Pump meltwater back on Antarctica? Do you have 850,000 wind turbines?
With sea levels rising and Antarctica's temperatures well below freezing, some people have raised the question: What would happen if we took water out of the oceans and pumped it onto the icy continent to freeze?
A group of scientists put that question to the test in a new study that explores the physical possibility and economic feasibility of geoengineering climate solutions in the future.
The results offer a warning about the costs that today's greenhouse gas emissions may be creating for future generations.
The Antarctic ice sheet is constantly flowing toward the ocean, so the scientists used an ice dynamics simulation to calculate how far inland the water would have to be sent to prevent it from re-entering the ocean for 1,000 years. The result: about 700 kilometers, and it would have to be on East Antarcticathe West Antarctic Ice Sheet would be too unstable.
