The idea that the MSU record somehow provides more accurate or
reliable temperature trends
than surface measurements with thermometers, sometimes promoted by «climate skeptics», is scientifically untenable.
But the IPCC said the longer term trends were clear: «Each of the last three decades has been successively warmer at the Earth's
surface than any preceding decade since 1850 in the northern hemisphere [the earliest date for
reliable temperature records for the whole hemisphere].»
Many researchers seem to have assumed that the weather station - based estimates are much more
reliable and consistent
than the Sea
Surface Temperature estimates.
Sea
surface temperature has been consistently higher during the past three decades
than at any other time since
reliable observations began in 1880.
If this is the best such land area
surface temperature assessment system on the planet (covering, as well, a broad range of metropolitan, suburban, and rural areas), and the quality of the system is now proven to be demonstrably more prone to error
than had been previously assumed — with the preponderance of error shown to produce the impression of warming in excess of real conditions prevailing — what may be reliably inferred about
surface temperature monitoring systems data from even less
reliable thermometers all over the rest of the world?
A similar, but stronger case can be made using
surface temperature datasets, which I consider to be more
reliable than satellite datasets (they certainly agree with each other better
than the various satellite datasets do!).
