    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/.

    Massive Tornado Outbreak on Tornado Alley

    The week of May 19 brings dozens of tornadoes to Tornado Alley in the states of Oklahoma, Kansas, Iowa, Illinois and Missouri. On May 20th, a massive tornado struck Moore, Oklahoma, devastating communities - destroying over 100 homes and hitting two elementary schools and a hospital - with many casualties and deaths. Our thoughts are with our friends and colleagues suffering from these storms. For more on the May 20th storms, see the NOAA Storm Prediction Center Storm Report.

    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

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.
