    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.

Ice Storm Image Gallery

This gallery is a collection of images from the ice storm that struck Norman, OK on December 9-10, 2007. The ice was formed by freezing rain. Roadways were very icy, which caused accidents. The storm caused damage to trees and power lines. Over a million people lost electrical power. Several of the images were taken at the campus of the University of Oklahoma.

This is a wind vane. When it is not covered with ice, its cups spin to measure wind speed and direction. The cups were covered in ice from the freezing rain.

The leaves in this image froze in the direction the wind blew. Ice that is beyond the leaves is from the wind and the collection of the freezing rain.
