Daiwa-
Just ask Gallileo. It is the nature of scientific inquiry that nothing is accepted as absolute, that everything is open to question and doubt, that no question is ever settled.
I agree with you 100% on this. Never have I said anything contrary to it! However, the fact is that ever since the early to mid 90's there has been a consensus in the scientific community at large! That's thousands of scientists from different countries and institutes coming together in agreement. That's why, just recently, the national science organizations of ALL the G8 countries just released another statement confirming their position.
Using Galileo is a poor example- he was killed by the church for espousing beliefs that contradicted official doctrine. For the last 30 years, scientists trying to bring global warming to our attention have been the galileo's out there. After decades of research, however, there was so much information pointing towards man-caused climate change that all of these organizations started getting together and issuing joint statements so they couldn't be ignored. Is every scientist on the planet in agreement? Of course not, nor should they be. Just as an aside, if you happen to be a scientist who produces a paper that questions man-caused climate change you get instant publicity which can be a very good career move. But, for years scientific journals have had valid experiments published that had results supporting the theory of man caused climate change, with little or no coverage in the mass media. Why?
This is the same thing that the tobacco industry tried to do to disprove the link between smoking and cancer. If a study was published that indicated there's a causality between smoking and cancer, they had lobbyists and most importantly, scientists on payroll that would issue statements decrying those studies as 'junk science' or using faulty testing methods. "No discernible link can be found, more studies are needed!" was the word of the day. They then commissioned studies to prove that the link between smoking and cancer was nonexistent and called this 'sound science'. They kept this game up as long as possible, and again, cried that they were the victim.
There is a huge difference between observing the fact that there is a climate cycle and deciding you know not only all the factors influencing it but the relative contribution of each. Proposing remedies without knowing what their effects might be, taking definitive action on the basis of hypothesis alone, is not my idea of "scientific." I note that the APS boldly states "mitigation efforts must be taken immediately" without bothering to demonstrate the scientific basis for implementing "mitigation efforts" - the experiment simply hasn't been done, and can't be done, without risking all of humanity in the process. The hubris involved in such pronouncements is breathtaking.
No one has decided that they know all the factors influencing the climate. No one has decided that climate change is caused solely by man's activity. They have merely stated that they believe, with the information at hand, that there is a good chance we're contributing significantly to climate change. But this issue is bigger than 'global warming'. The root issue at hand here, is that for the first time in human history, governments and industry may have no choice but to acknowledge that man has the ability to affect our entire planet through his actions.
This is the root of the matter- because if that acknowledgement is made, the era of 'consequence free' development comes to an end. Let's talk about what that means. Consequence free development means that the planet is so big and powerful and resilient that we can do anything we want and it's not gonna make a lick of difference. A chemical plant spills benzene into a major river, no biggie! Just a regional slip up, no harm done in the big scheme of things. Coal mining companies deconstruct an entire mountain and contaminate the surrounding water tables, no worries! Mother nature is so great and powerful it won't have any effect on things. If there is anything we should have learned by now, it's that all actions however have consequences. Never before in the history of our world have there been 6 billion human beings walking it's surface, burning 85 million barrels of oil and tens of thousands of tonnes of coal and natural gas each and every day. To think that we can never affect our surroundings through our actions is the height of hubris, I would say.
Just as Galileo proved that we do not sit at the center of the universe, so too does this debate question our place in the bigger picture. Currently we live in a society that's built on the idea of exploiting our surroundings for profit and 'wealth creation'. This is necessary, for our civilization is built on interest. Everything must generate a return. Therefore we must constantly be developing, building widgets and gidgets and gadgets to sell and increase our profit. Food is no longer grown to feed people. It too, has become a commodity for profit. If we grew food to feed people, there would be no starvation on the planet as current food production in the world is more than enough to feed every single person. Same goes for pretty much everything else;
In the past, we grew food and constructed tools and buildings to provide a tangible necessity or function for ourselves and each other. Now, everything that's created is only a means to an end in generating wealth. Wealth, that is indeed artificial. You can't eat money, nor can you use it for much else, other than perhaps burning it as fuel in big bricks. Now, this works great so long as you have endless natural resources to develop AND the development of those resources has no appreciable effect on our environment.
Lo and behold, who could imagine that a century and a half of constant development, we might start to have an impact on our surroundings? The scientific community by and large believe that the data at hand indicate that, surprise surprise, we have had an effect and must deal with the consequences.
Once this admission is made, there is no more free ride, no more unchecked development and exploitation of our resources and environment in the name of profit. Since this would be very bad indeed for profits and the established order of things, of course there is a concerted campaign to discredit and sow misinformation and doubt.
Whod'a thunk it that actions have consequences!
