I just found a GISS web page with a temperature graph. Oddly, the
graph starts at 1880, which is close to the coldest point in the 19th
century; go back another sixty years and you'd see little warming at
all. There's another interesting web page at:
http://www.vision.net.au/~daly/low-head.htm
Which covers an Australian station used in CRU studies, showing that
the supposed 1C temperature increase there over the last few decades
was due not to global warming, but to trees growing nearby and blocking
out a cold wind. How many more such dubious measurements have been
included in the global warming computer-aided guesses?
