My apologies if this issue has already been raised. I'd love to hear everyone's thoughts on it, though, if it hasn't.
Nobody is saying that climate changes aren't going to happen whether or not we take better care of the Earth. However, I think that there is no question about the fact that we speed up the changes doing what we're doing today.
Air pollutions prevent heat from rising from the ground while at the same time the use of various gases and other substances damage the ozone layer, allowing more sunshine to shine in which increases the temperature further. As I said in my initial post here, 2005 was the warmest year in many places over the world since they started the measuring of temperature - the ten highest measurments are from the 1990s or the 2000s. And even though I'm a firm believer in the power of evolution, there is no way all the different spieces of animals and plants can adapt this fast to the climate changes. I don't know for sure, but I bet climate researchers can see changes coming gradually and long before they actually occur. The Earth follows patterns and cycles just like all other organisms, I'm sure, but when the changes from decade to decade and sometimes even from year to year are so prominent, and when we at the same time know for a fact what effects certain substances have on nature in general, it isn't that hard to conclude what the effects are in a macro perspective. Then add the effects that pollutions have on the oceans, causing plants to grow faster and using up so much oxygen that the fish suffocate. I do believe this also causes the temperature to rise in the water, speeding up the green house effect even more. As we all know, cities by the sea are always warmer than cities inwards country because the sea helps to heat up the land.
Also, a while back Django said something about people exaggerating the severity of their claims. I believe Gol responded with something akin to "why would they do that?" Again, it's possible this has already been addressed, but if not, I'd like to point out that it's always in someone's interest to exaggerate a threat; especially politicians. The more threats there are, the more we need them to deal with them. Politicians hype problems for the same reason civil rights "leaders" hype racial tension; without it, they have less reason for existing.
Hype? You mean as in hyping the threat of WMD:s?
If there is something that upsets you, that you think is unfair or wrong, you might want to do something to change that fact - so you start working politically to change that. How is that "hype"? I actually think that is a very lame argument for why environmentalists would be just that: environmentalists or "greens". It's like saying that Conservatives like low taxes, not because they think it's good for the economy or for the individual, but because they would not exist without people being afraid of high taxes. A circular reasoning that really leads nowhere.
The difference between those who advocate tougher methods against air and water polluters and those who say that "it's not that bad - in fact, it's not bad at all" is that the greens do it for ideological reasons while the Oil Industry et al are doing what they're doing because of one thing only: money. The greens are allready underdogs: they haven't got the majority vote behind them, many consider them to be uncomfortable hippies, they don't have any particular political power and they certainly don't have any financial power. And they get very little coverage in media, despite what some are claiming here. It's not like they have anything to win by making all these things up. The green parties all over the world are built up by people who have a greater knowledge than the average man about at least one thing - the nature. You don't join a green party if you want to make a political career - then you join one of the major political parties.
At the same time, the Oil Industry, and the corporate world in general, attracts people who want to earn a buck and gladly more than one. If you, as an oil company executive are faced with two options: make the greens happy and lose some of the shareholders' money OR keep doing what you're doing and make the money grow. What do you do? You're obligated to think about your company and its shareholders first and the environment second - it's as simple as that. But you can't look as the bad guy in the eyes of the public, so you find methods to make the decay of the nature as a myth and to remind people how devastating these "green changes" would be to their daily comfort.
My point is, those who try to tone down the "man-made threats" against the environment have billions of reasons for doing so while the defenders of the environment have no other hidden reasons than saving the environment for doing what they are doing. The methods the environmentalists are sometimes using or the fact that they tend to forget other issues than the environment is another discussion. But their intentions are not only good but right.
