    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.

Living Things Affect Climate

There are many different ways that the plants, animals, and other living things affect climate. Some produce greenhouses gases that trap heat and aid global warming through the greenhouse effect. Others take greenhouse gases out of the air. Here are some examples:

  • Plants take greenhouse gases out of the air. During the night, plants release some back into the air. They take much more greenhouse gas out of the atmosphere than they put in.
  • Farm animals like cows and sheep make greenhouse gases when they digest their food.
  • Wetlands and rice patties and the tiny, microscopic bacteria that live there make greenhouse gas.
  • Factories and power plants release greenhouse gas into the atmosphere when fossil fuels are burned.
  • Cars and trucks release greenhouse gas when they burn fossil fuels.
  • We use fertilizers to help plants grow but they also make greenhouse gas when they break apart in the soil.
  • Wildfires put greenhouse gas into the atmosphere as they burn. But if the forest grows back, it will take greenhouse gas out of the atmosphere.

Humans control many things that produce greenhouse gases. Today, more greenhouse gases are put into the atmosphere than are taken out. This is causing out planet to become warmer because of the greenhouse effect.
