I don't think 60 minutes is qualified to make a scientific assertion like that. Firstly, they represent one network that makes it's money from selling ratings (and their funders are only interested in ratings to sell products). And two, they represent one country, the USA, who's politicians already hold a confusing stance on global warming. The politicians are tied into the media and oil companies.jimmie said:Oh yeah, the report also said the debate is over as to whether or not global warming is anthropogenic; it is.
Also, just because a paper or two gets published in a scientific journal, doesn't always mean it's an accurate portrait of all the events and their dependencies.
From my laymen point of view, I think the 'hockey stick' authors are just as questionable as Mann (who's journal article supported the anthropological connection). They made a rebuttle to Mann's statistics, but without understanding the complexity of the math, myself, I have to be suspicious of the authors of the hockey stick article because the primary author is tied to oil companies, and the secondary author is tied to economics. I always hear economic majors practicing arguing about global warming, claiming that reduction of fossil fuel levels is uneconomically realistic, which isn't really the argument at hand, but it implies to me that both oil companies and economists are threatened if the antrhopological connection is true.
I don't think anybody can really judge yet. We're talking about international collaboration of a crapload of data in different languages, with possible errors all over. Now that it's such a big deal (and since the politicians are pushing their sides of the issue so much) I'm seeing so much disagreement that I don't think anyone really knows what's really going on.
They just have a lot of data and assumptions, so they can (each of them) pick at the data and connect it to their assumptions. I think we need mroe time for this one.
