It's very easy to form an opinion based on the assertions of people who profess to be experts, but it's shocking how strongly-held and vehemently-defended such opinions can be.Evo said:True, we have that issue in the Earth forum right now. We have no climate scientists in there, but some seem to profess that they have greater knowledge than others that have the same level of non-expertise that they have. Maybe they've googled more, who knows?
Let's acknowledge that no matter how much access any individual can have to publicly-held records, climate is extremely complex. To process the mountain of data, you need to get it into a form that is compatible with data from all the other sources that you use. Then you have to construct models that can run simulations with all that data to see how closely the models conform to observations, and try to decide if predictions can be made. Anybody here have a super-computer at home to run such simulations? I didn't think so.
If Randi wants to dig a bit more and keep wearing his professional "skeptic" hat, I'm all for that, because I'm in exactly the same boat. It's not a position that is popular with AGW believers OR AGW deniers, but it's a reasonable position for a thinking person to adopt. If Randi's decision to revise an earlier position and revisit the subject should have any camp cheering, it's the skeptics, not the pro or anti AGW crowds. The stakes are very high either way.
Ancillary benefits for making large polluters clean up their acts should not be overlooked. Thanks to large mid-western coal-fired power plants, the mid-west gets cheap electricity and Maine gets acidified lakes, almost-constant ozone alerts in the summer, mercury bio-accumulating in our fish, and other heavy metals like cadmium bio-accumulating in wild ruminants. Maine is paying a very heavy price for the mid-west to get cheap electricity. China practically shut down heavy industry upwind of their Olympics so that the world wouldn't see what ecological damage they are wreaking on their own country and the world. Cleaner industry comes at a cost, but inaction may come with a much greater cost.
IMO, the benefits of a cleaner environment should be factored into any decision to limit carbon emissions, regardless of whether or not we can prove that human activity is warming the Earth. Separating these issues works to the benefit of industries, but threatens the populace.
