New paper finds strong evidence the Sun has controlled climate over the past 11,000 years, not CO2

A paper published today 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 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 temperature

What more proof do you need that it's the Sun!

Very interesting reading, thank you for sharing this.

The warmists are getting increasingly hysterical and dogmatic, the more that the scientific basis for their hysteria is undermined. Scientists, however, are gradually taking note. I've noticed in my own field that acceptance for a strong solar influence on climatic variability is growing, in tandem with a tendency to roll eyes when warmists proclaim their faith.

Yes people are claiming they have power which in fact they do not possess. I mean honestly, if humankind would put every effort to raise the temperature all over the world by only one degree, could it be possible?
I am thinking definitely not. There are other influences with much greater magnitude.
The most false ideas are put into reality by the individuals that are good only at destroying everything that comes their way. But I am sure glad that the people start to be awake and are using their brains.

Yes, thanks for sharing that Eboard10. The evidence just keeps piling up - for people who base their views on evidence, that is....
