It turns out that Ohmura was the first to document a dramatic effect that scientists are now calling 'global dimming'. Records show that over the past 50 years the average amount of sunlight reaching the ground has gone down by almost 3% a decade. It's too small an effect to see with the naked eye, but it has implications for everything from climate change to solar power and even the future sustainability of plant photosynthesis. In fact, global dimming seems to be so important that you're probably wondering why you've never heard of it before. Well don't worry, you're in good company. Many climate experts haven't heard of it either, the media has not picked up on it, and it doesn't even appear in the reports of the Intergovernmental Panel on Climate Change (IPCC).
I will blog more on global dimming (the reduction in sunhsine not the dominance of George Bush) just as soon as I find a way to blame someone for it. I am thinking especially of people who break their eggs at the wrong end.
