Above slide from Dr. Kirby's lecture around 9:50 mark shows reconstructed solar activity over the past 6,000 years. Dr. Kirby's preceding slide in the lecture below shows extrapolated solar activity could reach levels of the Little Ice Age [LIA] within only 2 more years. Also shown are the peaks in solar activity corresponding to the Medieval Warm Period ~1000 years ago, the Roman Warm Period ~2000 years ago, the Egyptian and Minoan Wam Periods ~3000 and 4000 years ago, and the Current Warm Period of the 20th century.
Same reconstructed solar activity cited above by Dr. Kirby: Vonmoos et al 2006
