    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 ISS is a Busy Place These Days!
News story originally written on June 13, 2002

The Expedition Four Crew has lived on the International Space Station (ISS) the longest of any crew, but now it is time for them to go home, making way for the Expedition Five Crew.(/p)

The Expedition Four Crew, Commander Yury Onufrienko and Flight Engineers Dan Bursch and Carl Walz, who have lived on the station since December 7, 2001, officially handed over their responsibilities to the Expedition Five Crew on Friday, June 7, 2002 soon after the new crew arrived at the ISS aboard the space shuttle Endeavour.

The new Expedition Five Crew, including Commander Valery Korzun and Flight Engineers Peggy Wilson and Sergei Treschev, will have a busy four-month stay at the ISS. During their stay, the station will be visited by four spacecrafts and the crew plans to do two space walks. Also, they will collect data for 24 new and continuing scientific experiments.

Endeavour launched June 5, 2002 carrying the new crew for the ISS, a new base for the station's robotic arm and almost 3 tons of experiments and supplies. Endeavour's crew includes Commander Ken Cockrell, Pilot Paul Lockhart and two Mission Specialists named Franklin Chang-Diaz and Philippe Perrin.

Besides replacing the ISS crew and providing new supplies and experiments, Endeavour's Mission Specialists are working with the ISS crew this week to make repairs and improvements to the station's robotic arm. The arm helps build and maintain the station. Hopefully, when they are through with their three space walks, the arm will be able to move the length of the station on a track that works like a railroad track. Being able to move along the track will allow the arm to reach easily all parts of the station.

Endeavour will return the Expedition Four Crew to Earth later this week, landing at Kennedy Space Center in Florida.
