    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.

History and People

Who made the first star map? When did people know that the Earth was round? When were sunspots discovered? The links to the right will lead you to biographies of scientists who lived at different times through history. Discover the people who made science history!

<a href="/people/ancient_epoch/eratosthenes.html&dev=1">Eratosthenes</a> was a Greek scientist who lived from 276 to 194 B.C. He studied astronomy, geography, and math. Eratosthenes is famous for making the <a href="/the_universe/uts/eratosthenes_calc_earth_size.html&dev=1">first good measurement of the size of the Earth</a>. This portrait, drawn long after he was dead, shows what the artist thought he might have looked like.<p><small><em>Public domain.</em></small></p>Science educators on a research immersion experience with the <a href="/people/postcards/andrill/andrill_post.html&dev=1">Antarctic Geological Drilling Project (ANDRILL)</a> sent postcards to Windows to the Universe while they were in <a href="/earth/polar/antarctica.html&dev=1">Antarctica</a> from October 2007 until January 2008. The team drilled into <a href="/earth/geology/sed_intro.html&dev=1">sedimentary rocks</a> below the ice of the Ross <a href="/earth/polar/cryosphere_iceshelf1.html&dev=1">ice shelf</a> to help learn more about the environmental changes that have affected the continent in the past. This image shows what life is like in a field camp on the ice.<p><small><em>Image courtesy of Julia Dooley </em></small></p>Jocelyn Bell Burnell is a British <a href="/the_universe/uts/ast_history.html&dev=1">astronomer</a> who was born in 1943. She discovered <a href="/the_universe/NS.html&dev=1">pulsars</a> - <a href="/the_universe/Stars.html&dev=1">stars</a> which emit periodic radio waves - in 1967. Burnell was a graduate student at Cambridge University when she discovered pulsars. Her professor, Antony Hewish, received the Nobel Prize in Physics for her discovery.<p><small><em> The Open University</em></small></p><a href="/people/postcards/vocals/dione_rossiter.html&dev=1">Dione Rossiter</a> is a scientist that participated in a research expedition to understand the climate of the southeastern Pacific in fall, 2008 - the <a href="/vocals/vocals_intro.html&dev=1">VOCALS campaign</a>. She got to fly a her scientific instrument aboard a research aircraft above a layer of <a href="/earth/Atmosphere/clouds/stratocumulus.html&dev=1">stratocumulus</a> cloud that seemed to go on forever.<p><small><em>Image courtesy of Dione Rossiter</em></small></p>Although we humans have never experienced fast <a href="/earth/climate/climate.html&dev=1">global warming</a>, our planet has. And our planet keeps records of what happened. The oldest records that the <a href="/earth/earth.html&dev=1">Earth</a> keeps are in its <a href="/earth/geology/sed_intro.html&dev=1">rocks</a>. In this image, <a href="/headline_universe/olpa/methane_28may08.html&dev=1">geologists Chris von der Borch and Dave Mrofka</a> collect sediment samples in South Australia. These rocks hold clues to help explain why climate changed abruptly 635 million years ago.<p><small><em> Courtesy of Martin Kennedy, UCR</em></small></p>
