CBC Claims Canada Warming Twice As Fast As Globe, Yet Data Tell A Different Story: No Warming In 25 Years!
Canada’s CBC here recently cited “a leaked report” which claimed Canada is “warming at twice the global rate.”
According to the “leaked report”, Canada’s annual average temperature over land has warmed 1.7 C when looking at the data since 1948. But that claim is misleading when recent data is considered.
Over the past 25 years, since scientists began to warn that the planet was warming in earnest, there has not been any warming when one looks at the untampered data provided by the Japan meteorology Agency (JMA) that were measured by 9 different stations across Canada. These 9 stations have the data dating back to around 1983 or 1986, so I used their datasats.
Looking at the JMA database and plotting the stations with longer term recording, we have the following chart:
Data source: JMA.
Though temperatures over Canada no doubt have risen over the past century, there has not been any real warming in over 25 years. Rather, there’s been slight cooling, though not statistically significant. Clearly there hasn’t been any Canadian warming recently.
So it is misleading — to say the least — to give the impression that Canada warming has been accelerating.
