HH Lamb & Cooling In The Arctic
By Paul Homewood
HH Lamb, in “Climate, History & The Modern World” had this to say about the state of the Arctic in the 1960’s and 70’s.
This is from the Chapter “ CLIMATE SINCE 1950”.
ANOTHER TURNING POINT
Over the years since the 1940’s it has become apparent that many of the tendencies in world climate which marked the previous 50 to 80 years or more have either ceased or changed. It is undoubtedly this that has stimulated interest in climate and increased effort in climatic research in recent years. It was only after the end of the Second World War that the benign trend of the climate towards general warming over those previous decades really came in for much scientific discussion and began to attract public notice.
Attention at that time was focused on where continuation of the trend might lead: on the possible disappearance of the Arctic sea ice by the end of the century, and what effect that might have on agriculture…..
COOLING IN THE ARCTIC
The cooling of the Arctic since 1950-60 [bear in mind the book was published in 1982] has been most marked in the very same regions which experienced the strongest warming in the earlier decades of the 20thC, namely the central Arctic and northernmost parts of the two great continents remote from the world’s oceans, but also in the Norwegian-East Greenland Sea….
A greatly increased flow of the cold East Greenland Current has in several years (especially 1968 and 1969, but also 1965, 1975 and 1979) brought more Arctic sea ice to the coasts of Iceland than for fifty years. In April-May 1968 and 1969, the island was half surrounded by ice, as had not occurred since 1888.
Such sea ice years have always been dreaded in Iceland’s history because of the depression of summer temperatures and the effects on farm production….. The 1960’s also saw the abandonment of attempts at grain growing in Iceland, which had been resumed in the warmer decades of this century after a lapse of some hundreds of years…
Let me finish with this graph showing variation of Arctic sea ice around the coast of Iceland since 800 AD.
It shows the huge expansion of ice during the LIA, and also puts into perspective the warmer 1930’s and 40’s, when temperatures in Iceland were similar to now, which still had more ice than during most of the MWP.
Above all it shows the sharp increase in ice coverage during the 1955-75 period.
Anybody who suggests we should only concern ourselves with Arctic sea ice trends since satellites began to monitor in 1979 either does not know what he is talking about, or is being dishonest.
