I know that people like to argue about climate change here. I just saw this link on another site, and I think it might be a good place to go surf around and learn something.

http://climate.nasa.gov/

Happy reading.

A little late to the party, are we?

To the denial crowd, scientists and NASA are the center of this "conspiracy."

Climate Change: Uncertainties

Quote:
climate scientists do not have much confidence that they understand longer-term solar changes.
Quote:
So aerosol forcing is another substantial uncertainty in predictions of future climate.
Quote:
Current climate models do not represent cloud physics well,
Quote:
It isn't well understood where this carbon dioxide goes, with some evidence that the oceans are the major repository and other evidence that land biota absorbs the majority.
Quote:
Global ocean data sets only extend back to the early 1990s, so there are large uncertainties in predictions of future ocean changes.
Quote:
For just one example, some models forecast less precipitation in the American southwest, where JPL is, while others foresee more precipitation.
Quote:
The panel concluded that it could not "provide a best estimate or an upper bound for sea level rise" over the next century due to their lack of knowledge about Earth's ice.2

Actually one the major people involved with the AGW crowd is Hansen of NASA who once compared coal trains to Nazi death trains and has been arrested more than once at environmental protests. He's an embarrassment to to the scientific community at NASA.

NASA

James Hansen, head of NASA’s Goddard Institute for Space Studies, was arrested outside the White House as he joined protesters in urging President Barack Obama to reject TransCanada Corp. (TRP)’s $7 billion pipeline.

Before he was taken into custody today, Hansen took a megaphone and implored Obama to act “for the sake of your children and grandchildren.”

“If Obama chooses the dirty needle it will confirm that the president was just green-washing all along,” Hansen, 70, who took a vacation day from his job at the New York based institute to participate in the protest, said in an e-mailed statement.

I think the problem starts when the uncertainty is not considered as part of the whole.

I don't think there's a climate scientist out there that will deny those uncertainties. I teach about climate change in my classes and I address most of those (some that you mentioned have more to do with weather than climate). I also address the most uncertain uncertainty of all: human behavior.

You bring up an interesting standard. Sure, I agree that sometimes the pundits act like we have it all figured out on climate change,etc. Of course we do not, at least completely. However, we have enough understanding of atmospheric chemistry to make some very accurate predictions over the long haul, even if precision or complicating factors are not all fully understood.

The difficulty right now is how we as a society deal with this uncertainty. Do we deny the general predictions entirely? Do we blindly trust the scientists? Neither seems ideal. Unfortunately, the political environment has become so polarized and nasty that folks feel they must defend their point of view, and uncertainty is evidence they are right and the other guy is wrong.

Do we though? For example in the early nineties hurricane models weren't accurate, over two decades they collected copious amounts of very accurate data and were able to test their models again and again angainst known results they improved over time and they have some fairly accurate models. improve them Of course greater computing power has also played a factor too.

The complexities of climate are far greater, the accuracy of the data is subject to speculation and the there isn't a known result.
