 VH> Global warming
 VH> Average global temperatures have increased by about 0.2 degrees Celsius
 VH> over the past 20 years, and are widely believed to be responsible for
 VH> new extremes in weather patterns across the world.

 VH> According to scientists, the Sun's radiance has changed little during
 VH> this period. But looking back over 1,150 years, Solanki found the Sun
 VH> had never been as bright as in the past 60 years.

 VH> The indirect impact of more intense sunshine on the ozone layer and of
 VH> solar activity on cloud cover may be affecting the climate more than the
 VH> sunlight itself, he said.

 VH> "The change in solar brightness over the past 20 years is not enough to
 VH> cause the observed changes in our climate. But the indirect effects may
 VH> be larger, and the range of their influence is unclear, so more study is
 VH> needed," he added.

 VH> To see whether a brighter Sun is warming the planet, solar scientists
 VH> have measured magnetic zones on the Sun's surface, called sunspots.

 VH> Sunspots appear to intensify the Sun's brightness and energy output, and
 VH> their numbers are associated with climate, said Solanki, who is also
 VH> managing director of the Max Planck Institute for Solar System Research
 VH> in Germany.

 VH> Looking back over several hundred years, Solanki's team found that not
 VH> only did a dearth of sunspots signal a cold period - sometimes for as
 VH> long as 50 years - but they also discovered that the number of sunspots
 VH> increased over the past century as the Earth's climate grew steadily
 VH> warmer.

 VH> "All in all, I think we are coming to a point where we acknowledge that
 VH> both solar activity and greenhouse gases are important factors in the
 VH> change in the Earth's temperature," he said.

Yup, its all Bush's fault!  If you don't believe that, just hide and watch
because Bob will be telling us so in short order.
