    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.

Huygens Probe to Titan

A robot spaceship landed on the biggest moon of the planet Saturn in January 2005. The spaceship was named Huygens. Huygens landed on the moon Titan on January 14, 2005.

Huygens had been riding on the side of another spaceship for seven years. NASA's Cassini spacecraft carried Huygens to Saturn from Earth. Cassini "let go" of Huygens on December 24, 2004.

Huygens studied the atmosphere of Titan. Parachutes on Huygens lowered it through Titan's atmosphere. Then Huygens landed on Titan. The surface of Titan is very, very cold. The temperature there is about -178º C (-288º F)!

The spaceship was named after Christiaan Huygens. Christiaan Huygens was a Dutch astronomer. He discovered Titan in 1655.
