Southeast Greenland sea surface temperatures were warmer in the 1940s than today, scientists find.
A team of Danish scientists led by David Wangner published a paper a year ago about the results of a Greenland sediment core from Skjoldungen Fjord, near the Thrym Glacier, which allowed sea surface temperatures to be reconstructed.
The core covers the past 200 years (1796–2013). The scientists find that the SST record compares well with other alkenone‐based reconstructions from SE‐Greenland and thus features regional shelf water variability.
Today, some scientists like to claim the present is warmer than at any time in the past 1,000 years and suggest the Greenland ice sheets are rapidly melting.
But the results of the core reconstruction show that it was warmer in the past, some 80 years ago.
Warmer 80 years ago
The reconstructed SSTs in fact “show high amplitude fluctuations between 5°C and 12°C, especially during the 20th century.”
As the reconstructed sea surface temperatures in the area show, it was just as warm or warmer back in the 1940s. The period of 1915 – 1950 was at a similar level as today, thus nothing unusual is happening currently.
The authors also say that even though the meltwater production may have been influenced by climate, the glacier margin position and iceberg calving remained relatively constant in the 20th century.
Models poorly reflect Greenland
The Danish scientists are now requesting that Greenland glaciers be better taken into account in climate models and say that the unusual warmth of the early 20th century is related to a complex interaction between two major oceanic cycles: the AMO and the NAO.

The 1940s saw a period starting, following the warm 1930s, of record very cold and snowy UK winters up to about 1980, with newspapers reporting that satellite images showed a new little ice age was fast arriving. Amazing discovery: climate changes. Always did and always will.
And the Holocene Climate Optimum, the climate change that created human civilization, was warmer in summer than the current warm period.

More news and information that will be kept from the public. Can’t have us knowing what a sham the global warming hoax is.
The unusual warmth of the early 20th century may well be related to a complex interaction between two major oceanic cycles: the AMO and the NAO.
However, such things are subject to the complex interactions between the am and the nesia.
