    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/.

Ganymede

Ganymede was a son of Tros, who was the ruler of the city of Troy. One day, Jupiter saw Ganymede as he tended sheep on the slopes of Mount Ida, and suddenly had a strong desire to make the young man the servant of the gods at Olympus. Jupiter changed his shape into that of an eagle, swooped down onto the slopes of Ida, and carried the boy off to Mount Olympus, home of the gods, to serve as the cup bearer of the gods. Now it so happens that this position was already filled by Hebe,the daughter of Jupiter and his wife Juno. Once Ganymede arrived at the royal court Hebe and Ganymede competed with each other for the honor of serving the gods. Eventually Ganymede won the post, and he also became Jupiter's favorite companion. To honor the events surrounding Ganymede becoming the new cup bearer and servant of the gods, Jupiter placed the eagle, a shape he assumed when carrying Ganymede to Olympus, into the heavens as the constellation Aquila (eagle), and then immortalized Ganymede by placing him in the heavens as the constellation Aquarius (water bearer).
