Do-It-Yourself: Solar variability effect on climate. Part II

Watts Up With That?

By Javier

In a previous article here, I showed how anyone with a computer with internet connection and Excel could check the basis of the 980-year periodicity in solar activity, known as the Eddy cycle, and its excellent match with a North Atlantic iceberg proxy record, known as the Bond series.

In this part I will show you how the same can be done with a proxy for the Asian Monsoon strength based on the deposition of δ18O in a speleothem from stalagmite DA from Dongge Cave in Southern China.

The scientific reference article for this is: “The Holocene Asian Monsoon: Links to Solar Changes and North Atlantic Climate,” by Wang et al., 2005, can be found here. It is a highly cited article, with 1750 citations in Google Scholar. This is by no means fringe science we are dealing with.

And the data for stalagmite…
