Climate Zealots Cool-Shamed
As an icy winter spreads over the continental United States and Antarctic sea ice is growing, a deep chill has settled over the climate "scientists". The only shred of credibility to which they still cling is "climate change".
Since global warming is far too tendentious to maintain in the face of data like this, the cognoscenti created a new term to describe global warming--a term deliberately intended to put the global warming theory beyond any possibility of being proven false. Since every climate changes and varies all the time, any--we repeat, any climatic conditions now "prove" global warming. They "prove" climate change, and climate change is aka global warming. Ergo, the science is settled. The world is definitely warming up.
There are at least two lines of argument that potentially falsify global warming ideology. The first is to research temperatures one hundred or more years ago. If these can be shown to be as warm, or higher, than today's temperatures, then the hypothesis that temperatures are rising (due to man's rape and pillage of the earth's environment) would be falsified, or proven wrong.
The second line of argument falsifying the man-caused global warming hypothesis is to prove or establish that the climate has not been warming in recent times when compared to older records. Hence, record cold temperatures in the United States this year are a pain in the proverbial for global warming ideologues. According to their pet theory, this should not be happening.
In this great debate, historical temperature records are significant and important data.
The extent of sea ice at the poles is also significant. It turns out that one hundred years ago, intrepid Antarctic explorers were pretty careful observers of climatic conditions at the South Pole. And the results of their measurement and observations? It was pretty warm down there (comparatively) one hundred years ago. The hypothesis of anthropogenic (man caused) global warming is teetering on the edge of being proven false.

Scott and Shackleton logbooks prove Antarctic sea ice is not shrinking 100 years after expeditions

Antarctic sea ice had barely changed from where it was 100 years ago, scientists have discovered, after poring over the logbooks of great polar explorers such as Robert Falcon Scott and Ernest Shackleton.
Experts were concerned that ice at the South Pole had declined significantly since the 1950s, which they feared was driven by man-made climate change. But new analysis suggests that conditions are now virtually identical to when the Terra Nova and Endurance sailed to the continent in the early 1900s, indicating that declines are part of a natural cycle and not the result of global warming. [Emphasis, ours.]
It also explains why sea ice levels in the South Pole have begun to rise again in recent years, a trend which has left climate scientists scratching their heads. "The missions of Scott and Shackleton are remembered in history as heroic failures, yet the data collected by these and other explorers could profoundly change the way we view the ebb and flow of Antarctic sea ice,” said Dr Jonathan Day, who led the study, which was published in the journal The Cryosphere.
"We know that sea ice in the Antarctic has increased slightly over the past 30 years, since satellite observations began. Scientists have been grappling to understand this trend in the context of global warming, but these new findings suggest it may not be anything new. If ice levels were as low a century ago as estimated in this research, then a similar increase may have occurred between then and the middle of the century, when previous studies suggest ice levels were far higher."
The study was based on the ice observations recorded in the logbooks from 11 voyages between 1897 and 1917, including three expeditions led by Captain Scott, two by Shackleton, as well as sea-ice records from Belgian, German and French missions. Captain Scott died along with his team in 1912 after losing to Norwegian Roald Amundsen in the race to the South Pole, while Shackleton's ship sank after becoming trapped in ice in 1915 as he and his crew attempted the first land crossing of Antarctica.
The study is the first to calculate sea ice in the period prior to the 1930s, and suggests the levels in the early 1900s were between 3.3 and 4.3 million square miles (5.3 and 7.4 million square kilometres). Estimates suggest Antarctic sea ice extent was significantly higher during the 1950s, before a steep decline returned it to around 3.7 million miles (6 million square kilometres) in recent decades which is just 14 per cent smaller than at the highest point of the 1900s and 12 per cent bigger than than the lowest point.
The findings demonstrate that the climate of Antarctica fluctuated significantly throughout the 20th century and indicates that sea ice in the Antarctic is much less sensitive to the effects of climate change than that of the Arctic, which has experienced a dramatic decline during the 20th century. In future the team plans to use data from naval and whaling ships as well as the logs from Amundsen’s expeditions to complete the picture.
Separate research by the British Antarctic Survey also showed that the present day loss of the Pine Island Glacier on the West Antarctic Ice Sheet has been happening since the mid 20th century and was probably caused by El Nino activity rather than global warming. [Emphasis, ours.]
Pine Island Glacier, which drains into the Amundsen Sea in West Antarctica, is retreating and thinning rapidly, but the initial triggering mechanism was unclear. The team looked at sediment cores in the area which showed that an ocean cavity under the ice shelf began to form around 1945, following a pulse of warmth associated with El Niño events in the tropical Pacific Ocean.
“We are very excited about this new finding as it provides the first direct evidence of the timing of glacier retreat even before we had satellites to measure them,” said lead author, marine geologist Dr James Smith from British Antarctic Survey. They show us how changes half-way across the planet in the tropical Pacific, reached through the ocean to influence the Antarctic ice sheet.”
Co-author Professor Bob Bindschadler of NASA added: “A significant implication of our findings is that once an ice sheet retreat is set in motion it can continue for decades, even if what started gets no worse. “It is possible that the changes we see today on Pine Island Glacier were essentially set in motion in the 1940s.” [So, not caused by mankind's industrialisation of the earth, then. Ed.]
The Pine Island research was published in Nature.
