Time-Delayed Response of the Solar Total Irradiance Variation to Long-Term Solar Magnetic Cycle Amplitude Modulation as Inferred by Sunspot Relative Number and Isotope Data of ¹⁰Be in the Greenland Ice Core and Land Air Temperature Variation of the Earth

Abstract

We found that the time profile of the land air temperature anomalies followed the time profile of the magnetic field variation with remarkable similarity and delay time of about 200 years for both cases of the instrumentally measured temperature data and the data reconstructed from tree ring growth rates of the northern north American continent and the polar Ural mountains of northern Siberia. If this is indeed the case, (i) the present global warming will turn to global cooling in near future. If we assume that the land air temperature anomalies can be a good proxy of the solar total irradiance variation, the present result means that (ii) the present global warming of the Earth is a result of release of heat which has been stored in the solar convection zone in the Maunder Minimum in the 17th century.
