See, *there* is the issue. It's true that Slashdot has changed...but so have many of its users.
It USED to be that people could have a discussion about things, like whether or not global warming is actually happening. Some posters have provided some excellent links to studies that simply can't be refuted, and yet I see posts that say things like "...There is no doubt what has happened..."
I hate to break it to you, but YES THERE IS DOUBT. IAs a scientist having given the data some study, I can tell you it is my evaluation that most of the studies don't pass basic methodology on data collection much less on the conclusions they draw. And the computer simulations that back up most of these studies? Oh my goodness...these people would flunk a simulations class I taught, their code is that bad. To watch armchair scientists scream and yell that there's "consensus" when that is meaningless in the scientific realm is both amusing and grating.
On a technology site one discusses and debates, one does not proclaim "there is no doubt". With science there is always doubt. There are theories which fit the data better than others, but as soon as they fail (such as, say, AGW predictions of an ice free Arctic) there's a need to revisit and, if necessary, discard.
Anti-science is refusing to discuss and debate.
