    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/.

Oh No, Not Again!
News story originally written on December 9, 1999

It appears that disaster has struck yet again. The Mars Polar Lander, which landed on the Red Planet on December 3, 1999, has yet to regain contact with Earth. Scientists have watched six chances for contact pass by, leaving many to believe the spacecraft was lost.

Another failed mission will put NASA under more scrutiny. The program lost the Mars Climate Orbiter in September because of a math error. The estimated cost of the Polar Lander program is $165 million, which is actually cheap in terms of space projects. The Climate Orbiter is part of the new line of cheaper, faster, better spacecraft. But now it seems that NASA may be ahead of its time.

To make matter worse, the two probes aboard the Lander have also failed to contact Earth. Scientists say that even if the probes were working, they would no longer be sending signals because the batteries should be dead. The probes were supposed to crash into Mars and burrow into the ground to look for water.
