The Arctic's Tropical Past

140Mandak262Jamuna writes "The BBC reports on findings that the arctic/polar region was tropical some 55 Million years ago." From the article: "Although the data tells us how the world changed from one with green house conditions to one with ice house conditions millions of years ago, it may also help scientists to predict what will result from the present changes in climate. Appy Sluijs points out that the data reveals that some of the climate models used to detail the Arctic's history got things wrong, and as they are the same models that predict our future climate they may need adjusting. " The reader pointed out that this may have had as much to do with continental drift as it did climate change.

    If its the latter, then we still get the benefits of a cleaner environment. So why not take the steps?
    CO2 (and other greenhouse gases) are not particularly toxic. If we're only concerned about pollution, we should probably focus on things which are a bit more toxic e.g. mercury in the water which enters the human body through tuna, etc. And remember, there is no such thing as a free lunch. If you do impose heavy restrictions on companies in the "developed world," they'll simply move whatever tiny amount of manufacturing is still left to China or any other country which is business friendly and does not limit CO2 production of companies.

    I have a friend who has terrible motivation. Whenever he has a problem, it totally makes him freeze up... and it really hinders him in life. I tell him: "Well, why don't you try [solution X]?" To which he always responds, "Oh, if I do that, then all that will happen is [new speculated obstacle Y]."

    Sometimes I want to grab him and yell, "Maybe. Maybe not. But you could at least try!? Why talk yourself out of trying? If you try and fail, you're certainly no worse off than if you just sit around on your ass wishing the problem would disappear!!"

    .... and this is how I feel about many of the arguments against environmentalism. People poo-poo any specific action that is proposed, saying: "Oh, if you do that, then companies will just do this" or "If you do that, then you'll just see these other problems" or (my favorite) "If you do that, it might not make a difference." But why spend all this energy talking yourself OUT of even trying to solve a problem that needs (ultimately) to be solved, anyway?

    Sure, manufacturing companies might move oversees to China. But not all of them can afford to, and for some of them, they might calculate that the cost of moving overseas exceeds the cost of complying to environmental regulation. And in the end, more companies will still be more compliant, than if you just throw your hands up in the air and say "oh noes! nothing can be done-zo!"
