RIGHT BEFORE IT WAS WRONG | Daily Telegraph Tim Blair Blog: "Professor Christopher Field, director of the Department of Global Ecology at the Carnegie Institution in California, who is the new co-chairman of the IPCC working group overseeing the climate impacts report, said the 2007 report had been broadly accurate at the time it was written.
He said: “The 2007 study should be seen as “a snapshot of what was known then. Science is progressive. If something turns out to be wrong we can fix it next time around.”"
So everything is right, until it is wrong. Then the new thing is right until it is wrong. And don't you dare argue about what is right, because it's right. Until it's wrong.
