Freeman Dyson on Global Warming

From Town
Saying that on a recent trip he and his wife found Greenlanders to be delighted with their warmer climate and increased tourism, Mr. Dyson suggested that representing “local warming by a global average is misleading.” In his comments at both the Nassau Club and Labyrinth, he decried the use of computer modeling to make “tremendously dogmatic” predictions about worldwide trends, without acknowledging the “messy, muddy real world” and the non-climatic effects of increased carbon dioxide. “There is no substitute for widely-conducted field operations over a long time,” he told the Nassau Club audience, citing the “enormous gaps in knowledge and sparseness of observation” that characterize the work of global warming experts.

For those who may not know who Freeman Dyson is, he's a renowned physicist, known for questioning prevalent theories (which used to be the role of all scientists). A quick summary of his resume:
Mr. Dyson’s credentials are venerable: the British-born scholar received a BA from the University of Cambridge in 1945, and was, from 1953 until his retirement in 1994, a physics professor at the Institute for Advanced Study. The absence of a PhD in his resume has been more than compensated for by the 21 honorary degrees he has received over the years.
The Institute for Advanced Study is where Einstein worked.
