A couple of caveats:
These are measurements made by satellite over land. Lower troposphere temperatures recorded by satellite have never shown the same rise in temperatures as the so-called and oft-quoted global temperatures (supposedly a combination of land and sea-based direct measurements AIUI), over the period 1975-2000.
We are going into a La Niña period, following a particularly strong El Niño 2015/16.
Those caveats notwithstanding, this comment is noteworthy "According to satellite data, the late 2016 temperatures are returning to the levels they were at after the 1998 El Nino." So the temperatures are flat-lining, as can be seen from the graph.
