Global Dimming

Just to make things more complicated.

"We are all seeing rather less of the Sun. Scientists looking at five decades of sunlight measurements have reached the disturbing conclusion that the amount of solar energy reaching the Earth's surface has been gradually falling. Paradoxically, the decline in sunlight may mean that global warming is a far greater threat to society than previously thought.

The effect was first spotted by Gerry Stanhill, an English scientist working in Israel. Comparing Israeli sunlight records from the 1950s with current ones, Stanhill was astonished to find a large fall in solar radiation. "There was a staggering 22% drop in the sunlight, and that really amazed me," he says......"

I remember years ago my gran said those planes will ruin the atmosphere! Looks like you are right, sorry gran for not believing you.

After 911 Dr David Travis from the University of Wisconsin, Whiterwater noticed how incredibly blue and clear the skies were and unusually clear. He was researching for 15 years were the vapour trials left by aeroplanes affecting the climate (he must have heard my gran). In the aftermath of 911 the entire US fleet were grounded (aside from the bin laden family and other friend of G.W. Bush of course). He thought that the ground might make a tiny affect. He found the change in temperature range over the the days there was a change in over 1 degree in three days. None had ever seen such a big change in such a short change. This was not at the ground level but in the atmosphere where the climate is more static and constant. Take a look at the video and think some more.
