A popular scare story running in the media is that the Greenland ice sheet is about to slip its moorings under ferocious and unprecedented Arctic heat and arrive in the reader’s front room any day now (I exaggerate, but not much). Meanwhile back in the scientific world, scientists are scrambling to understand what natural causes lie behind the sudden slow-down in Greenland’s summer warming and ice loss dating back to 2010. The recovery of Arctic summer sea ice has been spectacular of late, with the U.S.-based National Snow and Ice Data Center reporting that this year’s September minimum was 1.28 million square kilometres higher than the 2012 low point of 3.39 million square kilometres.
Three Japanese climatologists have recently published a paper noting that “frequent occurrence of central Pacific El Niño events has played a key role in the [abrupt] slow-down of Greenland warming and possibly Arctic sea ice loss”. Of course such findings play havoc with the simplistic ‘settled’ science notion that carbon dioxide produced by humans burning fossil fuel is the main, if not only, driver of global temperature warming or cooling – a notion that leads many green activists to claim that the climate will stop changing if society signs on to a ‘Net Zero’ CO2 emissions agenda.link
