NEW DELHI, INDIA (tecake.in) - According to a recent report, it is estimated that the arctic sea would probably be free of sea ice by the year 2040. The earlier estimate was for the year 2070. Arctic sea ice is melting rapidly. Since the past three decades, the ice sea in the Arctic has fallen by more than half.
A scientist at Arizona State University is bringing up a new scheme for adding more ice to the Arctic. This is to slow down the rising global temperature. This won’t be much expensive.
Explaining Desch’s theory, Perkins wrote, “Ice is a good insulator, says Steven Desch, a planetary scientist at Arizona State University in Tempe. That’s why moons such as Jupiter’s Europa and Saturn’s Enceladus, among others, may be able to maintain liquid oceans beneath their thick icy surfaces. On Earth, sea ice is much thinner, but the physics is the same. Ice grows on the bottom surface of floating floes. As the water freezes, it releases heat that must make its way up through the ice before escaping into the air. The thicker the ice, the more heat gets trapped, which slows down ice formation. That’s bad news for the Arctic, where ice helps keep the planet cool but global warming is causing ice to melt faster than it can be replaced.”
Melting of glaciers in the Arctic has an impact on rising probability of droughts and floods. The warming affects the ocean currents as well as the winds which affect the monsoon across the world. All this has an impact on food production and cropping patterns. This would also affect the coastal cities with the rise in sea level. This has been an issue of concern for Scientists and would now affect larger community. The production of carbon dioxide must be lowered as it warms up the environment.
Ust bIn another 15-20 years the ocean would be free of ice during the summers. The only advantage which could be seen is for the shipping companies which can then find new sea routes easily.
The glacier area is now reduced by a distance of 50 thousand square kilometers approximately. The rate of rising in temperature over the last half-century was twice higher than other regions of the world. If the glaciers disappear then the route from Asia to Europe would pass through the Northern sea route.
This is not the ideal opportunity for nations to make a descending change in accordance with their responsibility regarding bringing up measures that would back off a dangerous atmospheric situation. The cost of not venturing up endeavors is massive. The poor ones will be most exceedingly influenced and could barely manage.
The question is that how could humans make the ice thicker.
The machines which used to suck the water will work in a similar way as the windmills and would cost about $50,000 each which is quite expensive.
“Suck up near-freezing water from under the ice and pump it directly onto the ice’s surface during the long polar winter,” Perkins wrote, citing Desch. “There, the water would freeze more quickly than underneath the ice, where it usually forms.”
