The forecasts for China's need for petrol alone in the coming decade is staggering, and when the production of an average car is 20 metric tonnes of carbon then the figures start going exponential. If we all switch to electric cars then we must have nuclear - nothing else could cope with the demand. This being said, we must always try something different - attempts to produce hybrid fuel from algae so we don't have to tear down the rainforests seems like a good example - people tend to pour derision on these schemes without offering alternatives.
Then again, there is nothing more disconcerting than when protesters are portrayed in a similar light as a Chinese fire drill.
I get worried about the rate the glaciers are melting at, but then they've been there for millions of years, and maybe encountered this many times in the past.
We must keep trying, because if we don't, then we have failed.
