Could Arctic sea ice decline be slowed by using millions of wind-powered pumps to transport water to the region, where it can freeze and thicken the ice cap? Scientists from Arizona State University seem to think so and have detailed their plan in the journal Earth’s Future. According to physicist Steven Desch and his colleagues, climate change could cause the Arctic to be ice-free during the late summer months within the next two decades, and it is unlikely that temperatures and greenhouse gasses could be decreased in time to prevent such an occurrence.

seeder Posted February 16, 2017 #4 Share Posted February 16, 2017 (edited) OK...this is a huge stretch of the imagination Quote Scientists propose refreezing Arctic in battle against climate change Project would involve 10 million devices and cost $500 billion US A group of researchers has proposed using wind-powered pumps to refreeze the Arctic. The proposal seems ambitious: it involves 10 million devices deployed over 10 per cent of the Arctic, at a cost of $500 billion US. Lead author of the paper, astrophysicist Steven Desch, concerned about what some climatologists predict to be an ice-free Arctic by 2030, challenged a group of his students at Arizona State University to develop a method to refreeze the Arctic. http://www.cbc.ca/news/technology/scientists-refreeze-arctic-1.3980429 http://www.mirror.co.uk/science/scientists-reveal-400-billion-plan-9831177 Edited February 16, 2017 by seeder 1 Link to comment Share on other sites More sharing options...

Read more: redOrbit and Earth's Future It might work, but as long as we keep pumping CO2 into the air, we will have to keep building more turbines. Global warming isn't going to raise the temps a few degrees, then disappear. As long as we continue polluting, it will keep getting warmer. Wind turbines in the Arctic might slow things down, but they won't stop it. Better idea: convert to wind power with turbines located closer to power markets. That will reduce pollution and the need for exotic geoengineering projects. Doug 1 Link to comment Share on other sites More sharing options...
