    Irish Chronicles Document Links Between Volcanoes and Weather

    A study of over 40,000 written entries in Irish Annals and ice core measurements shows a strong correlation between the occurrence of volcanic eruptions and extreme cold weather in Ireland over a 1200 year period. Data analyzed in this study cover the period from 431 to 1649, during which time up to 48 volcanic eruptions are identified in Greenland ice core records through deposition of volcanic sulfate in annual layers of ice. You can find the study (open access), published on 6 June 2013 in IOP Publishing's journal Environmental Research Letters, at http://iopscience.iop.org/1748-9326/8/2/024035/article.

    EF-5 Tornado in El Reno, Oklahoma Widest Ever Recorded in US

    The EF-5 tornado that hit El Reno, Oklahoma on May 31st was the widest ever recorded in the US, according to the National Weather Service in Norman Oklahoma. The tornado, which remained on the ground for 40 minutes and reached 2.6 miles across (4.2 km), took the lives of 18 people including storm chasers Tim Samaras, Paul Samaras and Carl Young.

    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/.

The Stardust spacecraft came back to Earth in January 2006. The main spacecraft let go of the sample return capsule. The capsule re-entered Earth's atmosphere. It then used parachutes to gently land in Utah. Scientists in a helicopter picked up the capsule.

Stardust returns - with comet dust!
News story originally written on January 11, 2006

A spacecraft is coming back to Earth after a long mission. The spacecraft is named Stardust. Stardust went on a journey to a comet. The trip lasted 7 years!

Stardust grabbed some pieces of dust from the comet it flew by. It is bringing that dust back to Earth. Scientists will study the dust to learn more about comets. Stardust flew by a comet named Wild 2. It took some really great pictures of the comet.

Stardust put the dust it grabbed into a capsule. The capsule will land on Earth on January 15, 2006. It will land in the desert in Utah. Scientists will get the dust from the capsule so they can study it. Nobody has ever been to a comet. This is the first time stuff from a comet has been brought back to Earth. Scientists are excited to get their first chance to look at comet "stuff" up close. They think they will learn a lot about comets from the dust!
