    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/.

Hubble Servicing Mission Canceled
News story originally written on April 21, 2004

NASA announced in January 2004 that it would cancel the last planned mission to the Hubble Space Telescope (HST). The head of NASA, Sean O'Keefe, believes a mission to Hubble would be too dangerous for the Space Shuttle. NASA is being very careful about Space Shuttle missions since the Columbia disaster.

NASA had planned to fly a Shuttle to Hubble sometime in 2006. During that mission astronauts were to replace several pieces of Hubble that are wearing out. They were also going to add in some new, more powerful instruments.

In a few years Hubble will begin to fail. Its batteries might wear out or its gyroscopes, which steer the telescope, may stop working. NASA plans to attach a rocket to Hubble in a few years and steer it towards Earth. Hubble will partly burn up in the atmosphere. The rest of Hubble will crash into an ocean far away from where people live.

NASA is making a new space telescope to replace Hubble. The new telescope is called the James Webb Space Telescope. Its mirror has an area six times as large as Hubble's mirror. The new telescope is supposed to be launched in 2011.

Some people think it is a mistake to cancel the mission to Hubble. They think it is safe enough to send astronauts to fix the telescope. Other people disagree and think it is too dangerous. NASA, President Bush, and the U.S. Congress are debating the issue.
