That CO2 versus growth experiment doesn't really give enough information. For example, it doesn't say how much water was available for the plants to use during their growth in different CO2 concentrations. Plants with lots of CO2 need less water, so in dry conditions, which is very often the case with plants, having lots of CO2 available reduces irrigation requirements and increases production. So not only does extra CO2 give more plant production, it does so even better in dry conditions. The luxuriant growth in those high CO2 samples shows that there is a major benefit from the CO2 produced by humans. It's not just a minor thing. Even if there are a few polar bears in trouble [which is not the case], I'd opt for millions or billions of people getting more food with less effort. Mqurice
