Scientists Propose Arctic Refreezing to Save the Ice

A team of scientists from Arizona proposed Arctic refreezing as a solution against ice melting

A team of scientists from Arizona State University found a simple and potentially efficient idea that might help us save our polar regions and prevent sea level rise. It might be as easy as it sounds – Arctic refreezing.

Their idea implies making new ice caps that can replace the disappearing ones. So far, this sounds like the only idea than can actually be applied to save the Arctic. Unfortunately, the costs involved in building a machine that could make ice caps lie somewhere around $500 billion.

The ice caps in the Arctic are melting at record speed because of greenhouse gas emissions that cause global warming. If we do not reduce the emissions, we might risk losing the entire ice surface from the Arctic before 2030.

People know what are the consequences of fossil fuel use and pollution in general, but it is quite hard to significantly reduce carbon emission so suddenly that it could provide a palpable result. This is when the Arizona scientists came into action.

Steven Desch is a professor of astrophysics at Arizona State University. He, together with a team of scientists, came up with this wacky idea that might bring important result and does not call on people to take action and reduce pollution.

They proposed Arctic refreezing. This implies the freezing of the water under the ice caps and produce more ice. For this, they might need 10 million pumps which are wind-powered. These pumps can extract the water from underneath the ice and spit it over the ice, where it can refreeze.

This sounds simple enough to be put into action. However, the building of the pumps is expensive and complicated. The idea is just a theoretical proposal at the moment, but immediate action must still be taken. At the rate at which the ice melts, many animals are threatened with losing their habitats and their food.

The Arctic has one of the most sensitive climate systems in the world and a huge unbalance in this ecosystem might cause irreversible consequences to other environments too. The Arctic refreezing technique might be costly and complex, but this can actually be a solution against the quick degradation of the ice layers that threaten so many animal populations.
