Nobody born since 1976 has experienced a colder-than-average year.
My mother’s childhood was spent in a world that rarely reached the 20th Century average temperature. She once saw the Fraser River frozen at New Westminster. My childhood was spent in a world with temperatures dead on the 20th Century average. My son was born in 1976. He has never experienced a single year as cool as the ones my mother grew up with, and has barely known the climate I grew up in.
That’s like moving from Sudbury to Hamilton. It is like moving from San Francisco to Los Angelos.
Note: There are slight differences among the results form different climate study groups. Each group calculates global temperature year by year, using slightly different techniques. However, analyses from all three groups point to the decade between 2000 and 2009 as the hottest since modern records began more than a century ago. Temperatures in the 2010s have been running slightly warmer still.
