The steady increase in global temperatures is particularly disastrous for your polar ice caps. Experts warn that when this trend continues, there won’t be any late summer ice in the Arctic region because of the 2030’s. The very best solution, however, should be to reduce our greenhouse gas emissions now. Speculate which is not happening, scientists are frantically trying to think of alternative tips on how to try to reverse the situation.
The latest idea comes from a team of researchers led by Arizona State University’s Steven Desch. Inside the proposal outlined from the journal Earth’s Future in December 2016, the group suggests using large pumps to attract water from beneath the ice and spray it appears to. Since this is the coldest part, it is going to force the water to freeze rapidly. The pumps, kept afloat with buoys, are going to be operated by the high Arctic winds, harnessed by windmills. To enhance the impact, accomplishing this would transpire during wintertime. The scientists believe their idea should help improve the overall thickness in the ice sheet within days, rather than months and years it requires to refreeze naturally.
The researchers estimate that millions of pumps could be expected to raise the thickness in the ice sheet by about 1-meter in a winter. Given that sea ice normally grows merely by several meters every winter, the excess meter could make a substantial difference. “Thicker ice means longer-lasting ice,” says Desch, “In turn, that would mean the danger of all sea ice disappearing with the Arctic in summer could well be reduced significantly.”
Though the theory is perhaps intriguing, it is not easy to implement. Desch brilliant team estimate the refreezing would cost as a minimum $50 billion USD annually. Mainly because it would take regarding a decade in order to the Arctic ice shelf entirely, the total cost would figure to over $500 billion USD! The way in which researchers could somehow purchase the funding, many experts are skeptical concerning the idea, which, to this point, is solely theoretical.
Julienne Stroeve, a senior scientist in the National Ice and snow Data Center, is one of the skeptics. The expert states that around the world brought on by the increasing skin tightening and levels cannot be stopped, the way in which ice refreezing works as planned. Also, since Arctic would carry on and have the excess heat within the lower latitudes through atmospheric and ocean circulation, it will mitigate any refreezing efforts. Desch agrees and admits that his idea may be a band-aid, not the answer. However, the astrophysicist argues the Arctic ice shelf is crucial for the future well-being and now we should do everything we’re able to in order to it.
The ice it isn’t just required for the area’s marine life and also to assist combat global warming, because it reflects sunlight. Water, on the other hand, absorbs it, causing temperatures to further. Additionally, once the ice thaws, it releases the methane trapped inside further triggering the greenhouse effect.
Furthermore, the ice helps regulate temperatures on the globe. Jet streams – the prime winds that originate from the temperature distinction between the polar and tropical air masses – help move weather systems throughout the world. When sea ice decreases, the jet streams weaken, altering global weather patterns. Many researchers suspect that this anomalous weather witnessed nowadays, including California’s extended drought, Siberia’s ‘Snowmageddon’ winters and the UK’s extreme flooding, have been triggered by the melting of polar ice caps.
This isn’t the first-time scientists have suggested a radical idea to combat the adverse effects of worldwide warming in the Arctic. Previous proposals include artificial whitening within the poles by spraying aerosol particles to mirror sunlight into the atmosphere and creating artificial clouds to cease the daylight from reaching the outer lining altogether. Unfortunately, none of the projects may see sunlight of day because of the astronomical costs associated with each. But Desch and his team usually are not discouraged. They’re currently perfecting creating a prototype to exhibit everyone around you that here is the plan is not as outlandish as it sounds.
