    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.

    EF-5 Tornado in El Reno, Oklahoma Widest Ever Recorded in US

    The EF-5 tornado that hit El Reno, Oklahoma on May 31st was the widest ever recorded in the US, according to the National Weather Service in Norman Oklahoma. The tornado, which remained on the ground for 40 minutes and reached 2.6 miles across (4.2 km), took the lives of 18 people including storm chasers Tim Samaras, Paul Samaras and Carl Young.

    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/.

Solar Eclipses Were not Always Enjoyed

Eclipses have been watched for centuries, but it was only recently that we understood what really occurs. Eclipses have always been fascinating to watch, but they weren't always welcome. For many years, civilizations around the world feared these rare occasions.

Ancient people were convinced a solar eclipse was a sign of something horrible. Some civilizations believed that the Sun was being eaten by some sort of animal, such as a dragon or wolf. They felt the only way to free the Sun was to act wild. So, the people would make noises called hullabaloos while dancing around and acting crazy. They continued this until the Sun was "free" from the animal.

Others believed an eclipse was a sign of disease and death. In South America, they believed a hidden Sun was the source of smallpox and the Spanish influenza. Some thought the Moon was evil, and chased after the Sun. In some stories, the Sun goddess was being chased by her brother, the Moon god. When he caught up with her, he would do evil things. People thought this meant evil things would happen on Earth.
