    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.

Finally! Two years of frustration and disappointment was overshadowed by the docking of Russia's Zvezda module to the International Space Station. The module was flying alone for two weeks while being tested. At speeds over 17,000 miles per hour, Zvezda joined with the other two pieces of the station.

Scientists around the world applauded as the biggest hurdle yet faced by the ISS was over. The Zvezda module is 43 feet long. It will serve as the sleeping and dining area for the crew, the main power source for the station, as well as a small laboratory. The first crew will visit the ISS in November.

"The International Space Station has nearly doubled in size in just a few moments," NASA spokesman Rob Navias added from Houston.

Zvezda joins the U.S. Unity and the Russian Zarya in space. Zarya was the temporary power source and will now serve as a passageway. The Unity is the docking port for future missions. The main laboratory will be launched in January.
