    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.

Chasing the Storm

The official "Hurricane Hunters" are the Air Force Reserve's 53rd Weather Reconnaissance Squadron. They fly through the eyes of hurricanes and record information. The information helps the National Hurricane Center meteorologists improve the forecasts by up to 30%. How does this happen?

For each mission, the Hurricane Hunters fly through the eye of a hurricane multiple times. They pin-point the center of the hurricane and whether the hurricane is strengthening or weakening. Also, instruments on the plane continually record the wind speed and direction. This information helps when forecasting the hurricane's track. The more accuate the forecast is, the less coastline will need to be evacuated. It costs about $1 million per mile to evacuate, so the information provided by the Hurricane Hunters is very valuable.

Another group which routinely flies into hurricanes is the Hurricane Research Division (HRD) of the Atlantic Oceanographic and Meterological Laboratory (AOML), which itself is part of the National Oceanic and Atmospheric Administration (NOAA). **whew** The HRD aircraft mainly focus on hurricane research, though some of the wind data collected is used to improve track forecasts.
