    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 scientific results of the VOCALS field campaign are based on analysis of observations made by instruments located on ships, aircraft, and land. This map shows the paths followed by ships and planes over the Southeast Pacific and the observation stations along the coasts of Chile and Peru.

What are the results of VOCALS?

Scientists must work very hard to understand the data collected in field campaigns like VOCALS. They must review and study it to determine what has been learned. Many model runs will be made and analyzed. Eventually, they will publish their discoveries in scientific journals and give oral presentations at conferences.

VOCALS will allow examination over an entire month of how variability in ocean currents, ocean upwelling, marine winds, and air pollution will impact the properties of the atmosphere, the clouds, and the amount of precipitation found there. The climate of the Southeast Pacific is especially complicated by the nearby Andes Mountain range.

VOCAL measurements will be important! They will add to current knowledge in the fields of atmospheric science and oceanography. They will be used to improve models exploring the atmosphere and climate. VOCALS could ultimately lead to much better predictions of future climate. Predictions are very important to people around the world who are in danger from the impacts of climate change, such as sea level rise, heat waves, drought, severe rainstorms, and changes in growing seasons.
