Anthropogenic Influence On Arctic Climate
‘Too Small To Be Detected’
The evidence compiled in scientific papers continues to rapidly accumulate.
An anthropogenic signal in the regional Arctic climate is still too small to be detected.
Temperature, glacier melt, and sea ice changes are all well within the range of natural variation for the Arctic region. The changes that do occur have identifiable origins that are unrelated to atmospheric CO2 concentrations or human emissions.
Below is a brief summary of some of the latest research that underscores the lack of connection between anthropogenic influences and climate-related changes in the Arctic.

Climate Change Weather Disables US Navy’s Newest Ship!
Brand-new US Navy warship trapped in Canada amid cold and ice
A brand-new U.S. Navy warship has not moved from Montreal since Christmas Eve and will spend the winter stuck in Canada due to cold and ice.
The USS Little Rock – unveiled in a ceremony on Dec. 16 in Buffalo, New York and attended by nearly 9,000 people – has not moved far since due to adverse weather conditions that kept the warship trapped at bay in Canada, the Toronto Star reported.
The warship known as a Littoral Combat Ship (LCS) cost $440 million to build and stretches 387 feet in length and weighs 15 tons more than the Statue of Liberty. It is capable of traveling more than 46 miles per hour.
Such combat ships are described as agile and designed for rapid…

In scanning comments generated by the recent flurry of internet interest in polar bears and blogs I noticed that a good many people, fed alarming media stories, are still convinced that polar bear numbers are declining rapidly when nothing could be further from the truth.
In some cases, the media have made a possible future problem sound like a current problem. In others, people are remembering data from 2010 or so, not realizing that the picture has changed — or they assume that a conservation status of ‘threatened’ or ‘vulnerable’ (e.g. Amstrup et al. 2007) must mean numbers are declining (because that’s true for virtually all species classified that way, except polar bears).
The sea ice situation hasn’t really improved or deteriorated since 2007 but the polar bear picture is much better: there is information on more subpopulations and studies show most are holding stable or increasing (Aars et…

“Sooner or later we all sit down to a banquet of consequences.” – Robert Louis Stevenson
AND I don’t mean the Russians or their busted thermometer. I mean the temperature manipulators at NASA GISS, NOAA, BoM et al., and the sycophant mainstream, climate-obsessed media who spruik their “Super-Hot Arctic”, “Hottest Year Evah” pseudoscientific propaganda PR BS.
The thermometer in a remote Siberian village known as the coldest inhabited place on earth has broken as temperatures plunged to near-record depths, reports the Daily Telegraph.
The public device, which was installed in Oymyakon as a tourist attraction, recorded -62C, before malfunctioning this week.
Meanwhile the Siberian Times reports that some locals had readings as low as -67C – in touching distance of the record -67.7C, which was logged in the village in February 1933.

