Why is the sun dimming?

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.

This phenomenan is called global dimming. No one is sure what's causing global dimming – or what it means for the future.

The decline in sunlight reaching the surface of the earth may mean that global warming is a far greater threat to society than previously thought.

This is bad news. It should be a concern not only to the climate scientists but to the global community as a whole.

While scientists may find difficult to prove the causes of this 'dimming,' we know there is global warming and the various forms of pollution that affects the environment. So for sceptics and critics alike, it may be time to take a good hard look and understand what challenges lie ahead.
