    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.

Cassiopeia

The constellation of Cassiopeia is one of the most famous in the sky. It is very easy to identify the stars that are part of it because they have the shape of a W.
Cassiopeia was the daughter of Arabus, a son of Hermes, who gave his name to the country named Arabia. Cassiopeia was also the ostentatious wife of Cepheus, the king of Ethiopia.

She was so proud of her beauty that once she declared that she and her daughter Andromeda were more beautiful than the sea nymphs, the Nereids. Offended, the nymphs complained to the sea god Poseidon, who avenged Cassiopeia's offense by sending a sea monster and a flood to destroy Cassiopeia's land. In despair, the king consulted the oracle of Ammon about how to prevent the destruction of his kingdom.

The oracle predicted that only the sacrifice of the king's daughter to the monster could appease Poseidon's wrath. Andromeda was chained naked to a sea cliff. Fortunately, at this same moment, Perseus , the nephew of the king of Argos, was traveling along the coast. Perseus noticed the beautiful Andromeda chained to a cliff and immediately fell in love with her.

Nearby, Andromeda's parents waited, resigned to their daughter's fate. Perseus approached them and learned of the impending peril. He promised to save Andromeda and marry her. Perseus'courage prevailed against the monster, and the marriage could finally be celebrated. It is said that the sea god Poseidon placed the figure of Cassiopeia among the stars to remind people of her vanity.