AN IMPORTANT and timely read Via The Times – MATT RIDLEY (Climatism bolds)
RECORD cold in America has brought temperatures as low as minus 44C in North Dakota, frozen sharks in Massachusetts and iguanas falling from trees in Florida. Al Gore blames global warming, citing one scientist to the effect that this is “exactly what we should expect from the climate crisis”. Others beg to differ: Kevin Trenberth, of America’s National Centre for Atmospheric Research, insists that “winter storms are a manifestation of winter, not climate change”.
Forty-five years ago a run of cold winters caused a “global cooling” scare. “A global deterioration of the climate, by order of magnitude larger than any hitherto experienced by civilised mankind, is a very real possibility and indeed may be due very soon,” read a letter to President Nixon in 1972 from two scientists reporting the views of 42 “top” colleagues. “The cooling has natural causes and falls within the rank of the processes which caused the last ice age.” The administration replied that it was “seized of the matter”.
In the years that followed, newspapers, magazines and television documentaries spoke of the coming ice age. The CIA reported a “growing consensus among leading climatologists that the world is undergoing a cooling trend”.
This alarm about global cooling is largely been forgotten, but it has not entirely gone away. Valentina Zharkova of Northumbria University has suggested that a quiescent sun presages another Little Ice Age like that of 1300-1850. I’m not persuaded. Yet the argument that the world is slowly slipping back into a proper ice age after 10,000 years of balmy warmth is in essence true. Most interglacial periods, or times without large ice sheets, last about that long, and ice cores from Greenland show that each of the past three millennia was cooler than the one before.
However, those ice cores, and others from Antarctica, can now put our minds to rest. They reveal that interglacials start abruptly with sudden and rapid warming but end gradually with many thousands of years of slow and erratic cooling. They have also begun to clarify the cause. It is a story that reminds us how vulnerable our civilisation is. If we aspire to keep the show on the road for another 10,000 years, we will have to understand ice ages.
The oldest explanation for the coming and going of ice was based on carbon dioxide. In 1895 the Swede Svante Arrhenius, one of the scientists who first championed the greenhouse theory, suggested that the ice retreated because carbon dioxide levels rose, and advanced because they fell. If this were true, then industrial emissions could head off the next ice age. There is indeed a correlation in the ice cores between temperature and carbon dioxide, but inconveniently it is the wrong way round: carbon dioxide follows rather than leads temperature downward when the ice returns.
A Serbian named Milutin Milankovich, writing in 1941, argued that ice ages and interglacials were instead caused by changes in the orbit of the Earth around the sun. These changes, known as eccentricity, obliquity and precession, sometimes combined to increase the relative warmth of northern hemisphere summers, melting ice caps in North America and Eurasia and spreading warmth worldwide.
IN 1976 Nicholas Shackleton, a Cambridge physicist, and his colleagues published evidence from deep-sea cores of cycles in the warming and cooling of the Earth over the past half million years which fitted Milankovich’s orbital wobbles. Precession, which decides whether the Earth is closer to the sun in July or in January, is on a 23,000-year cycle; obliquity, which decides how tilted the axis of the Earth is and therefore how warm the summer is, is on a 41,000-year cycle; and eccentricity, which decides how rounded or elongated the Earth’s orbit is and therefore how close to the sun the planet gets, is on a 100,000-year cycle. When these combine to make a “great summer” in the north, the ice caps shrink.
Game, set and match to Milankovich? Not quite. The Antarctic ice cores, going back 800,000 years, then revealed that there were some great summers when the Milankovich wobbles should have produced an interglacial warming, but did not. To explain these “missing interglacials”, a recent paper in Geoscience Frontiers by Ralph Ellis and Michael Palmer argues we need carbon dioxide back on the stage, not as a greenhouse gas but as plant food.
The argument goes like this. Colder oceans evaporate less moisture and rainfall decreases. At the depth of the last ice age, Africa suffered long mega-droughts; only small pockets of rainforest remained. Crucially, the longer an ice age lasts, the more carbon dioxide is dissolved in the cold oceans. When the level of carbon dioxide in the atmosphere drops below 200 parts per million (0.02 per cent), plants struggle to grow at all, especially at high altitudes. Deserts expand. Dust storms grow more frequent and larger. In the Antarctic ice cores, dust increased markedly whenever carbon dioxide levels went below 200 ppm. The dust would have begun to accumulate on the ice caps, especially those of Eurasia and North America, which were close to deserts. Next time a Milankovich great summer came along, and the ice caps began to melt, the ice would have grown dirtier and dirtier, years of deposited dust coming together as the ice shrank. The darker ice would have absorbed more heat from the sun and a runaway process of collapsing ice caps would have begun.
All of human civilisation happened in an interglacial period, with a relatively stable climate, plentiful rainfall and high enough levels of carbon dioxide to allow the vigorous growth of plants. Agriculture was probably impossible before then, and without its hugely expanded energy supply, none of the subsequent flowering of human culture would have happened.
That interglacial will end. Today the northern summer sunshine is again slightly weaker than the southern. In a few tens of thousands of years, our descendants will probably be struggling with volatile weather, dust storms and air that cannot support many crops. But that is a very long way off, and by then technology should be more advanced, unless we prevent it developing. The key will be energy. With plentiful and cheap energy our successors could thrive even in a future ice age, growing crops, watering deserts, maintaining rainforests and even melting ice caps.

“A bit of reflection shows it was the climate science community itself — in collaboration with Arctic researchers and the media — who by the year 2000 (below left) set the polar bear up as an icon for catastrophic global warming. They made the polar bear a proxy for AGW.”
YET ANOTHER failed prediction from the catastrophic climate change cabal!
“This has left many folks unhappy about the toppling of this important global warming icon but ironically, consensus polar bear experts and climate scientists (and their supporters) were the ones who set up the polar bear as a proxy for AGW in the first place.”
Polar bear experts who falsely predicted that roughly 17,300 polar bearswould be dead by now (given sea ice conditions since 2007) have realized their failure has not only kicked their own credibility to the curb, it has taken with it the reputations of their climate change colleagues. This has left many folks unhappy about the toppling of this important global warming icon but ironically, consensus polar bear experts and climate scientists (and their supporters) were the ones who set up the polar bear as a proxy for AGW in the first place.
I published my professional criticisms on the failed predictions of the polar bear conservation community in a professional online scientific preprint journal, which has now been downloaded almost 2,000 times (Crockford 2017; Crockford and Geist 2017).
My paper demonstrates that the polar bear/seaice decline hypothesis, particularly the one developed by Steven Amstrup, is a failure. I’m not…

One thing that has fascinated me, in my study of sea-ice, is how swiftly vast areas can freeze over. This is apparent from many sources.
The captains of whaling ships, tempted north by whale’s habit of hunting in the rich ecosystem that exists at the very edge of the ice, sometimes appear like cowards for turning tail and fleeing the refreeze far before the whales chose to depart. (You might think whales would know best when to depart, for they suffocate when trapped under ice). However this choice does not seem so foolish once you understand larger whales could break up through a foot of ice, (with smaller beluga whales following and using the air-holes big whales created), while, without a strong following wind, a sailing craft could be bogged down and halted by a skim of ice only an inch thick. And despite all precautions, the ice formed so…
