    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.

Results from Mars Pathfinder

These are the findings of Mars Pathfinder.

  • High Silica Rocks - a result from chemical analysis of the Martian rocks.
    • suggestive of differentiated (evolved) rocks and minerals.
    • helps establish that, like Earth, Mars experienced mineral separation, evolution, and differentiation of the silica rocks (the same rocks which are important to terrestrial planet formation).
  • Rounded Pebbles, Cobbles and possible Conglomerates were found - a result from analysis of the landingsite, the rocks, the soils, and erosion patterns.
    • suggestive of fluvial processes over a long time
    • suggestive of liquid water in equilibrium with the atmosphere
    • suggestive of a warmer & wetter Martian past
  • Airborne Dust is Magnetic
    • chemical analysis of the dust shows that iron seems to be leached from the crust by an active hydrologic process
  • Better Moment of Inertia measurement (the shape of Mars)
    • suggests Mars has a large core
  • Landing site is as expected
    • validates the use of ground-based measurements
    • showed a variety of rocks deposited by a catastrophic flood
    • questions remain about the deposition conditions, variety, and origin of the rocks
    • other remaining questions include: how fast, & where was the Martian water flowing, what was the capacity of the flood?
  • Atmosphere
    • water ice clouds were found
    • dust devils
    • predictable local weather
These findings help address questions which remain about Mars.
