The pattern suggests that the world has entered a period of
slight cooling until about 2030.
So far that plot has been quite effective in predicting (a)
slight cooling until 2028 and (b) a long - term maximum approaching within 200 years at the most, with an increase of no more than about 0.8 C degree in the long - term trend by that maximum.

It is to be noted here that there is no necessary contradiction between forecast expectations of (a) some renewed (or continuation of)
slight cooling of world climate for a few decades to come, e.g., from volcanic or solar activity variations; (b) an abrupt warming due to the effect of increasing carbon dioxide, lasting some centuries
until fossil fuels are exhausted and a while thereafter; and this followed in turn by (c) a glaciation lasting (like the previous ones) for many thousands of years.»
