People who believe that the Earth's surface temperature has been rising according to NASA/GISS (Al Gore and James Hansen)need to read this article, which shows the problem with the record, and the way the data are manipulated:

There are four organizations that monitor the Earth's surface temperature:

NASA/GISS

NCDC/NOAA

HAD/CRU

RSS/MSU

Of these only the NASA Goddard (NASA/GISS) record shows that temperature is still increasing. THe data used by the anthropogenic global warming advocates is clearly bogus. It is impossible to tell what is happening with such compromised data. It is hard to believe that this is simply a matter of "confirmation bias."
