 VH> The Sun is burning brighter than at any time over the past 1,150 years,
 VH> according to a study by a professor at a Swiss university.
 VH> Professor Sami Solanki said this could be compounding the effects of
 VH> greenhouse gases and contributing to global warming.
 VH> Sunspots appear to be intensifying the sun's brightness and energy
 VH> output (zebulon1er)

 VH> "We have to acknowledge that the Sun is in a changed state. It is
 VH> brighter than it was a few hundred years ago, and this brightening
 VH> started relatively recently - in the last 100 to 150 years. We expect it
 VH> to have an impact on global warming," he told swissinfo.

 VH> Last week Solanki, who is a professor at the Federal Institute of
 VH> Technology in Zurich, presented the findings at a conference of solar
 VH> and stellar scientists in Hamburg, Germany.

 VH> His research team reached its conclusions after studying data from
 VH> samples of ice collected by Swiss scientist Jürg Beer on an expedition
 VH> to Greenland in 1991.

 VH> Most scientists acknowledge that greenhouse gases from fossil fuels have
 VH> warmed the planet in past decades, but they have questioned whether a
 VH> brighter Sun is also responsible for rising temperatures.
 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.

I have pointed out the facts you have here to people and they still insist
it's because we didn't sign that treaty.
It's at that point I just usually say "I don't need to waste my time talking
to fools."
I don't care anymore if it pisses them off.
