It would be nice to think that George Bush was watching the UKTV History channel last night. Somehow I don't think he was, but when he reads this he'll know what it was all about.
'Meltdown' was a part of a series on climate change. The big question is - given that we know beyond doubt that the planet is heating up, how much can be attributed to natural variations and how much can only be explained by man made effects?
For thousands of years the temperature of the Earth was governed by two main drivers: the solar cycle (i.e. variations in the sun's output) and the amount of volcanic activity which affects the amount of dust in the atmosphere and hence the amount of sunlight that can penetrate. The match between the actual temperature and the predicted temperature is stunning - until you get to the last 150 years. The increase of greenhouse gasses and with it the global temperature has been in liftoff, tracking the course of the industrial revolution and consequent carbon emissions.
Surprisingly one of the big voices in the debate in America putting pressure on the White House Muppet has been Big Energy. Surprising? Yes, until you realise that they own massive infrastructure and they need to be able to plan their businesses. They know that carbon emission caps will be arriving sooner or later, but until they have a regulatory level playing field it is hard for them to know how to invest their shareholders' capital.
