Pick a Date, Any Date - GW Still?

"Or, you can pick a different start date to your liking.  How about 1998?  That will give you an entire 20 year run.  It's hard to say that the verb "is" should cover a period of more than 20 years.  On the UAH series you can see that temperatures have also fallen about 0.4 deg C since early 1998.  Again, even on this substantially longer scale, the earth "is cooling."  (Note, however, that there is a significant difference between the Wikipedia chart and the UAH satellite series as to what has happened since 1998.  On the Wikipedia chart the latest reading (2017?) is up about 0.3 deg C from 1998; while on the UAH series, the latest reading (July 2018) is down about 0.4 deg C from the then-records set in 1998.  That's those "adjustments" in the surface temperature record that I was talking about.  I would say that there is no credible position that the heavily adjusted surface temperature record that Wikipedia relies on should be used for this purpose over the far more accurate and un-tampered UAH satellite record.)"

As a friend said, if you own the data set, you own everything. If you can "adjust" the temps due to your calculations for known distortions, you win.
