    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 approaches Saturn's Moon Phoebe
News story originally written on June 11, 2004

The Cassini spacecraft, en route to Saturn, will zoom past Saturn's odd moon Phoebe on June 11, 2004. Cassini will pass within 2,000 km (1,243 miles) of the moon's surface and should send back images with a resolution of 0.3 to 2.1 km (0.2 to 1.3 miles) per pixel. Those should be about 1,000 times better than our best current images of Phoebe, which were captured by Voyager 2 in September 1981.

A few weeks later, Cassini will end its long journey to Saturn, begun in October 1997 with its liftoff from Florida. On July 1, 2004, Cassini will fire its main engine for 96 minutes to slow itself down and go into orbit around Saturn. It will study Saturn, several of its moons, and its amazing ring system for the next four years.
