    Irish Chronicles Document Links Between Volcanoes and Weather

    A study of over 40,000 written entries in Irish Annals and ice core measurements shows a strong correlation between the occurrence of volcanic eruptions and extreme cold weather in Ireland over a 1200 year period. Data analyzed in this study cover the period from 431 to 1649, during which time up to 48 volcanic eruptions are identified in Greenland ice core records through deposition of volcanic sulfate in annual layers of ice. You can find the study (open access), published on 6 June 2013 in IOP Publishing's journal Environmental Research Letters, at http://iopscience.iop.org/1748-9326/8/2/024035/article.

    Atmospheric CO2 Level Tops 400 ppm

    During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well. The level of atmospheric greenhouse gases continues to increase, now over 120 ppm since the Industrial Revolution began. For more on the Keeling Curve, see http://keelingcurve.ucsd.edu/.

Mercury and the Birth of Bacchus

Mercury was popular among the gods because he was playful, innocent, and helpful. Mercury helped his father, Jupiter, when Bacchus was born. Bacchus was the son of Semele and Jupiter. Semele was the daughter of Cadmus, the brother of Europa, and Harmonia, the daughter of Mars and Venus. When Jupiter and Semele first got to know each other, Jupiter was disguised in simple clothes. Jupiter's wife, Juno, was angry with both Jupiter and Semele. Juno disguised herself as Semele's nurse and made Semele curious about her new boyfriend. The next time Jupiter visited, Semele made him promise that the next time he came, he would come to her as he really was. On his next visit, he came as the god Jupiter, and Semele was consumed to ashes by his brillance. Jupiter took Semele's baby, Bacchus, and nurtured him until he was ready to be born. Once he was born, Jupiter gave Bacchus to Mercury to protect the baby from Jupiter's wife, who was jealous. Mercury put the baby Bacchus in the care of Io, Semele's sister.
