Stephen Briggs from the European Space Agency’s Directorate of Earth Observation says that sea surface temperature data is the worst indicator of global climate that can be used, describing it as “lousy”.
“It is like looking at the last hair on the tail of a dog and trying to decide what breed it is,” he said on Friday at the Royal Society in London.
“The models don’t have the skill we thought they had. That’s the problem,” admits Peter Jan van Leeuwen, director of the National Centre of Earth Observation at the University of Reading.
Obviously if the surface temperature was still rising, as it was in the 90s, instead of inconveniently contradicting model predictions, then it would still be considered a valid climate metric.
Thankfully however, climate scientists have not yet run out of metrics which show an upward trend. The new measure of global warming is to be sea level rise – presumably because it is still moving in the right direction, and because it ties in nicely with the “deep ocean heating” narrative.
