Yes, a lot of AGW alarmists oppose geo-engineering of any sort, on the basis that it might enable us to go on using fossil fuels. By that, they betray their true intents -- to bring down modern civilization.

However, this "ocean fertilization" (like all geo-engineering) has the potential to be disastrous on a grand scale. If it works as anticipated; just a couple thousand tons or so of iron filings could remove a lot of C02 from the atmosphere. Potentially enough to set off a new ice age -- which would be a far, far worse scenario than the worst case for global warming.

To see why this is the case, look at the graph below:



Did you notice that the greenhouse effect of C02 is logarithmic. If you double the amount of C02 in the atmosphere, you only increase the greenhouse effect by about 30%. The greenhouse effect of C02 is almost maxed out (that's something the alarmists don't want you to know). However, if you reduce the amount of C02, you move to the steeper left side of the graph. Cut the amount of atmospheric C02 in half, and we're in the next ice age. Do you trust envrio-fascist fanatics to not overshoot the mark?

I’ve seen that chart and I agree, too little CO2 is much more dangerous than too much. We have to consider the fact that the earth was CO2 starved in the past million years or so. It is one of the reasons that grasses evolved (they can thrive in low CO2 conditions).

Do you have a link (site) for that graph? I’d love to have it to pass around.
