    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.

Gaea

Gaea, or Mother Earth, was the great goddess of the early Greeks. She represented the Earth and was worshipped as the universal mother. In Greek mythology, she created the universe and gave birth to both the first race of gods (the Titans) and the first humans. Her husband was Uranus, the god of the sky. She presided over marriages and oaths and was honoured as a prophetess.
