    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.

Northeaster in Action

This radar image shows a northeaster that moved through the east coast of the United States on April 15-17, 2007. Several areas in the Mid-Atlantic and northeast regions were flooded because of heavy rain that fell along with strong winds. 7.6 inches (1.92 meters) of rain fell in New York City on April 15th from this northeaster. Accumulations of as much as 17 inches (43 cm) of snow fell in high elevation areas of northern New York, Vermont, and New Hampshire. This animation helps demonstrate how a northeaster builds in intensity. As the storm moves from the Atlantic Ocean onto land then to the areas of higher elevation, you can see the strong spin of the storm and the change in color from blue to yellow. A northeaster starts to weaken when it moves onto the higher terrain. The blue color represents clouds that are closer to the ground while the yellow color is colder clouds higher in the atmosphere. This northeaster affected the runners of the Boston Marathon. Strong winds also caused power outages from South Carolina to Maine.

Type of Wind: Northeaster

Northeasters, also known as nor’easters, are cyclonic, cold winds that develop in the mid-latitudes. They can bring heavy snow or sleet and gale force winds of 40-55 mph (64.5-88.7 kph). This type of wind...more
