This is a misleading summary - global emissions may be about to peak (mainly due to changes in China), however planetary damage will lag way beyond that. As emissions peak, concentration increase will slow down (point of inflection), and even if concentration eventually peaks (before emissions approach net zero) surface temperature rise will lag a few decades behind that, while the deep ocean temperature and ice-melt and consequent sea-level rise could still continue for a century or more.
You need a model, not data, to get the inertia in the system (- here's mine you can experiment)
