November 2019 sees global temperature above Bet warming line

without comments

With the release of the UAH November 2019 global temperature anomaly, there have been 28 months in which the anomaly equaled or exceeded the 3°C-per-century warming trend line projected from the 2007 Bet base year average. That compares with the 57 months in which the anomaly has been less than or equal to the scientific no-change forecast proposed by Green, Armstrong, and Soon (2009) and the basis of Scott Armstrong’s challenge to Al Gore to bet on forecasts of global temperatures.

Those figures give a sense of how modest the IPCC’s 3°C-per-century warming trend is compared to month-to-month variations over the 143 months (nearly 12 years) of the extended Bet so far. The 28 months of temperature anomalies greater than or equal to the warming trend account for nearly 20% of months, while close to 40% of months have been cooler than the 2007 base year average.
