Well, both sides are right on that one, because it's not happening.
The research, carried out by an international team of scientists including the University of Sheffield, has found that warming in the Arctic may be intensifying the effects of the jet stream's position, which in the winter can cause extreme cold weather, such as the winter of 2014/15 which saw record snowfall levels in New York.Scientists previously had two schools of thought. One group believe that natural variability in the jet stream's position has caused the recent severe cold winter weather seen in places such as the Eastern United States and the UK. The other camp includes scientists who are finding possible connections between the warming of the Arctic - such as melting sea ice, warming air temperatures, and rising sea surface temperatures - and the emerging pattern of severe cold winter weather.
Scientists have been divided over the cause of recent cold winters. One camp believes they are merely the result of natural jet stream variability, but the other is convinced there is a connection with global warming.

colder winters (with more snow of course).
Actual scientist know that mid latitude NH winters have been getting colder (not the arctic for the most part) , and they are in different camps.

No real scientists ignores the data, which clearly shows the NH winters have been trending colder. With more snow.
The Blue Hill data is one of those rare stations that isn't that adjusted (by NOAA or NASA), because they have been careful and scientific and even more importantly, the data shows long term annual warming, with out the need to adjust the past.
The extensive research Blue Hill has done with the data does show how the new electronic sensors bias the data, but it makes the daytime high higher, not lower. Because the electronic sensors will record very brief transient highs, the ASOS data records a brief warm event as the daily high, which means the Tmax data from the new equipment has a warm bias, which of course makes the daily mean higher.
The Blue Hill data is GHCND:USC00190736https://www.ncdc.noaa.gov/cdo-web/datasets/GHCND/stations/GHCND:USC00190736/detail
If so, is there a more direct link to it?
Okay, let's take it as read that that's what you did. What might explain the difference between the values on the graph and the ones reported on Blue Hill's website?
