    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.

Cassini Titan Flyby in October 2004
News story originally written on October 28, 2004

The Cassini spaceship flew by Saturn's moon Titan on October 26, 2004. Titan is Saturn's largest moon, and has the thickest atmosphere of any moon in our Solar System.

Cassini took some great pictures of Titan during this flyby. Ten different instruments on Cassini made measurements of Titan. Cassini passed within 1,174 kilometers (730 miles) of the moon during this close encounter. Cassini, which is in orbit around Saturn, will fly past Titan 44 more times in the next four years!

Cassini will drop off a lander named Huygens. Huygens will touch down on Titan in January 2005. Some of the measurements of Titan's atmosphere that Cassini made on this flyby will help Huygens. The more scientists know about Titan's atmosphere, the safer they can make Huygens' entry into and flight through that atmosphere.
