Century of temperature

Whenever climate change is spoken of, the main focus is on temperatures increasing, causing the warming of the planet. Abisko’s 100 + years of temperature data tells the same story.

Whenever climate change is spoken of, the main focus is on temperatures increasing, causing the warming of the planet. Abisko had an arctic climate until the late 1990s, early 2000s, with an annual mean temperature at or below 0° C. Comparing one year to the next doesn’t tell us much about whether it’s getting warmer or colder – mean temperature has always differed between years. However, when we look at many years together (in climate research it is common to look at 30 year intervals) and compare the mean temperature of one year with the average temperature of all years, we can tell if it was a warmer or colder year than average. The following graphic shows clearly that almost all of the last 30 years were warmer than the long-term average (1913-1960).
