If that is so then a hefty portion of the scientific community is also making this "assumption". I would like to believe that scientists are sincere people doing work they consider valid and necessary and not merely political puppets. Some, maybe but most? I hope not.
That's precisely my point. Many qualified scientists decry the Gore model of global warming because they believe the evidence shows that Gore's followers
are making assumptions without evidence.
Perhaps because our current science doesn't have the capacity to monitor the scale of those fluctuations, nor their rate.
Then how does one know global warming is happening at all? If we don't have faith in measurements of global temperature taken 30, 50 or 100 years ago, on what basis can proponents of human-caused global warming say that the Earth is heating up?
The earth is not a static object, it constantly changes over time. Why then would climate data from the cretacious period be considerd relevant to the modern earth? Additionally, there has never been any previous industralized society upon which to base any assumptions. We're our own guinea pig.
The Earth is the Earth is the Earth. What is on it has changed, but the structure and essential chemistry of the planet has been pretty consistent since the Antedeluvian period. There is no difference chemically between CO2 emissions from active volcanoes and CO2 emissions from a coal plant. The question is whether all the industrialization in the world can be the sole cause of the planet's mean temperature to climb half a degree.
As I said, the earth's ecosystem is able to cope with these events as they are part of that system. The emissions do not "go away" either, the settle into the enviroment in the form of mist, dust and heat. As we continue to add in pollutants of our own making that would not otherwise be there we gradually offset that balance. Perhaps by as much only as 0.0000001% but that's still not zero. And unlike say a volcano or meteorite, our contribution is consistant and continuous.
Well, such a figure would be statistically insignificant, and not account for the 0.5 degree rise in global mean temperatures over the last 30 years. And massively handicapping the leading industrial nations of the world - the nations most responsible for wealth creation, political stability and technological innovation - seems a lot like using a sledgehammer to swat flies - unproven, possibly imaginary flies, at that.
Logic would point to solar activity. All the same, this doesn't preclude the possibility of a human factor in global warming, on the contrary it only aggrivates it further. Naturally we can't do anything about the sun but we can do plenty about us...
But you have to prove that the human factor
is a significant factor. You also have to prove that the cure isn't worse than the disease.
No, I'm assuming the glass has a certain amount of pee in it naturally. Our pee is being added in on top of that and the brita filter is gradually approaching toxicity...
If those societies are as advanced and competitive as we are led to believe then this shouldn't be an issue. I have faith in very few things in life but one I thing I know I can count on is human greed. As soon as someone figures out how to get rich off this scenario, the paradigm will shift in a heartbeat. In fact, this is the very reasoning why many believe there's an outright conspiracy to prevent such advances from occuring (not me though, I think the powers that be are just greedy and lazy and simply aren't willing to put in the effort).
I worry very much about the real motivations behind Gore's climate control model. I see very little difference between his proposed cure and outright income redistribution. What communism and socialism could not accomplish, the rabid environmental lobby might.
Science is rule by consensus until someone breaks the consensus. Earth flat---> Earth round, Speed barrier unbreakable---> Speed barrier routinely broken, Global warming caused by....? Wait and see. Trouble is, California may have to become an island chain before we know for sure.
Science is not ruled by consensus. It's ruled by evidence. If there are 100 people in a room, 99 of whom believe checkered bunny rabbits are naturally produced, yet provide no evidence for their claims, and one in the room who provides evidence to the contrary, the one is acting scientifically, and the 99 aren't. That's why Galileo suffered as he did.
I'll tell you one thing I have noticed though, there's been a distinct change in the counter arguments over the past 10 years:
Early 90s- Global warming's a myth!
Mid 90s- Global warming's a mistake, we're actually cooling!
late 90s- Global warming's an exaggeration! It's perfectly natural!
Today- Global warming is... real... but it's not our fault! Honest, it was like that when we got here!
This is another straw man argument, CapnG, because the vast majority of scientists who don't believe in human-caused global warming have been asking for one simple thing:
evidence. Show
conclusive evidence that the planet's slight warming trend over the last 30 years is caused by man, is likely to continue, and can be solved by a change in man's behavior.
They have consistenly presented
evidence -
hard evidence - to the contrary. There is no question that the Earth has had warming and cooling cycles that correspond remarkably to increased solar activity, and that these cycles have occurred in periods in which mankind was not industrialized, or even in existence. They have provided evidence that other planets - planets where there is no industrialized human presence - are warming in a way that matches the relative rate of warming here on Earth. This evidence debases the very premise of the Al Gore crowd. Those folks cannot choose rhetoric over evidence without being unscientific bombasts.
Humour me for a moment: Say global warming is man made (or at the very least, accelerated by man's industry). So we, as a species, put forth the effort to research and employ alternate means of power generation and manufacturing. Reduce pollution levels to almost nothing. Reclaim and recycle as much waste as possible to bring that down to almost nothing. Conserve, manage and refine use of existing resources. We struggle, we suffer but ultimately we make it, we get the utopia we've all dreamed of where high-tech humans can live and work within nature without having to become granola eating neo-hippies.
Then we make a startling discovery: Global warming wasn't our fault after all. Holy crap! We could have all been driving hummers for the next 3000 years and it wouldn't put a pimple on good ol' mother earth! Except of course we'd be living in a cleaner, more efficient, better world.
Remind me; why is this a bad thing?
I'm not sure that what you're talking about is a utopia. but I'll go along. Any "suffering" that places a nation's competitive economy (and thus their national security) at risk is unwarranted if there is not a single reason to undertake it.
I have no objection at all to folks looking for alternate sources of energy. I strongly believe that getting off of oil would revolutionize U.S. foreign policy and allow the world to shuffle off the Middle East for good. I'm all in favor of that. But I do not believe that shelving oil dependency should be done to correct a problem I have no evidence exists, and I don't believe drastic, crippling handicaps should be placed on Western economies to fix it.
I think an alternate-fuels guy's best argument is the national security one. If you were arguing for alternate fuels on that basis, I'd buy you a drink and shake your hand. There's no question that the circumstances of oil production lends otherwise insignificant nations power and influence beyond all rationale. I don't think a real argument can be made for human-caused global warming because the evidence just isn't there and the cure is worse than the disease.
