Solar Forcing Of Modern, Historic Arctic Sea Ice
Only Slightly Less Sea Ice Now Than Little Ice Age
In a new paper (Stein et al., 2017), scientists find that Arctic sea ice retreat and advance is modulated by variations in solar activity.
In addition, the sea ice cover during the last century has only slightly retreated from the extent reached during coldest centuries of the Little Ice Age (1600s to 1800s AD), which had the highest sea ice cover of the last 10,000 years and flirted with excursions into year-round sea ice.
The Medieval Warm Period sea ice record (~900 to 1200 AD) had the lowest coverage since the Roman era ~2,000 years ago.
Powerful deep Arctic Ocean geological heat flow forces are melting the ice, says geologist James Edward Kamis.In an article entitled “Heat From Deep Ocean Fault Punches Hole in Arctic Ice Sheet,” Kamis punches his own holes in the “humans-are-melting-the-ice”chorus.
“A very interesting high temperature and low salinity hole has just been punched in the sea ice … directly above the deep ocean Gakkel Ridge Rift / Fault System,” wrote Kamis in early November. (The event Kamis is referring to took place on October 12, 2015.)
Massive amounts of heat pulsing from the earth
The Gakkel ridge is a gigantic chain of underwater volcanoes snaking 1,800 kilometers (1,100 miles) beneath the Arctic Ocean from the northern tip of Greenland to Siberia. Continue reading »
– Arctic ice pack grew by 41 percent in 2013 (Ice Age Now, July 23, 2015):
Al Gore said it would be clear water by now … Video
The Arctic ice pack has expanded dramatically despite years of doom-laden predictions that it was melting away for good.
British scientists discovered that it grew by more than 40 percent in 2013 thanks to cooler than expected temperatures, and say they were shocked at the speed of recovery in such a short time.
Three years ago Professor Peter Wadhams of Cambridge University forecast that the Arctic would be ice free by 2015 – or 2016 at the latest. And Al Gore made strong claims that the caps would disappear by 2014.
In 2007, 2008 and 2009, Gore publicly and very hysterically warned that the North Pole would be “ice-free” by around 2013 because of alleged ‘man-made global warming.
– Arctic sea ice at highest extent for the date in last five years (Ice Age Now, July 18, 2015):
Meanwhile, Antarctic sea ice is at the 4th highest ever measured.
The Denmark meteorological institute is showing Arctic sea ice at its highest extent for the date in the last five years, and it falls within the norm, one standard deviation.
– Arctic Sea Ice Extent At Its Highest Level In Over A Decade (Real Science, November 15, 2014):
With Antarctic sea ice at a record high, northern hemisphere snow cover near a record high, and Arctic sea ice at a decadal high, government climate experts say that it is the hottest year ever.

Sea-ice in the Arctic. That ice ain’t melting and the polar bears are thriving.
By Dr. Klaus L.E. Kaiser
The Sunday Times has reached a new height of incoherence with its science editor’s, (Jonathan Leake) column on Arctic ice cap in ‘death spiral.’
Nothing could be further from the truth. The ice cover in the Antarctic has recently reached a new all-(recorded)-time extent and the ice cover in the Arctic appears to be on a similar path. No wonder as the frost-free days in the Arctic, above 80 N have been fewer in the last two summers and the last winter in North America was brutally cold and long. Continue reading »
Second only to the melting of the Arctic ice and those “drowning” polar bears, there is no scare with which the global warmists, led by Al Gore, more like to chill our blood than the fast-vanishing glaciers of the Himalayas, which help to provide water for a sixth of mankind. Continue reading »

Arctic sea ice could break apart completely at the North Pole this year, allowing ships to sail over the normally frozen top of the world.
The potential landmark thaw – the first time in human history the pole would be ice-free – is a stark sign of global warming, according to an article Friday on the web site of the The Independent, a London newspaper.
“Symbolically it is hugely important,” said Mark Serreze of the U.S. National Snow and Ice Data Center in Colorado. “There is supposed to be ice at the North Pole, not open water.”
Last year, the fabled Northwest Passage opened as Arctic ice retreated more than ever before.
There is no land at the North Pole, but as long as anyone has looked, it has remained a giant block of ice year-round. Scientists have been watching Arctic sea ice melt more and more each year. But each summer in recent years, the amount of ice has gotten thinner and thinner. Each winter’s freeze, therefore, results in a thinner pack that, this summer, could melt altogether.
“The issue is that, for the first time that I am aware of, the North Pole is covered with extensive first-year ice,” Serreze is quoted by The Independent. “I’d say it’s even-odds whether the North Pole melts out.”
Russia and other countries, meanwhile, have been arguing over who has rights to the region’s resources, including potential oil reserves.
Several studies in recent years have predicted that the North Pole could be ice-free within a few decades. Alarm has ratcheted up every summer as the ice gets thinner and thinner. In a study released June 10, scientist said the rapid meltoff in the Arctic could threaten permafrost in continental soil elsewhere above the Arctic circle in a warm version of the snowball effect.
Last summer saw a record melt of Arctic sea ice, which shrank to more than 30 percent below its average. Around the peak of the melt, in September, air temperatures over land in the western Arctic from August to October were more than 4 degrees Fahrenheit (2 degrees Celsius) above the 1978-2006 average.
“The rapid loss of sea ice can trigger widespread changes that would be felt across the region,” said Andrew Slater, also of the National Snow and Ice Data Center.

WASHINGTON (Reuters) – The thickest, oldest and toughest sea ice around the North Pole is melting, a bad sign for the future of the Arctic ice cap, NASA satellite data showed on Tuesday.
“Thickness is an indicator of long-term health of sea ice, and that’s not looking good at the moment,” Walt Meier of the National Snow and Ice Data Center told reporters in a telephone briefing.
This adds to the litany of disturbing news about Arctic sea ice, which has been retreating over the last three decades, especially last year, when it ebbed to its lowest level. Continue reading »
