    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.

    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

Huygens probe on its way to Titan
News story originally written on December 30, 2004

NASA's Cassini spacecraft is in orbit around the planet Saturn. Cassini carried a landing probe, named Huygens, with it on its long journey from Earth. On December 24, 2004, Cassini released the Huygens probe. Huygens will land on Saturn's largest moon, Titan, on January 14, 2005.

The Huygens probe will take 2-1/2 hours to descend through Titan's thick atmosphere on parachutes. It will make measurements of the moon's atmosphere as it descends. Nobody knows what the surface of Titan is like. It may be solid, or it might have lakes or seas of liquid ethane or methane. It might even be covered by a thick layer of methane snow. Huygens may land with a bump, a splash, or a puff!

The probe was built by the European Space Agency. It is named after Christiaan Huygens, a Dutch astronomer who lived in the 17th century. If it survives the landing, the Huygens probe may send back data from the icy surface of Titan for up to 30 minutes after it touches down. The Cassini spacecraft will continue to orbit Saturn, studying its moons and rings, for at least four years. Let's hope that Huygens has a safe landing and sends us good pictures of the surface of a world that nobody has ever seen before!
