Having the 1975 NAS report in hand completely disarms alarmists. Thanks Dave!

It also provides a smoking gun that Mann had no legitimate reason to delete Briffa’s trees, which precisely matched the NAS graph.

Tree shrugger!
PS – Many thanks Dave.
Kevin Trenbeth’s new paper informs me that global warming never stopped. If one adjusts for ENSO, the warming still continues relentlessly. He then adds that the PDO switch has caused the deep oceans to absorb the extra heat, which is why we can’t measure it in the atmosphere any more.
Haha! He’s always good for a laugh, is Kev!
Indeed, we can’t even measure it in the *oceans*.
Steven & Dave,
Thanks for the link. Reading it now. My favorite passage thus far is page 36
“RECORD OF INSTRUMENTALLY OBSERVED CLIMATIC CHANGES
…Enough data have been
gathered, however, to permit the following summary.
A striking feature of the instrumental record is the behavior of temperature
worldwide. As shown by Mitchell (1970), the average surface
air temperature in the northern hemisphere increased from the 1880’s
until about 1940 and has been decreasing thereafter (see Figure A.6,
Appendix A). Starr and Oort (1973) have reported that, during the
period 1958-1963, the hemisphere’s (mass-weighted) mean temperature
decreased by about 0.6 °C.”
It has been incessantly drummed into our collective brains that the West Antarctic Ice Sheet (WAIS) could collapse at any moment.

See page 181 of the NAS report for a completely different take on the WAIS…
“the East Antarctic ice sheet has apparently varied
little since reaching its present size about 5 million years ago, while
the West Antarctic ice sheet appears to have been disintegrating for
many thousands of years.”
What the foo?
On Wikipedia Connolly refers to his own peer-reviewed paper which proves that what you are saying and linking to is just not true. There was no consensus about global cooling, check Wiki!
It is actually a good read. They approach the process with a fair amount of humility, noting problems with the instrumental records, the fact that almost all climate “trends” disappear on different timescales, and the stupidity of simply taking a trend (like the then-current cooling) and extending it indefinitely into the future. They expected about 0.6C rise by the end of the century from CO2, which would counteract the problematic cooling.
But they advise caution, note how much is not understood, and warn scientists about simply making statements without adequate knowledge of other disciplines. They have subsequently forgotten this humility.
