Sometimes I get old scientific papers emailed to me. This one is from 2008, but I have not come across it before, and it is still highly relevant:
Below is the key finding:
There has been a marked decline in SSTs since the MWP, with them dropping to the lowest in the 4500 year series.
It should be pointed out that this particular core is expressed as years before 1950.
Another core gives more recent data, clearly showing the Great Salinity Anomaly (GSA) in the 1960s, which marked the shift to a drastically colder climate in Iceland at the time:
Although this study only looks at one small area off the North Iceland coast, it is one which is important in understanding Arctic climate, as it a place where various major ocean currents interact. It is therefore instrumental in the advance or retreat of the polar front.
These findings support conclusions from many other sources. that the Arctic climate is not unusually warm now, indeed by historical standards it is colder than normal. Our perception is skewed because we are viewing it through the lens of the Little Ice Age.
