act globally

What happens if we fail to reduce our carbon emissions fast enough to stop catastrophic climate change? Some scientists, such as the Nobel laureate Paul Crutzen, think that we may end up having to "engineer" the climate at a global scale in order to compensate for our failing and to avert catastrophe.

Last month, an official report commissioned by the UK's science academy, the Royal Society, has moved this subject closer to scientific respectability, and assessed the options. Note, however,that this is strictly a plan B, not an excuse for doing nothing about the CO2 emissions.
