Description:
We present the results of a re-analysis of a previously published carbon isotope data-set related to coralline
sponges in the Caribbean Sea. The original interpretation led to the discrimination between a pre-industrial
period, with a signal controlled by solar-induced climatic variations, followed by the industrial era, characterized
by a progressive δ13C negative shift due to the massive anthropogenic carbon emissions. Our
re-analysis allowed to extract from the raw isotopic data evidence of a solar forcing still visible during the
industrial era, with a particular reference to the 88-year Gleissberg periods. These signals are related to
slope changes in both the δ13C versus time and the δ13C versus carbon emission curves.
