More Evidence (Again) It’s The Sun

The evidence that the sun is the major driver in climate change keeps growing. Here is an article by P Gosselin, at The NoTricks Blog.

Roman climate driver.

A reader brings our attention to a paper published by the Quaternary Science Reviews, authored by Liang Chen, Karin A.F. Zonneveld, and Gerard J.M. Versteegh of the University of Bremen: Short term climate variability during “Roman Classical Period” in the eastern Mediterranean.

This one is about a temperature reconstruction from Southern Italy going back 2000 years. The abstract states:

Climatic and environmental reconstructions based on a dinoflagelate cyst record from a well dated site in the Gulf of Taranto located at the distal end of the Po-river discharge plume have been established with high temporal resolution in order to obtain insight into potential forcing of short-term climatic and oceanographic variability in the southern Italian region during the “Roman Classical Period” (60 BC – AD 200).

So how much does the reconstruction say us humans and our CO2 emissions have warmed the planet since the Roman days? Here’s what the abstract concludes (emphasis added):

The dinoflagellate cyst association indicates that local sea surface temperatures which in this region are strongly linked to local air temperatures were slightly higher than today. We reconstruct that sea surface temperatures have been relatively high and stable between 60 BCeAD 90 and show a decreasing trend after AD 90.”

It was warmer back then!  Gee, did greenhouse gases cause the warming during the time of the Romans? What could it have been, we all wonder? Stop wracking your brains, the answer is:

Fluctuations in temperature and river discharge rates have a strong cyclic character with main cyclicities of 7 – 8 and 11 years.”

11 years? Now why does this number sound familiar? Could it have anything to do with a certain solar cycle that is very well known (at least outside of the IPCC)? The abstract continues:

We argue that these cycles are related to variations of the North Atlantic Oscillation climate mode. A strong correlation is observed with global variation in delta14C anomalies suggesting that solar variability might be one of the major forcings of the regional climate. Apart from cyclic climate variability we observed a good correlation between non-cyclic temperature drops and global volcanic activity indicating that the latter forms an additional major forcing factor of the southern Italian climate during the Roman Classical Period.”

Yet another reconstruction showing the sun at work. Today, however, the sun doesn’t do anything. At least that’s what the experts at the IPCC would like to have us believe.

In history a quiet sun has produces cooler temperature on this planet. Long term lack of sun spots produced the Maunder Minimum and the Dalton Minimum.  The article is more evidence that we should continue to watch the sun.
