I said it would happen, I didn't say that it had anything to do with Katrina.
It still does, though. One could easily argue that the warmer water is caused by global warming and that Katrina's power was caused by warmer water. Whether you said it would or would not, it did.

Yeah, and if I only go back 2 hours ago, there's a clear cooling trend.
So you could probably accurately predict that, in the next .1108 seconds, it will continue to cool, correct? That's what's going on. You don't need a billion years of data to predict the next 100 years. I see your point, but there's no reason 650,000 years isn't enough data to project the next 100 years. In other words, using the 2 hour example, you should be able to project the next .1108 seconds; compare this to using 650,000 years to project the next 100 years (yes, I did the math).

I could buy into that a single example; but there's a point when he's talking about temperatures while still displaying the CO2 graph (at a 45 degree angle) while he's talking. Why not show the near flat temperatue chart? because, if you look at the whole history of global terperatures, right now it would pretty much be flat.
Probably true, but not really usable in an argument since you have no idea what the actual temperatures were for the whole history of global temperatures.
Just because one rises more quickly than the other doesn't mean it isn't a cause. If you were to graph the number of extra calories consumed in a day to daily weight gain, the graphs certainly wouldn't be identical. In fact, daily weight gain would look relatively flat. But that doesn't mean you can rule out the extra calories as being the cause, or rule out a correlation.
Besides, ppm of CO2 can be measured directly with little other influencing factors; global temperature is affected by many more things and involves the changing of an equilibrium that is most likely much more intricate than trees consuming CO2 and humans producing more of it.

Who's talking about intelligent design. If you leave a glass of ice cubes in a room who's ambient temperature is 70 degree is supposed to melt at a certain rate. Don't nitpick.
That was actually just so you wouldn't nitpick. You can ignore it if you aren't going to. I was just using the phrase 'supposed to' literally, as if someone had planned it, nothing significant.
DOMS said:
Yet the CO2 is on his graph and he's talking about a clear correlation, which falls apart near the right end.
I see what you're saying, now. Yes, the correlation certainly isn't as strong near the end (and thankfully so). This leads me to wonder if there is something else which links the CO2 and temperature. However, I think exercising the option of not investigating something with such potentially devastating consequences is beyond foolish.
I'll have to watch it again sometime and pay special attention to the graphs. I kept thinking he would return to explain things (when he wasn't talking about the farm) and then eventually forgot about them.

If this were 100% true, and the CO2 levels are through the roof, then were is the corresponding meteoric rise in tempurates? So far they seem to be following an historic trend that started 10,000 years ago and not CO2 levels.
Again, correlation doesn't mean both are linear or that both will be at the same rate. Correlations in nature are often not perfect, either. Increased CO2 is a fairly easy thing to do. Changing the temperature of so much water and land is extremely difficult due to the rather high specific heat of water and the sheer amount of it. It's evident that temperature will not be able to keep up with the rapid rate at which the CO2 is increasing.
Put a pot of water on the stove with a very small flame: The temperature of the water and the amount of heat you are producing from the flame will probably both climb at a fairly steady rate. Now quadruple the flame. The amount of heat produced will increase more rapidly than the temperature of the water for a while: There is a lag time due to the amount of heat it takes for the water to heat up. I think that may be what's happening here.
Again, if you want to compare a historic trend that started 10,000 years ago, that is addressed in the graphs. The graphs show the trends of ice ages and melting periods a total of seven times. The spike in CO2 here is several times larger than other spikes. If the lagging effect is indeed what's happening, that's not a good thing. If that's not what you were talking about, please specify the trend to which you're referring, keeping in mind that the natural cycle of ice age and warmth is very small compared to what we are currently experiencing. (Or was that graph only of CO2? I honestly don't remember.)
