The Arctic is the most sensitive place to man-made emissions on Earth, which is why it has barely warmed since 1944? Well, it makes sense if CO2 is largely irrelevant. Humans have made 90% of all their CO2 in the last 70 years and nothing much happened in the place where it was supposed to hurt the most.
The WMO apparently missed the first 30 years of data. But Dr. Sebastian Lüning and Prof. Fritz Vahrenholt are here to help them out. : -)
“Heat waves in the Arctic – climate scientists sound the alarm“
Area weighted Arctic (70-90N) monthly surface air temperature anomalies (HadCRUT4) since 1920 in relation to the WMO normal period 1961-1990. Fig. 2: Arctic temperature since 1920. Data: HadCRUT4, Chart: Climate4You.
These heat waves look a lot like the last heat waves.
