    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.

Total Lunar Eclipse - November 2003
News story originally written on November 7, 2003

The second total lunar eclipse of 2003 will occur on the night of Saturday, November 8th. The Earth's shadow will darken the Moon for a total of more than four hours, while the "total eclipse phase" spans a period of about 25 minutes. If you live in the eastern part of North America, the middle of the eclipse occurs around 8:19 P.M. The eclipse begins before moonrise as seen on the West Coast, so the Moon will be tinted red as it rises in the West. The copper hue of the Moon during a lunar eclipse is caused by red light refracting through Earth's atmosphere which lights the Moon

Earth's shadow has two parts: a lighter outer ring, and an inner, darker circle. During a total lunar eclipse, the Moon passes through both sections of this shadow, so there are several different stages to the eclipse. The link to NASA's page about this eclipse (below) provides details about the times of the different stages for viewers in various locations.
