New paper finds strong evidence the
Sun has controlled climate over the past 11,000 years, not CO2
THE HOCKEY SCHTICK If you can’t explain the ‘pause’, you
can’t explain the cause…
A paper published today (December, 2014) in Journal
of Atmospheric and Solar-Terrestrial Physics
finds a “strong and stable correlation” between the millennial variations
in sunspots and the temperature in Antarctica over the past 11,000 years.
In stark contrast, the authors find no strong or stable correlation
between temperature and CO2 over that same period.
The authors correlated reconstructed CO2 levels,
sunspots, and temperatures from ice-core data from Vostok Antarctica
and find
“We find that the variations of SSN [sunspot number] and
T [temperature] have some common periodicities, such as the 208 year
(yr), 521 yr, and ~1000 yr cycles. The correlations between SSN and T are
strong for some intermittent periodicities. However, the wavelet analysis
demonstrates that the relative phase relations between them usually do not
hold stable except for the millennium-cycle component. The millennial variation of SSN leads
that of T by 30–40 years, and the anti-phase relation between them keeps stable
nearly over the whole 11,000 years of the past. As a contrast, the correlations
between CO2 and T are neither strong nor stable.”
Thus, the well known ~1000 year climate cycle responsible
for the Holocene Climate Optimum 6000 to 4000 years ago, the Egyptian warm
period ~4000 years ago, the Minoan warm period ~3000 years ago, the Roman warm
period ~2000 years ago, the Medieval warm period ~1000 years ago, and the
current warm period at present all roughly fall in this same 1000 year
sequence of increased solar activity associated with warm periods.
The
authors find a lag of 30–40 years between changes in solar activity driving
temperature, likely due to the huge thermal capacity and inertia of the
oceans. Lead time shown in bottom graph of 40 years shows the temperature
response following an increase or decrease of solar activity lags by about
40 years. Top graph shows “the anti-phase relation between [solar activity
and temperature] keeps them stable nearly over the whole 11,000 years of
the past.”
The authors find temperature
changes lag solar activity changes by ~40 years, which is likely due to the
huge heat capacity and inertia of the oceans. Warming proponents attempt
to dismiss the Sun’s role in climate change by claiming 20th century solar
activity peaked at around 1960 and somewhat declined from 1960 levels to the
end of the 20th century (and have continued to decline in the 21st century
right along with the 18+ year “pause” of global warming).
Firstly, the assumption that solar activity peaked in 1960
and declined since is false, since it is necessary to determine the accumulated
solar energy over multiple solar cycles, which is the accumulated departure
from the average number of sunspots over the entire period, which I call the
“sunspot integral.” The sunspot integral is plotted in blue and shows remarkable
correction with global temperatures plotted in red below. Correlating
sunspot and temperature data with and without CO2, we
find the sunspot integral explains 95% of temperature change over the past
400 years, and that CO2 had no significant influence (also here).
Secondly, this paper finds strong evidence of a 30–40 year
lag between solar activity and temperature response. So what happened ~40
years after the 1960 peak in sunspot activity? Why that just so happens to be
when satellite measurements of global temperature peaked with the 1998 El
Nino [which is also driven by solar activity], followed by the “pause” and
cooling since.
We have thus shown
- Strong correlation between solar activity and climate over the past 11,000 years of the Holocene
- Strong lack of correlation between CO2 and climate over the past 11,000 years of the Holocene
- Solar activity explains all 6 well-known warming periods that have occurred during the Holocene, including the current warm period
- The 20th century peak in sunspot activity is associated with a 40 year lag in the peak global temperatureBut wait, there’s more. Please see the two previous posts demonstrating that the alternate 33C greenhouse effect is due to atmospheric mass/gravity/pressure, not CO2 or water vapor, physical proof & observations that water vapor is a strong negative-feedback cooling agent, and physical proof that CO2 cannot cause any significant global warming. All of the above also strongly suggests the increase in CO2 levels is primarily due to ocean outgassing from warming oceans from the Sun, not from CO2 radiative forcing warming the oceans, and not primarily from man-made CO2 emissions.X.H. Zhao, X.S. Feng• SSN [Sunspot Number] and Vostok temperature (T) had common periodicities in past 11,000 years.
• The millennial variations of SSN and T had a strong and stable correlation.
• The millennial variation of SSN led that of T by 30–40 years.
• Correlations between CO2 and T were neither strong nor stable.Abstract
The solar impact on the Earth’s climate change is a long topic with intense debates. Based on the reconstructed data of solar sunspot number (SSN), the local temperature in Vostok (T), and the atmospheric CO2 concentration data of Dome Concordia, we investigate the periodicities of solar activity, the atmospheric CO2 and local temperature in the inland Antarctica as well as their correlations during the past 11,000 years before AD 1895. We find that the variations of SSN and T have some common periodicities, such as the 208 year (yr), 521 yr, and ~1000 yr cycles. The correlations between SSN and T are strong for some intermittent periodicities. However, the wavelet analysis demonstrates that the relative phase relations between them usually do not hold stable except for the millennium-cycle component. The millennial variation of SSN leads that of T by 30–40 years, and the anti-phase relation between them keeps stable nearly over the whole 11,000 years of the past. As a contrast, the correlations between CO2 and T are neither strong nor stable. These results indicate that solar activity might have potential influences on the long-term change of Vostok’s local climate during the past 11,000 years before modern industry.Related Posts
