Jerome Ravetz of Oxford University is a giant in the field of history and philosophy of science and is an environmental consultant. He has posted an extraordinary essay at Watts Up With That, meteorologist Anthony Watts' web site. While the essay takes a few minutes to read, I highly recommend it.
It is a shame that the U.S. media has self-censored the entire Climategate story. News consumers in other nations are far better informed at the collapse of the IPCC and its "consensus." Dr. Ravetz's essay will tell you what you need to know and put it in context.
