Island in Cairo. These records were then compared to another well-documented human record from the same time period: observations of the number of auroras reported per decade in the Northern Hemisphere. Auroras are bright glows in the night sky that happen when mass is rapidly ejected from the sun's corona, or following solar flares. They are an excellent means of tracking variations in the sun's activity.... The researchers found some clear links between the sun's activity and climate variations. The Nile water levels and aurora records had two somewhat regularly occurring variations in common -- one with a period of about 88 years and the second with a period of about 200 years. GAI: Yes, Leif is in de-Nile on that one. The Gleissberg and de Vries cycles are evident. Looking at the ACRIM plot and the deep dive TSI took at SC23/24 minimum, the Sun is a good deal more variable than Leif wants us all to think it is. _______________________________ If the Russian Solar Physicist is correct the West is going to be in very deep... snow rather shortly. I would not want to be a politician when the fecal material hits the rotating blades. 28gate will take wings at that point. They can only keep covering this up for so long but the incredible stupidity of the sheeple sometimes makes me wonder. After you remove the long term reconstructions, you can his reconstruction from 2008 quite clearly, and the strangely low value at 2007.5 which is lower
