Gotta be careful not to mix everything together. Using technology and worrying or being fearful of the effects it can have on the environment is not the same as being worried about personas like Kim Jong Il. For one, we simply need the environment to survive, so being worried that pollution could actually endanger our own survival is sensible.
What the people in the middle ages lacked is knowledge, they believed the black plague in the 14th century was sent by god as a punishment and did not understand why it did not hit everybody equally. That lack of knowledge caused fear, which in turn made those look suspicious that did not get sick. Some sinners (in the context of mideaval society) stayed healthy and others that never sinned got sick and died. That inspired some to look for other reasons as to why the plague was spreading - modern medicine in Europe was born (or at least the scientific aproach to research sicknesses). The Rennaissance and its great minds like Leonardo Da Vinci are testament to that shift of mentality. I glossed over alot here, but the main gist is true enough.
Increasing our knowledge and using that knowledge and acting on it sensibly is the way to go, and fear is a great motivator, but it should not be the only reason why action is taken.
You stated what my point was THE NEED FOR MORE knowledge. I posted previously articles stating that global warming is not AGW and most likely there are multiple causes like the earth core heating up and the sun. My example stands true and you gave it even more validity with your very own statement. There is no need to rush to conclusions about a topic that only has come in the fore front in the last 10 to 15 years.
As for KJ II I think if he shot one or two nukes that the aftermath of this would have a greater consequence then the current facade of AGW. If Iran gets the Nuclear weapons I GUARANTEE that the surrounding countries will get them as well.
There are several fallacies that one could pull from this above quote
Appeal to consequences, which I stated in my previous post. If one is not enough then: appeal to force, post hoc. Need I say more?
Fear clouds our judgement
So make rational and cool-headed decisions, such as looking at how to reduce our activities that are harmful on the environment, as opposed to opposing any and all such changes because of the fear that they may be a waste of money.
To put it this way, you're offered the opportunity of buying a special ticket. There's a 50% chance that holding that ticket will be worthless, and a 50% chance it'll be worth $100. You can buy it for $30. Would you say yes? What if you could buy it for $80? Now assuming your risk aversion/fondness isn't massive, you'd say yes to the first one, and no to the second. It would be foolish to say no to buying the ticket regardless of the price though (the same as it would be to say yes regardless of the price). Similarly it is foolish to say no to any actions to reduce emissions/the effect of human activities on the environment, just as it would be to say yes to completely eliminating any such activities.
assuming the temperature rise is caused by humans. If it is not caused by humans, the trend could easily reverse
And current studies have determined it is highly likely that a significant amount of it is due to human activity - IIRC an IPCC had around half of the temperature increase thought to be due to human activity. There's still a chance it's not, but that shouldn't mean you ignore the issue.
You're statement again isn't logical. You're assuming that there is a chance so we need to act now! Its like that car salesman and his pressure sale I sale you it at 10000 you need to buy now buy now!
This would be like if I thought I discovered a cure for a new deadly highly contagious flu strain. Instead of putting it through any trial testing we should just administer it to as many people as possible and hope for the best. If it kills a bunch of people I had good intentions and there was no time to stop and test.
There is time to do research and figure out A BETTER PLAN and to narrow down what is AND isn't causing it. There is no need to make any hasty conclusions. One final example would be the fact that we know that there are plenty of huge astreroids that may come in the Earth's path. We can do all the mathematical formuals to show that some of these asteroids will come really really close to hitting earth. What we need to do is start building a missle defense system capable of blowing all those rocks before they hit. I am not saying we shouldn't have a plan but at least we now are looking and now that there are some rocks that are on a possible collision course for Earth BUT THERE IS NO NEED TO PANIC.
