This 2007 BBC program Dimming the Sun investigates the discovery that sunlight reaching Earth has been growing dimmer in recent years, a surprising result given all the media concern over global warming.
Somewhat less sunlight might seem a good thing on a world stewing in greenhouse gases. Yet the discovery of global dimming has caused many scientists to revise their earlier models of the climate, and how fast our climate is really changing. According to one recent and highly controversial model, the worst-case warming scenario could be more devastating than anyone had previously predicted.
This fascinating BBC episode on Dimming the Sun considers still another disturbing aspect to the whole climate change conundrum, along with continued real world implications for our fragile Earth’s potential future.
