    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/.

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.

Leonardo da Vinci

Leonardo da Vinci was an Italian artist and scientist who lived between 1452-1519. Leonardo was the original Renaissance man, whose roles included inventor, engineer, architect, mathematician, geologist, and astronomer.

While he is best known as a painter, Leonardo primarily worked for the military, producing designs of tanks, airplanes, and submarines, hundreds of years before such war machines were created. He is also famous for his sketches of the muscles and bones in the human body.
