New Paper Indicates There Is More Arctic Sea Ice Now Than For Nearly All Of The Last 10,000 Years. By Kenneth Richard on 2. March 2017 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.

Of note, the paper makes no reference to carbon dioxide or anthropogenic forcing as factors modulating Arctic sea ice. Stein et al., 2017 The causes that are controlling the decrease in sea ice are still under discussion. Lessen and Thejll, 2005. Massive Growth In Thick Arctic Sea Ice | The Deplorable Climate Science Blog. Over the past nine years, there has been a huge increase in the area of thick Arctic sea ice. The Chukchi and East Siberian Seas had no thick ice in 2008, but lots of it now. DMI Modelled ice thickness Government experts of course claim the exact opposite, because they are paid to lie – or at least they were until January 20th.

Historic Variation in Arctic Ice Guest post from the Air Vent by Tony B The following is a guest post by Tony B on the history of Arctic ice. I nominated him Arctic ice historian on WUWT when I noticed he had done a considerable amount of research. Happily he took me up on it and has put a lot of work into this.

I don’t know his full background, but I think you’ll see he has an excellent grasp of the historic nature of sea ice in the Arctic. I hope you enjoy it as much as I did. I placed most of the images in myself from Tony’s references.

Guest essay by Tony brown Foreword Note; Last year an edited version of this article appeared at Climate Etc. This new version contains numerous additional references, graphics, quotes, more historic detail and updates. ‘Historic variations in Arctic Ice’ is a series of articles that attempts to determine the arctic warming events through the Holocene which commenced some 11000 years ago. (See Graphic ‘after Dansgaard et al’ below. After Dansgaard et al.

This paper- Part 2–examines the period of warming 1920-1940 in detail with a decade long overlap. Part 3 will examine the evidence for other episodes of warming through the Holocene.

By Paul Homewood As I pointed out in my post, Arctic Sea Ice Update, the other day, we currently have low sea ice extent and unusually high temperature anomalies in the Arctic.

Although much of this is just weather, there is an underlying pattern of warming related to pulses of unusually warm water, which have been entering the Arctic Ocean from the Atlantic for the last decade or more. But just how unusual are conditions there? Are they as unprecedented as Neven suggested in the comments? The area we are talking about spans from East Greenland across to Siberia. So what do the temperature trends tell us about the climate in that part of the world. Akureyri in Iceland is regarded as being the Icelandic site most representative of climate in the Greenland Sea, as it is on the north coast. I prepared this graph of annual mean temperatures a few months ago. The warmest year recently was 2014, with a mean of 5.3C. Like this: Honey, I Shrunk the Arctic Ice! Not. | Science Matters.

The notion that man-made global warming causes Arctic ice to melt took a major hit with a recent publication. The article is Influence of high-latitude atmospheric circulation changes on summertime Arctic sea ice by Qinghua Ding, Axel Schweiger, Michelle L’Heureux, David S. Battisti, Stephen Po-Chedley, Nathaniel C. Johnson, Eduardo Blanchard-Wrigglesworth, Kirstin Harnos, Qin Zhang, Ryan Eastman & Eric J. The paper was published online by Nature Climate Change on 13 March 2017. The Arctic has seen rapid sea-ice decline in the past three decades, whilst warming at about twice the global average rate. Announcements of the finding were welcomed by skeptics and lukewarmists as an indication that climatologists were taking off their CO2 blinders and at last admitting to natural forces internal to the climate system. Arctic Ice Loss Driven by Natural Swings What Ding et al.

Nature, not humans, could be cause of up to half of Arctic sea ice loss, study claims | The Independent. Natural processes may be responsible for up to half the dramatic decline in sea ice in the Arctic over the last four decades, according to a new study. While air currents had been affected by human-induced climate change, most of the changes were the result of an internal variability within the system over several decades, the researchers found.

And they estimated these natural fluctuations were responsible for between 30 and 50 per cent of the sea ice loss since 1979. Other climate scientists said the study helped explained why their computer models had underestimated the reduction in sea ice compared to what has actually happened in the region. Sea ice in the Arctic and Antarctic has been hitting record lows in recent months. The loss of sea ice is believed to be accelerating global warming, because white ice reflects the sun's heat back out to space, while dark water absorbs it. “We do know that global warming, anthropogenic forcing, will have some effect on the circulation,” he said. Visualizing Government Arctic Sea Ice Fraud | The Deplorable Climate Science Blog. “It is difficult to get a man to understand something, when his salary depends upon his not understanding it.”– Upton Sinclair Government agencies like NOAA, NASA and NSIDC start their sea ice graphs in 1979, in order to make it look like there is a linear decline in sea ice.

NOAA claims they don’t have satellite data before 1979, but they are lying. The 1990 IPCC report showed NOAA satellite data back to 1973, which was much lower than 1979. 1990 IPCC Report In fact, there is reasonably good ice data going back to the 1920’s, which shows that ice extent was very low in the 1940’s and 1950’s.

Researchers found that ice conditions in the 19th century were remarkably similar to today’s, observations falling within normal variability. Overview This article demonstrates the use of historical instrument and descriptive records to assess the hypothesis that environmental conditions observed by 19th-century explorers in the Canadian archipelago were consistent with a Little Ice Age as evident in proxy records. It is clear that the first-hand observations of 19th-century explorers are not consistent with the hypothesized severe conditions of a multi-decadal Little Ice Age. Analysis There were more than seventy expeditions or scientific enterprises of various types dispatched to the Canadian Arctic in the period between 1818 and 1910. Fig.1. Fig.2.

Locations of arctic stations examined in this study An recent extensive analysis of Northern surface temperature records gives no support for Arctic “amplification” fears. The Arctic has warmed at the same rate as Europe over the past two centuries. Heretofore, it has been supposed that any global warming would be amplified in the Arctic. This may still be true if urban heat island effects are responsible for part of the observed temperature increase at European stations.

However, European and Arctic temperatures have remained closely synchronized for over 200 years during the rapid growth of urban centres. And the warming pattern in Europe and the Arctic is familiar and unalarming. Arctic temperatures have increased during the period 1820– 2014.
