Climate change may be happening much faster than we imagine. Global dimming appears to be masking the true extent of the global warming that is underway. The prestigious BBC programme ‘Horizon’ reports on ‘Global Dimming: the phenomenon by which the earth is cooled by man-made particulate pollution in the atmosphere,  inlcuding the vapour trails left behind by aircraft, which spread out and reflect sunlight, keeping the planet cooler. As we clean up our emmissions we may find that warming has been masked, leading to a faster rise in global temperatures than previously expected.
