Why Aren’t Global Surface Temperature Data Produced in Absolute Form?

The title question often appears during discussions of global surface temperatures.   That is, GISS, Hadley Centre and NCDC only present their global land+ocean surface temperatures products as anomalies.  The questions is: why don’t they produce the global surface temperature products … Continue reading
