    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.

The seven Rishis

According to the epic Mahabharata, composed after the Rig Veda in about 500 B.C., the stars of the Big Dipper were the seven sages called Rishis. These seven sages are said to be those who made the Sun rise and shine. They were happily married to seven sisters named Krttika. They originally all lived together in the northern sky.

But one day, the god of fire, Agni, emerged from the flames of a sacrificial offering performed by the seven Rishis and immediately fell in love with the seven Krttika. Trying to forget his hopeless love for the Krttika, Agni wandered in the forest where he met Svaha, the star Zeta Tauri. Svaha was at once infatuated with Agni.

To conquer Agni's love, Svaha disguised herself as six of the seven Krttika. For six times, Svaha made love to Agni who believed that he had conquered the attractive wives of the seven Rishis. Svaha could mimic only six of the Krttika because the seventh sister, Arundhati, was too devoted to her husband to be imitated. After a while, Svaha gave birth to a child that she named Skanda. With his birth, rumors began to spread that six of the Rishis' wives were his mother.

Six of the Rishis divorced their wives. Arundhati was the only one that remained with her husband as the star Alcor. The other six Krttika went away to become the Pleiades.
