Fascinating stuff. In the dataset can you see the precision of the recorded numbers. Was it to 1 decimal place or nearest whole number? Were they always in Celsius or originally Fahrenheit and converted to Celsius. Presumably in the days of bulb thermometers in wooden buckets, depth might have added to the variability.

I've not seen any original ship records but presume temp was recorded in whole units as Fahrenheit, and possibly written with quill pen! Variability would have been substantial.

Ivor Cummins posted a video to his YouTube channel about the Greenland Ice Core Project. It’s conclusions seem not to support the narrative. Temperatures observed in the ice cores reached a minimum in 1875, about the same time as modern meteorological records started.

Yep, GISP2 results throw a spanner in the works. Greenland's ice sheet will be the subject of a future article series.

Superb analysis and charts. What do you thing of the latest:

Enrico Ciracì, Eric Rignot, Bernd Scheuchl, Valentyn Tolpekin, Michael Wollersheim, Lu An, Pietro Milillo, Jose-Luis Bueso-Bello, Paola Rizzoli, Luigi Dini. Melt rates in the kilometer-size grounding zone of Petermann Glacier, Greenland, before and during a retreat. Proceedings of the National Academy of Sciences, 2023; 120 (20) DOI: 10.1073/pnas.2220924120

Thank you! I'd need time to study the paper. Glaciers can do very individual things, with some melting rapidly whilst others hardly change or even grow, so trying to nail a common global cause is a bit pointless. Formation of the glacier also impacts melt, as does stuff like particulate pollution, so in a way the destiny of this glacier was decided aeons ago.

I'm not sufficiently knowledgeable to judge, but my experience of reading studies in various subjects I do know about makes me think it is falsehoods camouflaged with gobbledygook. e.g. define a parameter that based on known data confirms the hypophysis, or fake the data.

Yes, sadly they play games these days in order to keep the grants flowing. I used to do the same back when a government scientist in order to keep my section of staff in employment.
