    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.

Florence Bascom

Florence Bascom was one of the first female geologists in the United States and her fellow scientists thought she was one of the nation’s most important geologists. She lived from 1862 until 1945 and is well known for her work at Bryn Mawr College where she taught for many years.

Bascom studied mineral crystals by looking at them with a microscope. She also studied metamorphic rocks, how mountains form, and how rocks from mountain erode into sand. At the time she went to college, it wasn’t easy for a woman to go to study for advanced degrees in the United States. But that didn’t stop Florence Bascom! She earned two bachelor’s degrees and a master’s degree from the University of Wisconsin and a Ph.D. in geology from Johns Hopkins University. She was the second woman to ever earn a Ph.D. in geology in the United States.

Florence started teaching geology at Bryn Mawr, a women’s college, in 1895. She collected minerals, rocks, and fossils for the college and taught hundreds of students over the years, many of whom became successful geologists too!
