If global cooling was just a few researchers it wouldn't have received the cover story that I quoted in Newsweek.

</font>[/quote]Now we are just confusing ourselves. [img]smile.gif[/img] I was referring to people talking about global cooling in the 1970s that Nakona mentioned. What you are referring to is the possible phenomenon of melting ice-caps causing the gulf-stream to change, making North America and parts of Europe colder. That is interesting speculation and an area for further research, but note as someone else said, its _local_ cooling because of global warming, not global cooling.
|As far as global warming being the consensus of the entire scientific community, this is just not the case. There is lots of discussion going on....Even amoung those that believe it to be the case there is significant disagreement about just how much mankind has to do with it and just how much other factors (such as million year warm/cool cycles, and sunspots) has to do with it.
Arghh..not true! You might have been able to say this five or ten years ago, but not now. Yes, it is true there are many factors that affect the climate, but there is no quesiton that a significant and sudden factor is human activity. I encourage you to look at unbiased sources, for example in Scientific American or the National Academy of Sciences, or how about even biased sources, like the Bush White House, who would like to sweep this under the rug if at all possible? Here's what GW had to say:
|There is a natural greenhouse effect that contributes to warming. Greenhouse gases trap heat, and thus warm the earth because they prevent a significant proportion of infrared radiation from escaping into space. Concentration of greenhouse gases, especially CO2, have increased substantially since the beginning of the industrial revolution. And the National Academy of Sciences indicate that the increase is due in large part to human activity.
Ok, that's George Bush, not someone who really cares about the environment, right...but he does recognize that it would be completly silly at this point to pretend that global warming isn't occuring.
Notice that Global Warming is now reported as a fact, not speculation, and it is also a fact that it is caused by human activity.
I agree with you by the way that the environmental movement has in many cases done more harm than good by cultivating a doomsday mythology, creating an us-vs.-them attitude, and failing to recognize progress that has been made. But just because chicken-little is running around with his head cut off does not mean that the sky is not falling and we can all just relax.
Its disheartening to read what people have to say about this because they either seem to think a) "no one really knows", which isn't true, or b) "we're all doomed and there is nothing we can do about it, so let's enjoy ourselves while we can."
Its actually the second response I'm most worried about, and again, the environmental movement can share some of the blame here. Beyond that, people in this country have really gotten the idea that they can't do anything to change anything, but you can, and its our responsibility to do so, even if it means just finding out a bit more about it and sharing what you learn with others.
btw, I know some poeple might feel that this discussion seems OT and political, but I can think of no issue more important to skiers, so I think it belogns here.
