    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.

Tecamac, T1, March 24, 2006

What does Tecamac mean?

Measuring site T1 is in Tecámac. This is a little town close to Mexico City. The name Tecámac is a Náhuatl word, an ancient Mexico's language, spoken by Aztecs. In Náhuatl, Tetl or Tec means stone, camatl means mouth, and the c at the end means place, so Tecámac is "the place in the mouth of stone". A quite good name for this place because there is a lot of stones, dust, and Sun.

This town was founded by Aztecs many years ago, but there were people living there before them. Olmecs and people from Teotihuacan use to lived on Tecámac years ago, and the Aztecs, on their way to Mexico-Tenochtitlan, founded Tecámac in 1202.
