Here's the whole article.



Increased output from the Sun might be to blame for 10
to 30 percent of global warming that has been measured
in the past 20 years, according to a new report.

  Maybe, Maybe not. But they don't disput that it
  happening.

Increased emissions of carbon dioxide and other
heat-trapping gases still play a role, the scientists
say.


  As claim most scientists around the world.


But climate models of global warming should be
corrected to better account for changes in solar
activity, according to Nicola Scafetta and Bruce West
of Duke University.

  Aboslutly, Science is an ongoing endevour.


The findings were published online this week by the
journal Geophysical Research Letters.

Scientists agree the planet is warming. Effects are
evident in melting glaciers and reductions in the
amount of frozen ground around the planet.


  And so, your support dwindles away to nothing.
  Dejavu?


The new study is based in part on Columbia University
research from 2003 in which scientists found errors in
how data on solar brightness is interpreted. A gap in
data, owing to satellites not being deployed after the
Space Shuttle Columbia disaster, were filled by less
accurate data from other satellites, Scafetta says.


   As time goes by even more data will be collected.
   Just how much is enough?


The Duke analyses examined solar changes over 22 years
versus 11 years used in previous studies. The cooling
effect of volcanoes and cyclical shifts in ocean
currents can have a greater negative impact on the
accuracy of shorter data periods.


   Good idea. More data will undoubtedly show even more
   support for global warming


"The Sun may have minimally contributed about 10 to 30
percent of the 1980-2002 global surface warming," the
researchers said in a statement today.


   Maybe (again) or maybe not (again)


Many questions remain, however. For example, scientists
do not have a good grasp of how much Earth absorbs or
reflects sunlight.


   This is about when not if global warming starts.

"We don't know what the Sun will do in the future,"
Scafetta says. "For now, if our analysis is correct, I
think it is important to correct the climate models so
that they include reliable sensitivity to solar
activity. Once that is done, then it will be possible
to better understand what has happened during the past
hundred years."

   If they succeed in delaying it long enough, they
   will have actually proof of global warming after
   it's too late to do anything about it
