3. What Is the Solar Impact on Climate Change (if
any?!)
1. Does climate change (i.e. global warming or cooling) correspond
in time to changes in some solar cycle?
If so, is the climate change actually caused by the solar changes?
Most likely candidate: Sunspots (w/ maximum
in x-ray and UV)? |

High times of solar activity occur every
22 years (11 years to maximum and 11 back to minimum). There
is a measurable change in solar radiation due to changes in
the number of sunspots. But a change that takes place in only
11 years is not a realistic explanation for the spikes that
we see in global climate changes. |
2. Is this really long-term climate change?!
We’ve been observing the sun for centuries (at most), and only
for a few decades with high-technology equipment. Geologists generally
don’t consider change over a decade or two to be climate change.
