Have Things Changed Much From 1969?

Expert Says Arctic Ocean Will Soon Be an Open Sea; Catastrophic Shifts in Climate Feared if Change Occurs“. Yes, it’s 1969.

What else has changed?

Well, one thing is that at the time, Walter Sullivan of the New York Times could still afford to write “Other Specialists See No Thinning of Polar Ice Cap” in mid-size letters near the title. As for the rest:

  • Arctic sea ice cover is “vulnerable
  • An ice-free Arctic Ocean is presented as harbinger of European “deserts” with “great ice sheets…farther north
  • Focal point” in the research is “the use of giant computers to simulate the world’s weather patterns
  • Climatologists keep following the latest trends, wildly extrapolating them in the future. For example, there is a Soviet-American consensus among specialists around prediction of “continued cooling in step with an expected decline in sunspot activity through the nineteen-eighties“, after a “climate cooling during the last decade or two“. Likewise, “until recently there was a suspicion that the warming trend of the century preceding 1940 was a by-product of the industrial revolution” (yes, CO2 emissions)

However, there are other interesting details:

  • Sullivan presents as common knowledge ideas such as “progressive shrinkage of the Arctic pack ice over the last century
  • About one quarter of the Arctic pack melts each summer“…that would be very peculiar, since according to Cryosphere Today even in 1979 it was more like two thirds
  • Nortber Untersteiner is interviewed about a report of his in Naval Research Reviews showing that “the climatic trend in the Arctic has turned toward cooling
  • There is a mention of a 1893 Fridtjof Nansen report of “43 feet thick” Arctic pack, followed by others “indicating a steady thinning of the pack that, the data suggest, could vanish by 1970 or sooner“. These conclusions are not supported by “under-ice journeys of American nuclear submarines” (why don’t they use submarines nowadays, instead of clowning around for Catlin?)
