Paper finds solar activity at end of 20th century was highest in 9,400 years A recent paper published in the Proceedings of the National Academy of Sciences examines ice core and tree ring radionuclides and finds solar activity at the end of the 20th century was at the highest levels of the record spanning the past 9,400 years.
