Re: [Phys-L] Global Warming (Was: just for fun?)

[Richard Tarara <rtarara@saintmarys.edu>]

After a very quick look--this ONE paper deals with only the latter 
portion of the historical data and does so primarily by reworking the 
global temperatures.  Some comments from other sites caution that at 
least one of these authors was involved with the 'hockey stick' graph 
that has been withdrawn by the IPCC since that reworked the temperature 
data and made the 'little ice age' and medieval warm periods apparently 
go away. Too early to tell if this work really changes anything but I'm 
certainly not qualified to make that judgement.
