Thal and Tassie, it's good to see well substantiated facts introduced to counter the arguments posed by some in this thread. Kudos to you. I must admit I have tired of fighting ignorance and it is time to go diving!

Oh! No! Dr. Bill!

Thanks, I've always believed that ignorance is a curable condition, but the problem is that stupid is for life.

Thanks to the mods for re-opening the post.

Firstly, that the world is warming is beyond doubt - this is confirmed not by computer models, or fancy math, but rather from millions of meteorological readings taken over the past 1.5 centuries or so. The fact that computer models, ice cores, tree rings, etc, all confirm this only lends weight to the conclusion.

Its also pretty clear that human activity is responsibly for at least part of the warming. But even if that conclusion is 100% wrong, its pretty much a moot point.

Think of it this way, if we take action there are two possibilities:
a) We are wrong, and it costs us $
b) We are right, and save modern society as we know it, and costs us $

In contrast, if we do nothing:
c) We are right, and we get of scott-free
d) We are wrong, and modern society as we know it falls

So doing something at worst costs money, and at best saves modern society. Doing nothing at best costs nothing, but at worst leads to the end of modern society.

Simply put, there is only one option which is morally correct - to do something. Because to do nothing risks everything - not exactly an ethical bet to be making with our kids and grandkids future.


And just one last comment, about absolute certainty. I've worked as a scientist for over a decade, and I can tell you that 100% certainty does not exist in science - the best you get is a high probability. Certainty can only exist once the event has come to pass - which is far, far to late to do anything about it.

There is a third possibility ...

c) We are right, and there ain't jack we can do that's going to significantly alter the course of events.

According to some accounts I've read, this is a plausible outcome ...

Fourth possibility. We're right, we take action, and the outcome is the opposite of the goal. We have, unbelievably, been wrong many times in the past.

There will always be extremist (both ways), moderates, concerned and the indifferent. They all have some validity in their opinion somewhere. I feel a solution will fall somewhere near the middle and will no doubt be a technological solution. Just think, if a new clean fuel energy source is discovered, the need for many carbon based fuels becomes a minor part of energy program. The oil producing nations fall out of the headlines. Time passes and the new clean fuel has produced a new side effect no one considered and the cycle begins anew.

I’m headed in the direction of recycling waste to energy. This way, both problems get solved.

Bio diesel becomes the fuel of the future and all the world will come after the bread basket of the US, Argentina, Australia, where it'll be produced...the new Saudi Arabias of energy supply.
But you're absolutely right. Many of the significant side effects of any big change are unforseeable.

I just read that biodiesel will have a big impact on the pH of ocean due to all the water contamination with fertilizer, crop run-off, etc (which is a bigger problem for reefs than even the temperature shift)

I got a brochure on this car in the mail the other day....they must have me mistaken for somebody. It is a very cool car, if H2 was just easier to produce. Nuclear production..maybe.

I keep seeing the goober on TV that has this car that runs on water that he made in his garage...anybody seen that guy? I think it is on U-tube too.

Frankly I see Bio-Diesel as an interim fix. It, being carbon based, it still pollutes albeit less than gasoline. I see car/trucks moving to a more organic fuel like alcohol or alcohol/electric hybrid. Besides, with existing technologies, cars and truck emissions are being reduced considerably.

The big energy users/consumers/polluters are power plants and ships. This is where a safe alternative fuel source needs to be focused.

A promising idea is plasma power plants. In addition, using small, safe nuclear reactors for commercial shipping would also go a long way in reducing emission and carbon consumption. The down side is what to do with the waste. This too is a potential new market. Imagine a company that has figured out a method to remove the radioactive activity of nuclear waste. The other big issue is how do you give/sell this technology to hostile governments?

But we will never know if we don't try. And when you think of the course of action that could make an impact, it isn't exactly challenging. For example, over the past few years I've made kinda-enviro sensitive decisions:

1) When my old car went to the giant scrap heap in the sky I bought a fuel-efficient car to replace it.

2) I've been replacing my incandescents with miniflouros, as the incadencet lights burn out

3) I'm moving at the end of October, and made a point of getting a place close to my work (no more f*&%%$#ing commutes, just a short bike ride away)

So my life is now cheaper and more convenient, and yet I've managed to cut my CO2 release by over 60%.

Obviously some of those are more difficult for most people (i.e. moving), but at the end of the day all three of those things save me money and time, and also cut CO2. Win-win for everyone.

If the problem is excess CO2, then reducing CO2 reduces the problem. We are now at the point where climate change is considered inevitable. All we're trying to do is limit the extent of the problem.

Take biofuels (to hijack another part of the thread). The carbon in those fuels comes from the CO2 in the air, so in a perfect world your net CO2 is zero. It doesn't work out this way, but at least for biodiesel you should end up releasing less CO2 then if you use regular diesel. Not a perfect solution, but it does have the effect of limiting CO2 release while we look for a better solution.
