I was under the impression that we were all in agreement, that climate change is happening and it's out fault. But according to Channel 4's documentary this evening, we've all been conned. Apparently, although historical rises in CO2 do match rises in temperature, it's the rises in temperrature that drive the rises in CO2 rather than the other way round. I get the feeling that if this were the case, there would be a few more dissenting voices in the scientific community so I won't be going out to buy a mechanical hippo tomorrow. Even if it is true, the fact is fossil fuels will run out one day so we have to find alternatives, and the sooner we start to do that the better.
