More disinformation. I'm surprised the Times published this article. The 
paragraph

�The story is the same for each one,� he said. �The popular data sets show
a lot
of warming but the apparent temperature rise was actually caused by local
factors affecting the weather stations, such as land development.�



is typical, and the SI article, in the rebuttal of the statement that 
global warming is spurious and due to the fact that temperatures are 
taken in cities, refutes it. The paragraph

�It�s not just temperature rises that tell us the world is warming,� he
said.
�We also have physical changes like the fact that sea levels have risen
around
five inches since 1972, the Arctic icecap has declined by 40% and snow
cover in
the northern hemisphere has declined.�



restores some sanity to the article. Even the most rigid climate deniers 
admit that global warming is real. They just deny it's anthropogenic. 
The authenticity of these results is suspect. They do nor appear in 
peer-reviewed pubications and the statement that they "are to be 
published" does not assuage my skepticism. The denialism of this article 
is of the most primitive kind, and reminds me of the stance of the 
tobacco companies about cancer in the 1960's.
