    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/.

Final Flight of Space Shuttle Atlantis

The space shuttle Atlantis finished its last flight when it landed on May 26, 2010. NASA is retiring the whole fleet of space shuttle orbiters by the end of 2010. Discovery and Endeavor are the other two working space shuttles.

Atlantis blasted off on its last mission on May 5, 2010. The shuttle carried a new Russian-built research module to the International Space Station (ISS). Astronauts went on three spacewalks during the shuttle's mission.

The first flight of Atlantis was in October 1985. This orbiter has flown 32 missions. Atlantis flew the final mission to the Hubble Space Telescope in May 2009. This shuttle also flew seven missions to the Russian Mir space station and many flights to the ISS. Atlantis also launched the Magellan and Galileo space probes in 1989.
