    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/.

Myths about Moon

Many cultures around the world have interesting myths about the Moon, reflecting its prominence in the night sky and its impact on our lives. Visit the links below for interesting glimpses into the beliefs of early civilizations. Do you see any similarities between these myths?
The Full Moon in January is called the Wolf Moon. It is named after the hungry packs of wolves that howled at night.  The Algonquian tribes of Native Americans had <a href="/earth/moon/full_moon_names.html">many different names</a> for the Full Moon through the year, reflecting their connection with nature and the <a href="/the_universe/uts/seasons1.html">seasons</a>, hunting, fishing, and farming.<p><small><em>Image courtesy of Windows to the Universe</em></small></p>In ancient times, Chinese people believed that there were twelve Moons as there were twelve months in one year. It was believed that the Moons were made of water. The name "mother of moons" is associated with that of <a href="/mythology/moon_china.html">Heng-o</a>.
