    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.

CONTOUR on its Way to Catch a Comet!
News story originally written on July 3, 2002

NASA’s Comet Nucleus Tour (called CONTOUR) launched July 3, 2002. The CONTOUR spacecraft will fly by at least two comets. It will take pictures and collect dust from the nucleus of each comet. Learning more about comets will help scientists answer some big questions!

One of these big questions is what the solar system was like when it was very young. Comets formed when our solar system formed. Because they are very old, they may tell us what changes were going on when the solar system formed.

Another big question is how Earth first became a good place for life a long time ago. Comets may have helped! When they showered over the Earth long ago, they may have brought things, like water and carbon, which helped life evolve and grow. If we know more about what comets are made of, we can know if this might be true.

To answer these big questions, the CONTOUR spacecraft will record data from at least two comets. It will encounter Encke in November 2003, and the Schwassmann-Wachmann 3 comet in June 2006.
