Warming In The Arctic Has Happened Before – Cambridge Bay Nunavut

Some blogger named David Appell was sounding the AGW alarm yesterday (for the millionth time I think)  about dangerous Arctic Greening.

Aside from the fact that greening is probably a good thing and that greening may be caused by more CO2 (a plant food) and not necessarily warming I also thought I would take a look at some Environment Canada weather stations in the north.

One of the stations with a long data record is Cambridge Bay Airport in Nunavut. The temperature anomalies are in relation to the 1971 – 2000 average.

The temperature in the boxes is the 5 year average. While it is true the temperature is 2.5C or so warmer than around 1980, it is also true it is only 1.2C warmer than around 1940. And who knows if the 20s or 30s were warmer or colder? Not enough data.

Do note that around 1965 it was 1.8C colder than the 1930s/40s.

All Data - CAMBRIDGE BAY A - Environment Canada as of  February 2013

Since the latest data is from February, I thought I would show the warmest and coldest February’s for Cambridge Bay Airport.

Notice that 1931 was 4th warmest. 1941 and 1940 and 1929 made the top 11. etc/
