    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.

Atmospheric Science Literacy - Essential Principle 3

Atmospheric circulation transports matter and energy.

Fundamental Concept 3.1
Horizontal and vertical energy imbalances in the Earth System produced by unequal heating of Earth's surface create movement in the atmosphere and the ocean.

Fundamental Concept 3.2
Energy is exchanged within the atmosphere, as well as gained and lost across its interface with land and ocean through physical, geological, and biological processes organized in Earth System cycles (e.g. the water cycle). These exchanges help drive atmospheric circulations.

Fundamental Concept 3.3
Patterns of circulation in Earth's atmosphere can be observed at many different spatial scales from global to local. Temperature differences, the rotation of Earth on its axis, and the configuration of the continents and oceans establish the large-scale atmospheric circulation.

Fundamental Concept 3.4
Atmospheric transport of water affects the formation and development of clouds, precipitation, and weather systems, which are all important components of the global water cycle.

Fundamental Concept 3.5
Atmospheric circulations distribute matter and energy globally and establish weather and climate patterns.
