A German climate researcher has discovered that the surge in solar radiation that began in 1700, peaked in 1960 and is still at historically high levels was far stronger and more significant than had previously been realized.
According to Dr. Horst-Joachim Lüdecke, who spent months comparing the varying widths of annual tree-rings and stalagmite deposits with recent temperature and sunspot records, this remarkable increase in solar activity was the real reason why the weather got warmer from 1950-2000. There has been no warming since 2000.
