The Antarctic cycle changes dramatically every year. Why is this important to all of us?
Antarctic sea ice extent has beaten last year's record low. What's more, the melt season is still likely to have a couple of extra weeks to run its course, according to aThey claim that since we started measuring ice in the Antarctic in the late 1970s, there has never been less of it encircling the continent.Melting sea ice has no direct impact on sea levels because the ice is already in ocean water.
They demonstrate that this week, the Antarctic's sea ice fell to 1.91 million square kilometers . This set a new record low, dropping below the previous record of 1.92 million square kilometers set on February 25, 2022. Additionally, frozen seawater is essential due to its role in the great ocean conveyer- the mass movement of water that helps regulate energy in the climate system.
Not to mention sea-ice's significance for life at the poles, including its role as a platform for food sources to cling onto and where some animals can rest.Graph showing Antarctic annual sea ice minimum extent.But is this new record unusual? Or, more significantly, is it something to worry about? In short, it's not clear. From what we know, the Antarctic cycle undergoes considerable annual changes in its summers of thawing and its winters of freezing.
