Global Dimming Tragic End of Humanity?
BBC Horizons (50 min 7 sec)


ABSTRACT


We are all seeing rather less of the Sun, according to scientists who have been looking at five decades of sunlight measurements. They 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.




Friends of Science Society (24 min 35 sec)


ABSTRACT


At a news conference held in Ottawa, some of North America's foremost climate experts provided evidence demonstrating that the science underlying the Kyoto Protocol is seriously flawed; a problem that continues to be ignored by the Canadian government. Scientists called on the Canadian government to delay implementation of the Kyoto Protocol until a thorough, public review of the current state of climate; science has been conducted by climate experts. Such an analysis has never been organized in Canada despite repeated requests from independent, non-governmental climate experts.

You should have taken notes and for revision compare the two contrasting stand points.
