    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.
The Sun on March 30, 2001. You can see the huge sunspot in the upper, right hand part of the Sun. Though it doesn't look like much, this area is equivalent to the surface area of 14 Earths! The sunspot has since moved so that it is on the far side of the Sun from Earth.

Massive Sunspot! (Updated!)
News story originally written on April 4, 2001

The largest sunspot of the decade has shown its face on the Sun. Another flare has shot from this sunspot! It was released at 4:51 EDT, Monday.

Because the Sun rotates, this massive sunspot moved across the Sun in the last week to the far side of the Sun as viewed from Earth. That means the flare's resulting coronal mass ejection (CME) won't hit the Earth directly. But this flare is so huge (an X-20 classification), that it will affect the Earth. This means there may be increased auroral activity which could possibly be viewed the nights of April 4th and 5th.

Dr. Paal Brekke, the European Space Agency Deputy Project Scientist for the Solar and Heliospheric Observatory (SOHO), one of a fleet of spacecraft monitoring solar activity and its effects on the Earth, said this flare, "was more powerful that the famous March 6, 1989 flare which was related to the disruption of the power grids in Canada." So, if the sunspot hadn't moved across the Sun in the last week, this solar event could have struck Earth with its full force. Then there could've been serious radio disruptions or power blackouts!
