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

[Ted Moffett]

Excuse me?

You did not mention in your "Sunspots" post that in 2009 the solar
minimum was the deepest in nearly a century, nor mention that the
impacts on cooling global temperature that such a deep solar minimum
should have were likely overcome by other forcings in the climate
system, given that 2009 and 2010 were the second and first warmest
years for global average temperature in Goddard's temperature record
since 1880.

Given your emphasis on sunspot cycles having a major influence on
global temperature, to not mention the 2009 recent deep solar minimum,
and the associated global temperatures, is a major and puzzling
omission.

As far as you posing as a credible critic of NASA's climate scientist
James Hansen, pardon my intense skepticism.

At the website below from James Hansen read discussion indicating that
variations in solar irradiance associated with sunspot cycles do have
an impact on global temperature in short time frames, from year to
year, as does ENSO cycles, so the deep solar minimum of 2009, the
deepest in nearly a century, should have had an impact on 2009 or 2010
global temperature, even if small:

>From website above:

"The 5 year mean is sufficient to reduce the effect of the El Niño –
La Niña cycles of tropical climate. The 11 year mean minimizes the
effect of solar variability – the brightness of the sun varies by a
measurable amount over the sunspot cycle, which is typically of 10-12
year duration."
------------------------------

Also, please refer to a published climate science article in a
credible peer reviewed journal where in reference to Svensmark's
cosmic ray/cloud formation theory the phrase "shading the ground" is
used to indicate this is a major variable involved in cooling or not
of the Earth's climate due to cosmic ray cloud formation variables.

Good luck!
