    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.

Saturn's Moons and Rings

The planet Saturn has a lot of moons. It has a total of moons!

Saturn also has huge rings which you can see in any picture of Saturn.

One of Saturn's moons is named Titan. Titan is a very big moon. Most moons don't have any air, but Titan does! The clouds on Titan are orange.

One of Saturn's moons looks like the "Death Star" from the Star Wars movies. It is called Mimas. Another moon has one white side and one black side. That odd moon is called Iapetus.

Some of Saturn's moons are medium-sized and some are very small. The names of the other medium-sized moons are Rhea, Dione, Tethys, Enceladus, Hyperion, Phoebe, Janus and Epimetheus.

Some old myths are about people and gods who have the same names as some of Saturn's moons.
