Global warming - what does the NASA/GISS satellite record show?

The "slow increase (planetary cooling*) of global upwelling LW flux at TOA from the 1980's to the 1990's, which is found mostly in lower latitudes, is confirmed by the ERBS records." and:
"The overall slow decrease (planetary warming*) of upwelling SW flux from the mid-1980's until the end of the 1990's and subsequent increase from 2000 onwards appear to be caused, primarily, by changes in global cloud cover (although there is a small increase of cloud optical thickness after 2000) and is confirmed by the ERBS measurements."
