[Vision2020] Sunspots: 2009 Deepest Solar Minimum in Nearly A Century, Then 2010 Warmest Year in 131Years

The subject heading sums up the main point of this post.

Odd (well, not really, actually what I've come to expect) that given
your in-depth (?) research into solar activity and its relation to
Earth's climate, you make no mention, in your sunspot comments below,
of the very significant recent deep solar minimum in sunspot activity
in 2009, the deepest solar minimum in nearly a century, according to
NASA: "This is the quietest sun we've seen in almost a century,"
agrees sunspot expert David Hathaway of the Marshall Space Flight

During and just after this deep solar minimum, Earth's average surface
temperature in 2009 and 2010 remained among the top ten warmest years
in the 131 year instrumental record from the Goddard Insitutue for
Space Studies.

In fact, 2010 was tied statistically with 2005 as the top warmest year
in 131 years, according to GISS:

The following article from the Earth Institute at Columbia University
mentions the 2009 deep solar minimum impacts on global temperature:
2000-2009: The Warmest Decade:
 "In 2009, it was clear that even the deepest solar minimum in the
period of satellite data hasn't stopped global warming from
continuing," said Goddard Institute for Space Studies director Dr.
James Hansen.
In 2009, during this deep solar minimum, there was speculation in the
scientific community that we could be entering a prolonged period of
very low solar activity, that "...sunspots could completely vanish
around the year 2015."

But this did not occur.  Solar cycle 24 has seen an increase in
sunspot activity, with sunspot activity predicted for 2015 above the
2009 deep solar minimum.

There are always a wide variety of theories and speculations occuring
in the science community on many issues.  Those with a biased agenda
cherry-pick the theories and research to suit their confirmation bias
filter, and conveniently ignore a balanced consideration of all the
scientific research.

Your depiction of the cosmic ray/cloud formation impacts on cooling
the Earth's is misleading.  Given my reading on this scientific issue,
"shading the ground" is not a major impact of cloud formation
associated with cosmic rays on temperature, though changes in albedo
