Global Warming not caused by the Sun or cosmic rays
'No sun link' to climate change
A new scientific study concludes that changes in the Sun's output cannot be
causing modern-day climate change. It shows that for the last 20 years, the
Sun's output has declined, yet temperatures on Earth have risen. It also shows
that modern temperatures are not determined by the Sun's effect on cosmic rays,
as has been claimed.
