First off, the trend line on that graph is clearly upwards. You can’t cherry pick one outlier data point as the starting point and then say that anything below that point doesn’t matter. This is clearly trolling behavior at best.
Secondly, I’m not sure where you found this graph but it’s clearly been chosen specifically because of the height of the 1998 outlier. A graph including the whole earth and all data available does not show the same strong peak. So this is again, prevarication at best.

And where did I claim that?
Both RSS and UAH show this same peak. This is a well known fact to anybody who's following satellite temperature measurements.
The graph starts in 79 because UAH didn't exist before that time.

You may mean giss which is a different measurement method based on ground measurement stations, not the "whole earth". It shows a less pronounced peak, yes.
