    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.

Jupiter Clouds, overview

Jupiter's appearance shows a striped pattern of clouds of white, brown, and orange, and the Great Red Spot. The Great Red Spot is the largest of the cloud patterns on Jupiter. Other cloud shapes include eddy shapes, white ovals, brown ovals, and brown barges. The eddies and white ovals are outlined in this picture, when shown at full size.

These clouds form in bands which move across the disk of Jupiter. The banded pattern of clouds, or stripes, is similar to those found on all the giant planets.

There are three clouddecks on Jupiter, and each one is composed of different molecules. There is a clouddeck of ammonia clouds, a clouddeck of ammonia hydrosulfide clouds, and a clouddeck of water clouds (H2O). These clouds are found in the troposphere of Jupiter.

Hazes of smog on Jupiter are to be found at very high altitudes above the clouds of Jupiter.
