    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/.

The Skywatchers of the Americas

Early man would not have been distracted by t.v., video games, city lights or any of the things that keep us from spending our nights looking up at the black, starry sky. Long before farming, man would have watched the cycle of the Sun because that cycle told them when plants would be ready for picking and when animals would be around to be hunted. And so we see that even the earliest man would have watched the day and night sky.

Humans first lived in present-day Africa and the Middle East. These early hunter-gatherers roamed through Europe and Asia. It is thought that from Asia, people crossed the Bering Strait into North America while the straight was frozen over. There is so much evidence to support this theory that many people accept it as the way that the Americas came to be populated by humans. By 30,000 B.C., people were present in the Yukon. These hunter-gatherers just kept roaming the land perhaps following animals or water sources so that by 12,000 years ago, people were as far south as Argentina!

It is these people who were the Natives of the Americas. They too watched the sky. It is interesting to look at evidence of that skywatching by looking at the ancient astronomy practiced by the Native Americans of North America, the Maya of Central America and the Inca of South America.
