To combat climate change we must be brave – and spend money
You can't run your energy system on snake oil. As the predicted impact of climate change gets more frightening, the range and implausibility of proposed solutions grows in tandem.
They range from the relatively tame solutions such as storing carbon dioxide in undersea caves, to those that qualify for the slightly scary title of 'geoengineering'. These proposals include something called ocean iron fertilisation, or the idea of a 'sulphate aerosol shield' across the entire atmosphere. These are real proposals.
The attraction is obvious, because these kind of instant solutions offer the prospect of solving climate change at a stroke, with no financial implications and no need to change our lifestyles.
