The UN's IPCC
could not care less
about the effect
of solar variations
on our planet's climate.
IPCC climate models
exclude any effect
the sun could have,
and then assume CO2
has a large effect
on the global average
temperature .
Their climate models
predict a much larger
temperature increase
than has been observed
over the past two decades.
When the sun has gusts
in the solar wind, it causes
several day long reductions
in the flux of cosmic rays
reaching Earth, called
Forbush decreases.
We then see changes
in airborne aerosols
and cloud properties.
There are also
large cosmic ray
flux variations over
geological time
scales related
to our location
in the Milky Way.
Scientists can
reconstruct the
cosmic ray flux
using meteorites
and find that the
7 ice-age epochs,
over the past
one billion years,
all appeared when
the cosmic ray flux
was high.
The IPCC
can not
find a link
between the sun
and climate change,
but they are not
looking for one.
