Changes in thermal indices on Herschel Island (Qikiqtaruk), Canada between the periods 1899–1905 and 2008–2014
The paper provides a comparison of minimum air temperature (TN), maximum air temperature (TX), mean air temperature (T mean) and a few derived temperature indices for Herschel Island (Qikiqtaruk) in the Yukon Territory, Canada for the periods 1899–1905 and 2008–2014. A significant increase in the TN...

Air temperature increased the most in October, November, and December. In addition, the length of the frost-free season increased by 26 days and the length of the growing season increased by 25 days from the early 20th century to the early 21st century.
