Well your graph shows cooling of the oceans by 5/10 of one degree from 1880 to 1910. What process caused that cooling? I can only assume it was a natural process.
From about 1978 to now the oceans warmed about 6/10 of one degree. How much of that was a natural process?
What is the big deal?
Everyone seems to argue that every degree of warming today is due to climate change. In the past all warming and cooling was by a natural process but somehow no warming can be classed as natural. How can that be?
