Current estimates suggest that, for the Arctic as a whole, nearly half of the observed loss of summer sea ice cover is not due to anthropogenic forcing, but due to internal variability.” Ding et al., 2019 Every summer, the Arctic ice cap melts to what scientists call its "minimum" before colder weather begins to cause ice cover to increase. In this photo taken on Thursday, June 13, 2019 sled dogs make their way in northwest Greenland with their paws in melted ice water. Antarctic sea ice has greater year-to-year variability than the Arctic, and little evidence of long-term change. The polar vortex is keeping cold air locked up over the North Pole. The sea ice cover is one of the key components of the polar climate system. This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 through 2020, with a graph overlay. By Paul Homewood . Marc Morano featured a post about a fascinating Chinese study from Dr. Patrick Michaels at the website of CFACT’s friend and ally the Competitive Enterprise Institute.. The total amount of ice is still below average. In 2020, the Arctic minimum sea ice covered an area … However, a new study from earlier this year finds this is not the case, as Pat Michaels explains: The West Antarctic Ice Sheet is growing, but I bet you didn’t … “That’s how the warming of the ocean translates,” Khazendar says. It has been a focus of attention in recent years, largely because of a strong decrease in the Arctic sea ice cover and modeling results that indicate that global warming could be amplified in the Arctic on account of ice-albedo feedback. The forthcoming … At a Glance. June 6, 2019 by Robert Arctic sea-ice volume was higher on June 1st than on the same date in 2011 and far, far higher than on the same date in 2012, 2016 and 2017. The 2018 and 2019 winter surely had plenty of very cold Arctic air over Central and Eastern Canada with Labrador experiencing an extremely cold spring in 2018 - and thus a rapid rebuilding of the Greenland ice sheet during the winters of 2016 into 2019. But sea ice returned to normal levels once the El Niño ended in 2016. Arctic sea ice volume growing, not shrinking! Most recently, Arctic sea ice thickness for 2019 has shown no major deviation from the 9-year average (2004–2013) and has mostly displayed a close correlation … The West Antarctic ice sheet, the biggest mass of ice in the world, has been growing since the end of the nineteenth century. “Temperatures in the Arctic are rapidly falling (from -23 deg to -28 deg C) and the ice has been expanding all this year (2019), says John of Cloverdale, Western Australia. While there is evidence that the ice cap in East Antarctica is growing, it has been widely claimed that it has been melting back in the West.. “No rising temperatures in the Arctic according the latest DMI plot.” Arctic sea ice volume is now higher than on this date in the past three … So, while the glacier is growing, the ice sheet is still losing tremendous mass and contributing to sea-level rise. Arctic sea ice volume has been on a steady decline during the last three centuries. The most recent minimum (February 2020) and maximum (September 2019) sea ice extents in the Antarctic were below average, but not record lows. More of the Arctic is covered by ice than at any time since 2010.
