"Scientists Dispute Climate Sceptic's Claim That US Weather Data Is Useless"

"It appeared to have shaken the credibility of one of the most important global warming data sets in the world. A blog-inspired campaign by amateur climate sceptics seemed to show that numerous weather stations across the US were so poorly located they could not be relied upon.

But a new scientific analysis, using data from the sceptics, has shown that, if anything, the poorly located stations underestimate warming, rather than exaggerating it."
