Global cooling: is the paper really claiming it?

A recent paper in Nature finds a strong correlation between ocean circulation and oscillations in Atlantic surface temperatures which could be moving to a negative phase. According to the authors, "[t]his may offer a brief respite from the persistent rise of global temperatures."

This claim has been taken up by various sites, along a much stronger prediction: decades of global cooling by up to 0.5°C. However, I cannot find this second item anywhere in the original paper. Where does it come from?!
