    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/.

Cygnus

Various Greek myths are connected with the constellation Cygnus, which means "swan." Some authors say that the constellation cygnus was related to the shape of a beautiful swan that Zeus assumed to court Leda, the wife of Tyndareus, the king of Sparta.
Others tell the story of Cycnus, the son of Apollo and Hyria. Cycnus was a very handsome young man. However, Cycnus was hard-hearted with those who loved him. He was so capricious that all his lovers and friends grew tired of his whims and abandoned him. Only Phylius remained loyal to him.
Cycnus ordered Phylius to perform several different tasks to demonstrate his love. First, Phylius had first to kill a lion without using an iron weapon. Then he had to capture (alive) ferocious man-eating birds. Finally, he had to lead a bull to the altar of Zeus with his own hands. Phylius succeeded in all these tasks with courage and love. However, Cycnus'requests went on and on. Phylius'patience was exhausted. He decided to stop indulging Cycnus and abandoned him. Cycnus, desperate, drowned himself in a lake, now called the Cycnean Lake. Following Cycnus'death, his mother Hyria threw herself into the same lake. Apollo then transformed his wife and son into swans, whose shapes can now be recognized among the stars.
