Indications Of A Changing Arctic (Across The Centuries)

(h/t FM)

Is there anything peculiar happening in the Arctic in our time? Unfortunately, satellite-based sea-ice measurements only start from 1979, i.e. have just barely crossed the magic 30-year line that we’re told separates “weather” from “climate” (in other words, we have just been able to say that, according to mainstream climatology, the ice in 1995 was on the decrease).

A different way to look at the issue is to source information from relatively old books and newspaper articles. And there are good indications that their analysis will show quite large changes in the Arctic sea-ice extension across the centuries.

As it happens, I was sent yesterday the link to a very interesting  1818 compendium edition of mid-1770’s North-Pole-related thoughts and reports by Danies Barrington FRS of “young Mozart” fame: “The Possibility of Approaching the North Pole Asserted“.

Barrington goes at great length both in collecting as much evidence as possible from seamen claiming to have been further North than would have been expected; and in examining such evidence with a healthy dose of skepticism. His conclusions: several ships have been beyond 82N, and many of them have reported clear water to the North (see page 61). And yes, uncertainties were put in plain sight: finding a way to reach Asia without going around the tip of South America was considered very serious business, and even a strong advocate for Polar exploration like Barrington didn’t try to hide what he might have found uncomfortable. A quarter of a millennium later, we can be fairly certain ships at Barrington’s time were regularly reaching 81N.

Fast forward to 1858 and a “letter” on the New York Times by a Col. Peter Force, actually the text of a lecture at the New-York Historical Society on July 1st of that year. Col. Force appears extremely skeptical of any claim about the very existence of a Northwest Passage, going as far as to use that old saying, “if it were there we would have discovered it by now”. And if you look at the details reported, the 82N of 80 years earlier was then almost an unreachable goal, as there is plenty of mentions of sea ice going as low as 69N.

Arctic sea ice was therefore extending much further to the South in 1858 than in 1775. But were the CO2 emissions in 1775 higher than in 1858? I do not think so.

    Wonderful article! Send it to Moonbat, Anthony Giddens, the BBC and the Royal Society (although they must surely have a copy of 1818 compendium edition of mid-1770′s North-Pole-related thoughts and reports by Danies Barrington in their archives).
