Pierre is the same person who, eight years ago in 2008, predicted that by 2020 the surface temperature would have dropped by 2.5 °C. That prediction isn't looking too hot right now. It would have to drop by 2.83 °C from 2015.

Pierre is as woeful at understanding science papers as he is at predicting global surface temperature.
