Satellites all over the world and they still don't know with certainty which direction the hurricane will move in the next 24 hours. Give me a fucking break. Next you're going to convince me that a doctorate in philosophy has practical use in the world.

          As far as I am concerned this whole "global warming" concept is about two things. Job creation for climatologists following this business model 1. Create awareness of a problem 2. Pretend to be able to solve said problem. Since climate change happens over GEOLOGICAL TIME, well the "problem" is only going to get worse, isn't it? This means permanent funding for governments willing to pay anyone who gives them an excuse to REGULATE and TAX people even more.

Since he's won a pulitzer and I've enjoyed his previous works, I started reading - up until the point 1/3 of the way through when he tries to explain global warming with Carbon dating. The only problem is that the man has NO FUCKING CLUE as to how carbon dating actually works.

    "This extra CO2 is not coming from the oceans. It's coming from the burning of fossil fuels. We know this because carbon can be dated, and the carbon dioxide that is produced from burning fossil fuels is of a different age than the CO2 contained in the oceans. And the measurements definitively show that the carbon dioxide increase in the atmosphere in the last fifty years is coming from fossil fuel combustion" - PAGE 119

    Bzzzt - disqualified. Carbon dating absolutely does NOT work that way. A CO2 molecule's age can ABSOLUTELY NOT be determined. The "age" of CO2 in the atmosphere can ABSOLUTELY NOT be determined.

    Solar has a SERIOUS problem that makes it completely resistant to corporate investment... It's that it is virtually impossible to monopolize the market.

          I don't understand. Money can be made without monopolies. How many clothing stores are in your shopping mall? How many restaurants sell hamburgers and fries? Or Chinese food. Or fried chicken. Take your pick. The patents on acetaminophen/paracetamol expired a long, long time ago. Yet how many different companies sell this type of pain reliever? I don't buy your argument. You CAN make money without monopolies you know.

          I think the problem with solar is still one of price and efficiency, not monopoly. We have gotten used to consuming vast amounts of power in our day to day lives. Right now I am typing on a desktop computer with a 750W power supply. I have 2 monitors, at 60 W each. My hot water tank is turning on and off every hour or so, drawing another 750-1000 W. My fridge kicks on every once in a while, for another 500W. And this is just "overhead". I'm not cooking, I'm not ironing, I'm not running air conditioning. Therefore I would need around 7000W to run my house. At current prices, I am looking at at least $20k for just the solar panels. Then I need batteries, because solar only works during the day. Then I need to install and maintain the system.

          I really would love to do it. I have a roof, so surface area shouldn't be too much trouble. But price is a HUGE barrier to entry. Yes it pays for itself over time, but it's a steep up front cost. The price needs to come down for people to jump into solar, but people won't jump into solar until the price comes down. That's the "catch-22" that solar finds itself in.

    ... that someone has suggested setting off an underground nuke to close an oil well?

          So you are going to trigger a device that will reproduce the heat found inside the sun, and are worried about oil "catching fire"? That's like worrying about dropping a 2000lb bomb on the gas tank of a lawnmower. Please.

          Secondly oil does not "explode", it burns. Gasoline vapor explodes, but only in the presence of air because the reaction needs oxygen. Explosives explode because they contain the oxygen they need in their molecules. Nuclear weapons explode differently, they get incredibly hot and this heat causes a tremendous overpressure wave, as well as setting nearby things on fire. However nothing is oxidized in the bomb itself. Therefore it can happen in the absence of oxygen. The oil immediately around the blast would vaporize and burn - but then again so would some of the water and some of the nitrogen in the atmosphere. However the oil/water mix further out would not burn. I invite you to watch the Baker shot and try to see anything on the ship(s) burning. The water absorbs all the heat.

          Hell if you're worried about "fire" - remember that the damned oil rig was on fire in the FIRST PLACE. Where's the fire now?

          The water would be an excellent transmitter of the pressure wave, enough to shift the rocks and seal the well.

