    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/.

Nicolas Poussin: "The Infant Bacchus Entrusted to the Nymphs of Nysa; The Death of Echo and Narcissus" (1657). The painting shows Mercury (in Greek, Hermes) delivering the newly born baby Bacchus (in Greek, Dionysus) to the nymphs of Nysa. The Hyades were also called the nymphs of Nysa because they lived on Mount Nysa.

Hyades

For the ancient Greeks, the Hyades were daughters of Pleione and Atlas, a giant who carried the heavens on his shoulders. The Hyades had several sisters, such as the Pleiades and the Hesperides. They were very attached to their brother Hyas. One day, while Hyas was hunting, he was killed by a lion. The Hyades were so overcome with grief they committed suicide.

Zeus changed them into a cluster of stars and placed them in the constellation Taurus the Bull. Zeus was grateful to them because they nursed his son the god Dionysus. One of the Hyades, Aldebaran, is the brightest star and represents the Bull's eye. The other Hyades are in a V-shape, forming the horns and the nose of the bull.

Because the Hyades appear during rainy seasons, the Greeks believed them to be messengers of spring rain showers and autumn storms. Their name means in Greek "to rain." The rain was believed to represent their tears of grief for their brother Hyas.
