    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.

Estsanatlehi

According to Navajo Native Americans, Estsanatlehi, whose name means "Changing Woman", created the first man and woman from pieces of her own skin. She is the wife of the Sun god, Tsohanoai and the mother of the two Navajo heroes, the twins Nayenezgani and Tobadzistsini.

Her home is on an island far to the west where Tsohanoai meets her every evening as he sets. She is said to become old each winter and to rejuvenate each spring. This curious peculiarity is related to the changing of the seasons.

It is believed that Estsanatlehi eventually became the goddess of the underworld.
