The count of degree*days freezing ends up between 5000 & 6400 (possible Temp =-1.8℃ -freezing point of seawater)
The count of degree*days thawing is less than 20 (above 0℃? - melting point of ice), yet the ice does not increase each summer!
These numbers are just a record of measurements/averages that MAY provide indications of a changing climate (currently -949 DDF for winter 2015/6). The elephant under the ice is warm water from the South (+ solar heating), which has managed to balance the freezing/thawing in spite of the very different measurements.
Neven, sorry, I should really have put this in the blog (Winter Analysis Addendum) but struggle to sign in!
