So
over a period of 138 years, the increase in the
YEARLY AVERAGE of the
temperature of the ENTIRE EARTH is 0.8 degrees.
I'll look at that web site (from where you provided the images) in more detail when I have a chance — at a first glance, though, where they assert «that the satellite data is inconclusive regarding any discernible trends in the global
yearly average temperature over the last 25 years», is a bit odd, given the > 95 % statistical confidence in warming
over that time period (as per @ 30).
If we are able to reduce the global
average yearly temperature to a single value, a value that is accurate to + / -.1 degree C,
over a period of 150 years and that indicates an increase of somewhat less than a degree C, what does that mean?
