James Hansen told Congress in June 1988 that it was going to be the hottest year ever. But by December he had backed down because a La Nina caused temperatures to plummet, which he called “unusual Pacific Ocean currents.”

Hansen said at the time that earth had warmed half a degree over the past 100 years. NASA now shows almost double that much warming from 1888 to 1988. They constantly increase historical warming, because they think no one will notice.
NASA has already announced that 2016 is the hottest year ever, and once again we appear to have another La Nina setting in.
However, this time around I wouldn’t bet against NASA making 2016 the hottest year ever, because they no longer make any pretense about trying to be honest and have already jacked 2016 up 0.75C.
amazing really considering- “At the same time,
Meteorological Services have difficulty in making urban observations that are not severely compromised”
WMO – “There is a growing need for meteorological observations conducted in urban areas. Urban populations continue to
expand, and Meteorological Services are increasingly required to supply meteorological data in support of detailed
forecasts for citizens, building and urban design, energy conservation, transportation and communications, air
quality and health, storm water and wind engineering, and insurance and emergency measures. At the same time,
Meteorological Services have difficulty in making urban observations that are not severely compromised. This is
because most developed sites make it impossible to conform to the standard guidelines for site selection and
instrument exposure given in Part I of this Guide owing to obstruction of air-flow and radiation exchange by
buildings and trees, unnatural surface cover and waste heat and water vapour from human activities”
and what is going on here-
WMO – “Surface temperature
Surface temperature is not commonly measured at urban stations, but it can be a very useful variable to use as
input in models to calculate fluxes. A representative surface temperature requires the averaging of an adequate
sample of the many surfaces, vertical as well as horizontal, that make up an urban area. This is possible only
using infrared remote sensing either from a scanner mounted on an aircraft or satellite, or a downwardfacing
pyrgeometer, or one or more radiation thermometers of which the combined field of view covers a representative
sample of the urban district”
Tony, you may want to consider scrapping the SSTa maps from Unisys and using the ones from CMC Environment Canada:
