Greenland’s melt season ended a month ago, and since last September the ice sheet has grown at close to record rate.

The animated image shown after the jump shows ice extents for day 233 from 2007 to 2017. Particularly interesting is the variation in the CAA (Canadian Arctic Archipelago), crucial for the Northwest Passage

Last year, experts announced that the Arctic would be ice-free in 2017.

Winter has arrived about 10 days early in the Arctic, and Greenland’s surface has gained 500 billion tons of ice – about 33% above normal.

Satellite observations indicate that the average Arctic sea ice extent has generally decreased since the start of the satellite records in October 1978. Is this period long enough to assess whether the current sea level trend is unusual, and to what extent the decline is caused by humans?
This change in Arctic climate is often promoted as evidence that humans are causing drastic climate change. For instance, an April 29th 2017 article in the Economist (“Skating on thin ice”, pg 16) implied that the Arctic is melting unusually, dramatically and worryingly (…)

In recent months, two new papers published in The Cryosphere have provided a condensed summary of the ice-melt and sea-level-rise consequences of global warming for the Arctic region.
1. Between 1900 and 2010, the Greenland Ice Sheet (GIS) has melted so extensively and so rapidly that the GIS ice-melt contribution to global sea level rise has amounted to 1.5 centimeters for the entire 110-year period. One-and-a-half centimeters. That’s 0.59 of an inch!
2. It gets worse. Between 1993 and 2010, the contribution to global sea level rise has been a disturbing 0.39 of a centimeter. Almost 4/10ths of a centimeter. That’s 0.15 of an inch!

The Greenland Ice Sheet is gaining near record amounts of ice this year. Very little melting has occurred this summer, which is about to start winding down. Temperatures on the Greenland Ice Sheet have been extremely cold, and broke the all-time record for Northern Hemisphere July cold on July 4, at -33C.

The graphic shows the mean September sea ice extent on the northern hemisphere. The plotted values correspond approximately to the sea ice area that ‘survived’ the summer melt in the respective years
The graph illustrates a decreasing trend in sea ice extent since 1978, with annual variations of occationally more than 1 million square kilometres. The 2012 sea ice minimum extented set a new minimum record.

When considering the scale of temperature changes that alarmists anticipate because of Man-made Global Warming and their view of the disastrous effects of additional Man-made Carbon Dioxide emissions in this century, it is useful to look at climate change from a longer term, century by century and even on a millennial perspective.

Globally emitted contaminants accumulate in the Arctic and are stored in the frozen environments of the cryosphere. The microbial potential to degrade anthropogenic contaminants, such as toxic and persistent polychlorinated biphenyls, was found to be spatially variable and not limited to regions close to human activities.

We show that variations in ocean temperature in the high latitude North Atlantic and Nordic Seas are reflected in the climate of northwestern Europe and in winter Arctic sea ice extent. Statistical regression models show that a significant part of northern climate variability thus can be skillfully predicted up to a decade in advance based on the state of the ocean. Particularly, we predict that Norwegian air temperature will decrease over the coming years, although staying above the long-term (1981–2010) average. Winter Arctic sea ice extent will remain low but with a general increase towards 2020.

Norway on Wednesday proposed to open up a record number of blocks in the Barents Sea to oil exploration despite protests from environmentalists and others fearing possible damage to the Arctic region.
The Norwegian oil and energy ministry offered oil companies 93 blocks in the Barents Sea and nine others in the Norwegian Sea, all located beyond the Arctic Circle.
