Do Pirates Cause Global Warming?

There are a lot more than 17 pirates. In 2006, there were 239 pirate attacks, 188 people taken hostage by pirates.

And, joke's aside, it blows my mind that people thinks it's foolish to reduce emissions, whether for environmental or economic independence issues. Even if, by some long-shot, global warming and chemical emissions trends are coincidence there's lots of other reasons to reduce our reliance on fossil fuels.
Reduce emmisions? Can't I drive my Hummer to the grocery store in peace? Jeez.

Plus you have to expend energy to form hydrogen. The "energy expended to create/energy available from" ratio is nothing NEAR petroleum. I don't think there's much out there that can compete with fossil fuels when it comes to that.

So how are you going to create all this hydrogen? What kind of energy are you going to use?

Wind power can be useful on the small to medium scale. Just because an alternative source doesn't equal fossil fuel "efficiency" in terms of raw power doesn't mean we should write it off. Diversification, conservation and a change in habits would be most sensible.
We love our convenience. Like the DKs said "Give me convenience or give me death"
 
Politicians proclaim that hydrogen fuel cells are a solution to the global warming problem. What they seem to forget is that by Hydrogen combustion (or usage in fuel cells) the product is steam, which is also a GHG (greenhouse gas).


Politicians don't know Jack. Let engineers take over.

Steam is a greenhouse gas? Really? Then, guess what...

We're freakin' screwed!

Based on this new bit of information, I am now resolved to increase the size of my "carbon footprint" until I have truly earned the enmity of the enviromentalist nutbags and the world-renowned nickname "Bigfoot."

Screw it. We're only killing ourselves, anyway.

But, what about the children, you say?

Screw them, too!

By the time any of this happens, I'll be dead, along with a couple of generations of kids.

You know what the problem with kids is?

They don't stay kids. They grow up to be adults.

And, some of them grow up to environmentalist nutbags.

So, I say: Screw the children! They're just the whiny adults of tomorrow.

I look forward to the day the cockroaches take the planet back. They are sure to do a better job running it than we have.

People don't think it's foolish to reduce emissions. No one wants a dirty planet. The difference is in peoples' beliefs as to the proper balance between environmental concens and economic. Some think that economic concerns shouldn't matter; well, that's not realistic.
 
I know you're joking, but trees aren't going anywhere because they are a lucrative money crop. Clear cutting isn't how it's done anymore.

Besides, all that CO2 will be good for the trees, right?

You're right, but I'm only half joking.
The earth, being a living entity, changes in one area can drastically effect another.
Due to temp changes some of our forests here are being decimated by beetles. Until the temp increased they weren't a threat in these environments.

My thoughts exactly... I cannot fathom this whole hydrogen craze, I think it's just all hype. In any case, it is quite a difficult task to find a suitable replacement for oil when there is no more of that.
My diploma thesis was on the production of hydrogen from various industrial wastes, and as I researched more and more into this specific field, this whole hydrogen thing appeared to be quite stupid...
 
Anti-pastafarian I would think.

no, as a devout pastafarian I can explain this. Pirates are HIS chosen people, because the midgets didn't work out so he turned them into penguins. As the number of pirates dwindle, the HE is no longer as interested in earth, I mean, theres a beer volcano and a stripper factory where he lives. Because of that, he dosn't care as much if it gets a little hotter. Just be glad he hasn't forgotten to keep us all from floating away.

So that was the conclusion of your thesis?
Is there anything else useful in that waste?
 
In a word, no.
I concentrated mainly on using carbohydrate-rich materials, such as tofu wastewater or potato processing wastewaters. Methods used were either biochemical or thermal. Results were poor. I concentrated my efforts mainly on the design of photobioreactors, and got very very dissappointed...

For those of us disagreeing with environmentalists, let me just stress the importance of the finite nature of all resources. There is a book entitled LIMITS TO GROWTH which illustrates this rather vividly. The problem is not solely to protect the environment for our kids or their kids (frankly, I couldn't care less). From my corner of the ring, we need to pull lots of strings in order to be able to maintain our standard of living, should oil/coal etc fail to cover our needs. Hubbert's peak is near, or maybe even in the past, so now oil prices will start to escalate (not to mention the dynamic entry of the chinese in the market, and they are sucking up major quantities of oil at low prices, making oil more expensive for the rest of us), and maybe other forms or carriers of energy will become viable alternatives.

IN SHORT, what I'm saying is that I think that global warming is just the tip of the iceberg, if you excuse the pun. We are dealing with finite resources people, and we need to find a way out before it's too late...

edit: To answer lazylion's question more specifically, it would probably be best if such organic wastes be used in standard wastewater treating processes (oxidative ponds etc), and maybe burning the residue to produce heat. Conversion to hydrogen and from there to electricity is too many steps, and too many steps usually signify energy (maybe even mass) losses in all steps.
