    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.

Face-Off!
News story originally written on April 8, 1998

The camera aboard the Mars Global Surveyor (MGS) has imaged an area of the Cydonia Region of Mars. It was here that the 'Face on Mars' was first photographed by the 1976 Viking mission.

In the 20 years since the 'Face' was photographed, most scientists have held to the view that the image of the 'Face' was just a trick of light and shadow upon natural geological features. However, there were many believers of extraterrestial life who thought the image was showing what could have been part of an ancient city on Mars...shaped like a face to attract exploration of that area.

The range of the MGS image was taken at 444.21 kilometers whereas the Viking image was taken at a range of 1873 kilometers. That means that the more recent MGS image is more accurate. As one can see from the new MGS photo on the left, the 'Face' is more likely just a geological feature. "It's a butte, a mesa, a knob," said Michael Ravine, advanced projects manager at Malin Space Science Systems in San Diego, which operates Surveyor's camera. "Nothing jumps out at me and screams, 'This must have been built by the forces of intelligence'."

Because of the controversy involved about the 'Face on Mars', NASA has offered no opinion. Though it seems this two-decade face-off is coming to a close as the MGS has provided images of only geological features...
