I see what your saying and they are both interesting points, but the fact of the matter remains. I we (as a society) don't cut our emissions by at LEAST 60% before 2050 then we will have reached the point on no return.

The methane in the ice caps would be released, the gulf stream will shut down and there will be nothing we can do about it. Some people actually think we have gone past the point of no return, but I like to have some bit of hope that the human race can save itself somehow.

But if 60% at the least is needed, what hope is there is we (in the the UK) can't even reduce by 3% since 1997 and actually end up increasing our emissions.

There are those who say that going Nuclear is the only way because it emits almost no CO2. That may be true, but there are other points to look at. For one, the is the risk of the radioactive waste that it produces that we are still not sure where to store. Then there is the the fact that climate change is happening now, and a solution is needed now. Nuclear power stations take about 10 years to be built and become operational so by then I fear it may be too late.

Remember what Thom Yorke said, this is a last ditch attempt from a dying industry so be prepared to hear all sorts just so they can try and save their skin. We need to start spending serious money in green energy and not just token gestures.

I would be interested to hear a US opinion about how they over the water are doing their bit.
