    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/.

Life Found on the ISS
News story originally written on November 20, 2000

Man has always been compelled to explore and inhabit previously unknown realms. As of this month, man is again inhabiting the daunting expanse we call space. Eight years after the initial agreement to pursue development of the International Space Station (ISS), three men made the ISS their home on November 2, 2000. For the next four months, Russian astronauts Yuri P. Gidzenko and Sergei K. Krikalev and American commander, William M. Shepherd, will call the ISS their home.

The building and inhabitation of the station has been an extremely long journey already fraught with many setbacks, delays, funding and political issues. It is with relief that the space agencies can say the station is finally inhabited. It is their hope that the station will remain inhabited continuously for at least the next 15 years. Upon arriving at the station Shepherd, a Navy officer on his fourth mission to space, commented, "We're just starting a long journey." Appropriately, the ISS has been officially named Alpha. Alpha is the first letter of the Greek alphabet and so denotes "a new beginning". It is also a neutral name in that it is neither English nor Russian.

The Alpha station is now the size of three school buses in length. In time, Gary Kitmacher, space and life sciences manager for the International Space Station manned operations at Johnson Space Center says, “it will be the size of a Boeing 747 and the length of a football field.” He also adds it will become the brightest object in the night sky next to the Sun and the Moon.

Shuttle Endeavour will dock with the space station December 2, 2000. This shuttle mission will bring supplies to the space station as well as the very important P6 Truss which will increase the ISS's power capability with its solar arrays. A new crew will come to live on Alpha in February.

NASA and the Russian space agency and the other 16 countries contributing to the building of the ISS hope that this station will open the door to long-term living on the Moon and Mars.
