Southeast Greenland Sea Surface Temperature 1° – 2°C Warmer In 1940 Than Today, New Study Shows

Southeast Greenland sea surface temperature was warmer than today in the 1940s, 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 claiming the present is warmer than at any time in the past 1000 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.

Why would they need cores?

The navies of the world have been plying those waters for centuries, and they've been using steam driven ships since before the Titanic.

Steam ships typically use a condenser to recycle the fresh water back to the boiler, and those use sea water.   Depending on when they started keeping records, the engine room lower level watches of those ships have been recording sea water intake temps for years and years.  Wouldn't take much of a study to dig out where and when and how cold the water was over significant parts of the northern seas.
