    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/.

Spring is no Picnic on Uranus
News story originally written on February 14, 2000

If you lived on Uranus, spring would probably not be your favorite season. Thanks to the Hubble Space Telescope, scientists can study the planet's climate like never before. They came up with some surprising results.

On Earth, spring is often considered a favorite season. The snow is melted, the grass is green and the temperatures warm up. On Uranus, spring signals a time of violent storms and cold temperatures. There are hurricanes larger than half of the United States, and temperatures dip below -300 ° F!

"No one has ever seen this view in the modern era of astronomy because of the long year of Uranus - more than 84 Earth years," Heidi Hammel of the Massachusetts Institute of Technology said in a statement.

Spring on Earth lasts for a few months. But on Uranus it won't be summer until the year 2007! This doesn't seem so bad when you compare it to the decades of winter the planet is leaving behind. Only one word comes to mind... Burr!
