"There had been a warming trend since '69 I lived through that period so I know better. "

Well, that certainly proves nothing. Did you learn better arithmetic in that period? I've inserteded the years so you can see for yourself.

( 1989)
Yet in the U.S. there has been little temperature change in the past 50 years (from 1939-1989) , the time of rapidly increasing greenhouse gases — in fact, there was a slight cooling throughout much of the country (Figure 2). We caution that linear trends, as in Figure 2, can mask temporal detail. Indeed, Figure 1(b) indicates that the last 20 years (1969-1989) have seen a slight warming in the U.S. Nevertheless, our analysis (Hansen et al., 1999a), summarized in Figures 1 and 2, makes clear that climate trends have been fundamentally different in the U.S. than in the world as a whole.
