Is it a pause?
While the heat is channeled away from the atmosphere, the paper suggests that it is causing increased warming of the Atlantic ocean.

If this process is cyclical & has historically caused a cooling period, the fact that global average temperatures have continued to rise, albeit more slowly, does not bode well for when this cycle ends.
Heat energy can do many things besides increase temperature - phase change for example - just because we don't immediately see a temperature effect of the energy does not mean that the process has stopped - Ro
World's Largest Ice Sheets Melting At Fastest Rate Ever Recorded

Greenland and Antarctica are home to the two largest ice sheets in the world, and a new report released Wednesday says that they are contributing to sea level rise twice as much as they were just five years ago.
Using the European Space Agency's CryoSat 2 satellite, the Alfred Wegener Institute from Germany has found that western Antarctica and Greenland are losing massive amounts of ice.
"Combined, the two ice sheets are thinning at a rate of 500 cubic kilometres per year," said glaciologist Dr. Angelika Humbert, one of the authors of the AWI study, in a press release. "That is the highest speed observed since altimetry satellite records began about 20 years ago."

"Pause" is a meme promulgated by the denier camp. One that is unsupported by actual data.
Have been musing on how a large volcanic event in Iceland would impact the current climate change process. In the absence of humans the eruption would cause climate cooling in terms of the albedo effect (like nuclear winter - sun photons and IR do not penetrate an ash covered atmosphere well) and then a greenhouse effect would kick in as the ash clears and sun energy is trapped inside the atmosphere by greenhouse gasses from the volcano. Add back in humans - our oceans hold tremendous amounts of excess heat now. Not sure it would be of much help to plant life tho if photon penetration is reduced enough to impair most photosynthesis. Once the ash clears then not only will we have the greenhouse gasses from the eruption but also our currently overheating planet. I think it could bring on a serious pendulum swing that would challenge even the most enterprising of extremophiles. (We, in case you dont know, are not extremophiles).

I think that article title should have used the term 'hiatus' or slowdown rather than pause. It references a BBC article that says:
So that is a dramatic slowdown, in spite of increasing CO2 levels. Yet the Arctic ice is still melting and that may be why NASA is starting the new study I posted about. I suspect black carbon is the real driver of ice melting and its effect on climate change. But then I'm biased since I can suffer from woodsmoke pollution every winter.
