    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.

Heracles (Hercules)

According to the Greek mythology, a particular group of stars represents the figure of the most famous Greek hero, Heracles. Heracles was a muscular man endowed with extraordinary courage and physical strength. The ancient Romans called him Hercules.

Heracles was the son of the sky god Zeus and the queen of Tiryns, Alcmene. When Hera discovered Zeus' infidelity, she decided to kill the child born from the Zeus' relationship with Alcmene. That child was Heracles. Hera placed two serpents in Heracles' cradle, but the child strangled the snakes with his bare hands, clearly revealing his divine nature. This and many other heroics made Heracles famous throughout the ancient world.

Hera was so annoyed at Heracles' growing fame that she cast a spell of madness over him. Out of control, Heracles killed his own wife and children. His remorse was so profound that when he returned to his senses he could find no peace of mind. He visited the oracle of Delphi to see how he could demonstrate his remorse.

The oracle advised him to obey the orders of Eurystheus, the king of Tiryns and Mycenae. Eurystheus ordered Heracles to accomplish twelve difficult tasks (the so-called Twelve Labors of Heracles). Heracles completed the twelve labors and is celebrated to this day for his great courage and strength.
