    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.

I studied Chemical Engineering at the National Autonomous University of Mexico. After that, I realized that fluids flowing in a pipe was not as interesting as studying bigger things, like oceans, mountains, clouds, and the Earth itself.

So I studied then Earth Sciences at the same University. During my master degree I focused on carbon particles in the atmosphere, where do they come from, what are they doing, are they watching us? Too many questions and just a few answers. So, I began my doctorate studies to study the flying part of particles, that is the organic composition.

MILAGRO project is important to the people in Mexico City, if we want to play soccer and see the ball in clear days with no particles and no health damages, we have to learn how to eliminate them from the air. During this project I'm going to be on the guided visits to the research sites and reporting from the field any news from scientists and the atmosphere.
