Arc­tic on thin ice

Down to Earth - - THE FORTNIGHT -

THE ICE cover in the Arc­tic sea shrank to its sum­mer min­i­mum in Septem­ber, ac­cord­ing to NASA-sup­ported Na­tional Snow and Ice Data Cen­ter at the Univer­sity of Colorado, Boulder. "Arc­tic sea ice cov­er­age in 2014 is the sixth-low­est recorded since 1978," says Wal­ter Meier, a re­searcher at NASA. Septem­ber is the month when Arc­tic ice reaches its low­est "ex­tent" of the year. Sea ice is frozen ocean wa­ter that melts each sum­mer and re­freezes each win­ter. It acts as an air con­di­tioner for the planet, re­flect­ing Sun's en­ergy. "Even with a rel­a­tively cool year, the ice is so much thin­ner than it used to be," Meier said. "It's more sus­cep­ti­ble to melt­ing."

"By chang­ing our life­style and cre­at­ing con­scious­ness, it (yoga) can help us deal with cli­mate change"
