Thought I'd actually go to the source and evaluate this article's claims.
As you can see in the
United Nations' International Panel on Climate Change report, Mann's study was used and relied on, but it was far from the only source of data:
"Taking into account these substantial uncertainties, Mann et al. (1999) concluded that the 1990s were likely to have been the warmest decade, and 1998 the warmest year, of the past millennium for at least the Northern Hemisphere. Jones et al. (1998) came to a similar conclusion from largely independent data and an entirely independent methodology. Crowley and Lowery (2000) reached the similar conclusion that medieval temperatures were no warmer than mid-20th century temperatures. Borehole data (Pollack et al., 1998) independently support this conclusion for the past 500 years..."
From that I'd say that the questions about Mann's work don't blow up the support for climate change the way the article implies.
