    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.

Pollution's Effects on Us

The air is shared by everyone and everything on Earth. Living things breathe it and depend upon on it for life. When pollution is added to it, we can’t stop breathing or escape from it. After all, air is everywhere on Earth.

Unfortunately, breathing polluted air can harm one’s health. It can cause coughs, burning eyes, breathing problems, and even death in the most severe cases. Some pollution you can see. Have you ever seen a dirty sky? If so, you know it turns an ugly brownish or grayish shade and reduces visibility. It can even make city buildings or nearby mountains hard to see.

It is important to know that air pollution does not just harm humans. Just like people, wildlife and forests can become sick from air pollution. Our water and property made of stone or metal can be damaged by acid rain. This happens when pollution mixes with raindrops and makes them acidic as they fall to Earth.

Some people think that because we all share the air, no one will take care of it. This idea is called the "Tragedy of the Commons." A lot has been done to improve air quality in recent years, but we still have much to learn and do if we want to have cleaner and safer air.
