Scientists Worried by Alarming Delay in Arctic Sea Ice Refreezing

Scientists Worried by Alarming Delay in Arctic Sea Ice Refreezing. The seasonal refreezing of Arctic sea ice has come to an alarming standstill this year. . Despite the fact that it’s already late October, ice has not formed in a key region off the coast of Siberia. . It is the first time in recorded history that the Laptev Sea has yet to freeze this late into the year. . An altered melting and refreezing timeline could have detrimental effects on the world. . Usually, the ice that forms along the Siberian coastline spreads across the Laptev, carrying nutrients across the Arctic. . The ice travels all the way to the Fram Strait, a passage between Greenland and Svalbard, where it finally melts in the Spring. . However, a later freeze increases the likelihood of the ice melting before it reaches its final destination. . As a result, plankton across the Arctic will receive less nutrients, reducing their capacity to remove carbon dioxide from the Earth’s atmosphere. . This in turn contributes to global warming, causing higher temperatures and even less ice formation. 2020 is another year that is consistent with a rapidly changing Arctic. Without a systematic reduction in greenhouse gases, the likelihood of our first ‘ice-free’ summer will continue to increase by the mid-21st century, Zachary Labe, Colorado State University, ‘The Guardian’
