Still on course for 1.5°C warmer by 2033
The November CRUTEM global temperatures have been released. They show the 12 month moving average of global temperatures is still rebounding upwards, but you would expect the steepness of this rise to slacken off as we go into 2020. The latest 10 year linear trend (2010-2019 red dashed line) is showing a trend of +0.279°C per decade, if that rise continues unchecked global temperatures will cross the 1.5°C higher than in pre-industrial times threshold by 2033. The 30 year linear trend (1990-2019 blue dashed line), with it’s more modest rise of +0.171°C per decade, is 11 years slower.
