Description :
Changes in solar constant over an 11 yr cycle suggest a certain, but limited, degree of solar forcing of climate. The high-resolution climate (oxygen isotope) record of the Greenland GISP2 (Greenland Ice Sheet Project 2) ice core has been analyzed for solar (and volcanic) influences. The atmospheric C 14 record is used as a proxy of solar change and compared to the oxygen isotope profile in the GISP2 ice core. Solar forcing during the surprisingly strong 1470 yr climate cycle of the 11,000-75,000 yr B.P. interval is rather hypothetical.
