Evidence presented in the letter goes well beyond putting the “hockey stick” graph, made famous in Al Gore's movie, in doubt. The hockey stick presented exponentially increasing global temperature in the near future due to uncontrolled increases in CO2 – and got its name from the shape of the graph – an apparently long stable period with an upward increase in CO2 and temperature during the industrial age.

For a better description of the Hockey Stick, see What is the ‘Hockey Stick’ Debate About?

McIntyre and McKitrick have more recent stuff added to the debate, but that's still a pretty good place to start reading about it. More recent stuff at Climate Audit

Interesting presentation. There does appear to be a coincidental relationship between CO2 and temperature, just as “skeptics” have said. Thanks for adding to the database on hockey stick information.
