University College London. “It is now much more dire than even our worst case scenarios originally suggested.’

spending $500 bn on this project that would take decades to build vs utilizing what we know now that we can step up immediately to minimize and maybe even reverse global climate change.

I wonder who would win the bid on building and installing these 10 million wind-powered pumps?
