«If we figure out
how much atmosphere is removed by
changes in solar activity, we can extrapolate back to estimate what the isotope ratios should have been billions of years ago.
There are a large number of recent peer - reviewed scientific publications demonstrating
how solar activity can affect our climate (Benestad, 2002), such as
how changes in the UV radiation following the
solar activity affect the stratospheric ozone concentrations (1999) and
how earth's temperatures respond to
changes in the total
solar irradiance (Meehl, 2003).
I particularly enjoyed the slides that, when combined (1) provided an overview of hotter and cooler CO2 molecules as it relates to
how they are seen from outer space and from profile — because this will make it easier for me to explain this process to others; (2) walked through the volcanic and
solar activity vs assigning importance to CO2
changes — because this another way to help make it clearer, too, but
in another way; (3) discussed CO2 induced warming and ocean rise vs different choices we might make — because this helps point out why every day's delay matters; and (4) showed Figure 1 from William Nordhaus» «Strategies for Control of Carbon Dioxide» and then super-imposed upon that the global mean temperature
in colors showing pre-paper and post-paper periods — because this helps to show just
how far back it was possible to make reasoned projections without the aid of a more nuanced and modern understanding.
When we do, no matter
how good the climate model is it will not be able to overcome deficiencies
in our ability to predict the things that affect climate —
solar activity, ocean cycles, etc — and it will not be able to overcome deficiencies
in our understanding of
how things that affect climate actually work —
solar activity, Earth orbital
changes, etc..
You have not cited a third possibility (out of the infinite range of possibilities), no climate
change associated with CO2 (due to, for example, cloud cover providing negative feedback), with current increase due to natural variability; or
how about possibility four, that increase
in CO2 concentrations are caused by the temperature rise, which is
in turn caused by (for example) increased
solar activity resulting
in increased biomass
activity etc. etc..
In the 1990s, he proposed a theory to explain how slight changes in solar activity could cause large changes in global temperatur
In the 1990s, he proposed a theory to explain
how slight
changes in solar activity could cause large changes in global temperatur
in solar activity could cause large
changes in global temperatur
in global temperature.
In particular, given that there has been no trend in the sunspot count or cosmic ray flux over the last 50 years [1], while the global temperature has increased by 0.5 - 0.6 °C [2], how can one seriously claim that your work shows solar activity to be the major driver of climate change today and over the last 50 year

in the sunspot count or cosmic ray flux over the last 50 years [1], while the global temperature has increased by 0.5 - 0.6 °C [2],
how can one seriously claim that your work shows
solar activity to be the major driver of climate
change today and over the last 50 years?
Other studies have examined
how the global temperature has
changed in response to
changes in solar activity.
The study of
solar cycles and their climatic effect is hampered by a very short observational record (~ 400 years), an inadequate understanding of the physical causes that might produce centennial to millennial
changes in solar activity, and an inadequate knowledge of
how such
changes produce their climatic effect.
My Hot Water Bottle Effect shows
how any apparently minor
changes in solar activity can be supplemented or offset to match the observed
changes in global temperature trend during the latter half of the 20th Century.
If so,
how does the current statement of «
solar activity leading to cooling» reconcile with the previous description of the last century's temperature
changes as described
in the original, 2008 article?
Thus
solar activity has associated positive feedback when more active and negative feedback when less active, dramatically magnifying Earth's thermal response to
changes in solar activity and explaining
how fractions of Wm - 2
change in direct
solar radiation translate to many Wm - 2 effect between positive and negative phases of relative
solar activity.
