    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.

Venus Transit in June 2004
News story originally written on June 2, 2004

Sometimes planets go in between Earth and the Sun. When that happens astronomers call it a "transit". On June 8, 2004, the planet Venus will move between Earth and the Sun. There will be a transit of Venus!

A transit is a bit like an eclipse of the Sun. There hasn't been a transit of Venus in more than 100 years! The last one was in the year 1882.

Remember, it is never safe to look directly at the Sun. This NASA web site tells you how to safely watch the transit. It also has lots of good info about Venus transits.