          I have a special request, however. All global warming and card-carrying Greenpeace members should be placed on a boat immediately above the device if this is going to happen.

    I'm only a mathematician, not an expert to anything but figments of the imagination

          OK, let's talk about the work-energy theorem and the amount of energy involved in lifting 1900 ships x 10 tons per second = 19,000 tonnes = (excuse me while I slip into scientific notation) 1.9 x 10^7 kg of water 1000 meters into the air every second. PE = mgh. So PE (using g as 10 instead of 9.8)= 1.9x10^7 x 10 x 1000 = 1.9 x 10^11 Joules per second, or 1.9 x 10^11 Watts. That's 190 GIGAWATTS. At 100% efficiency. However 100% efficiency does not exist. So let's be VERY generous and assume that the process (the pumps, etc) are 40% efficient. Therefore what you'd really need, at 40% efficiency, is 475 GW. 12 hours per day (assuming we're not going to run these suckers at night). So 365 x 12 hours = 4380 hours x 475 GW = 2080500 GW hours/year.

    Please note that the US energy consumption in 2008 was 3872598 GW hours per year. Therefore this concept (working at 40% efficiency remember) would consume more than HALF AGAIN AS MUCH POWER AS THE ENTIRE UNITED STATES.

    If you're a mathematician feel free to check my work. My source for us power consumption is Wikipedia. The rest is physics.

    Now I know I have been modded troll and flamebait - because the green crowd can't stand having anything said against their ideas. The problem is that any sane person is able to see through these crackpot ideas in under 30 seconds. Global warming cultists however (just like any other fanatic) have lost the ability to think rationally. Yes, I know about the albedo effect you mentioned. But run the numbers and you will realize that this is 1) impossible 2) impractical and 3, it will add heat to the system (all those non-frictionless pumps and energy sources you see) which means that I'm not sure the "benefit" from increased albedo effect would be offset from having an additional "United States" added to the world if the system was run 24/7.

          No. Traders are price takers, not price makers. A trader cannot create more profit out of thin air. A real middle-man like say, the guy at the record store, takes a $10 CD and sells it to you for $15, pocketing $5. He inflated the price. A trader on the other hand buys CD's when they are in plentiful supply (because some factory went crazy and dumped a billion CD's on the market). Because the supply increased, he scooped up the CD's cheap, for say $6. Then he waits until the supply excess is gone (everyone else jumps in and buys the CD's while they were cheap). Then you come along and you were too late to the party. You missed the $6 price. But I'm willing to sell you mine for $10. I make $4. You get a CD for $10. Market conditions change,and now there's a shortage of CD's, so suddenly they're worth $20. You sell your CD for $20 and make $10. So, have we been MAKING the price? No. We TAKE the price. The MARKET makes the price. But you can still make money.

    People don't understand this, they think that traders inflate the price. Not true. You can buy a block of AMR (American Airlines) right now for $6.83 per share. You can turn around and try to sell it right away for $50. It won't sell. The market makes the price not you. Your purchase of 100 shares of AMR did not budge the price one bit - in fact the way most trading algorithms are set up, the price probably DROPPED. Now it's trading for $6.82 after your purchase (supply and demand would have it go the other way, no? But you're dealing with brokers who are out to screw you). American airlines today has traded (as of right now) 20 million shares. Your purchase of 100, or even 10000 shares is a DROP IN THE BUCKET. It doesn't affect the price. Again, you are a price TAKER not a price MAKER. Now, when Fidelity Capital Appreciation Fund, who owns (today) 6.2% of America Airlines decides to dump 40 million shares on the market over the next 2 hours, well that DOES affect the price. Or when a stop loss is triggered for Goldman Sachs to sell $500 million worth of American Airlines when it hits a certain price, that DOES affect the price. But a little trader with $25k or $100k or even a million dollars - that's small fry. Not even a hiccup in the market.
