Over the last decade the surface temperatures of the earth have increased. During the previous decades, the surface temperatures of the earth increased at a somewhat higher rate. Meanwhile, over the last decade there seems to be some extra heat gain in the deeper ocean. Also, some of the surface heat is busy melting the planet's glaciers and the Arctic Sea ice. That heat does not contribute to the surface heat measurement. So, global warming has not slowed down.
This is what we know.
Here is a nice video that explains some of this from the Yale Climate Forum, made by Peter Sinclair.
