Evidence of the previously unknown phenomenon of Global Dimming, one that scientists believe could dramatically alter global temperatures

Climate scientists have discovered a phenomenon that threatens to disrupt our world. It may already have contributed to the deaths of hundreds of thousands through drought and famine. Unchecked, it will strike again. The good news is that there is a cure. The bad news is that the cure may be worse than the disease. If scientists are right, then we may be about to unleash a climate catastrophe on our planet the like of which it hasn’t experienced in its 4 billion years. This is a film about stark choices and about the dawning realisation that all our predictions about the world’s climate may be wrong. At its heart is something that scientists are calling “global dimming”.
