Dear AllStat,
Professor Zhigljavsky raises some valid concerns - though I suspect he's
fallen into the same error as everyone else of analysing inferior data.
The problem is inferior to what and how do we access sufficient data? Are
the ice cores from the arctic or Antarctic not pretty definitive?
Then, in such a complex model; there are bound to be many ways to analyse it
(under different assumptions); we need the results to be consistent to build
confidence.
Is there anyone on the list who feels able to comment on the statistical
analyses used in the climate debate?
As for the East Anglia debacle, where (depending on how you discuss it)
scientists hid data, changed data or questioned its usefulness. I'll never
describe transforming my data as "a trick" again!
Regards
John

Dear Allstat,
Global warming is a phenomenon which is forecast over a long period of time
and as such more data is needed to be able to justify this conclusion, I
guess data over different sub-regions/continents for a period spanning not
less than 100 years is needed.

Dear allstat fellows,
I though some of you might be interested in what I have done after I got
tired of listening about Global Warming and ClimatGate.
I decided to check the data myself. The result is the following website:
http://www.cf.ac.uk/maths/subsites/zhigljavskyaa/climatechange/
I did not find any signs of the Global Warming!
Sorry, the statistical part in my short report is poor (this report is not
for professional statisticians!)
Any comments?
