Researchers from Arizona State University, led by Professor Steven Desch, have come up with a plan to stop global warming using 10 million wind turbines placed in the Arctic.
The project would involve pumping water using wind turbines onto the surface of the existing ice, in order to thicken it during the winter season.
The only problem? The $500 billion price tag of installing 10 million wind turbines. It would have to be a joint global effort with the support of many countries in order to round up that amount of money.
Professor Desch told Digital Trends:
“Any climate change strategy must include methods of slowing the loss of Arctic sea ice, so that ice reflects sunlight in summer, instead of the dark ocean absorbing it.”
“This article makes the case for that, then explores one idea for increasing Arctic sea ice, which is to use wind power to bring seawater from below the ice sheet to the top of the ice, where it will freeze faster. We calculate the rates of freezing and make some estimates of the effectiveness and cost.”
“The likelihood of this happening depends on whether enough people judge it to be a good idea. We’ve shown it’s not physically impossible or logistically completely infeasible to restore ice in the Arctic, but that’s a far cry from understanding the full impact of the technique or the total breakdown of costs. Given how many people it affects, there would have to be agreement between multiple stakeholders in the Arctic — and even then the costs must be justified by weighing them against other options. But right now the default option is doing nothing, and that comes with its own price tag as climate change is accelerating.”
So what do you think? Is this project worth investing in, or are there easier, less expensive ways to reduce global warming and prevent the sea ice from melting?
