Roy Spencer On Satellite v Surface DataPosted: January 20, 2017
“So, why are the surface thermometer data used to the exclusion of our best technology — [NASA] satellites — when tracking global temperatures? Because they better support the narrative of a dangerously warming planet.”
By Paul Homewood
With the continuing divergence of surface and satellite temperature records, it is worth revisiting what Roy Spencer had to say on the issue in 2014:
Much is being made of the “global” surface thermometer data, which three-quarters the way through 2014 is now suggesting the global average this year will be the warmest in the modern instrumental record.
I claim 2014 won’t be the warmest global-average year on record.
..if for no other reason than this: thermometers cannot measure global averages — only satellites can. The satellite instruments measure nearly every cubic kilometer – hell, every cubic inch — of the lower atmosphere on a daily basis. You can travel hundreds if not thousands of kilometers without finding a thermometer nearby.
(And even if 2014 or 2015 turns out to be the warmest, this is not a cause for concern…more about that later).
