    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/.

Boarding U.S. Airforce C-17 Globemaster III

Finally the fax arrived that weather conditions in Antarctica had improved dramatically, and our flight was scheduled for noon on October 10. On that day, we hurried to the CDC, donned our Extreme Cold Weather (ECW) clothing, exchanged our departure cards for boarding passes, went through intense security screening, and boarded the U.S. Airforce Boeing C-17 Globemaster III, an awesome aircraft.

The C-17 can take up to 170,900 pounds of cargo, and when I walked into the plane, I felt like I had been swallowed by a whale. All the internal organs of the plane were visible: pipes, wires, insulation, valves, cargo clips, hoses, and electrical outlets. People were dwarfed by this enormous internal structure and the immense amount of Antarctic cargo it was carrying. We appeared to look like Big Red plankton swimming inside the rib cage of some gigantic animal.

Under "Operation Deep Freeze", the U.S. military provides peaceful support for the missions of the U.S. Antarctic Program. The C-17 was designed for rapid airlift of troops and cargo, and what that meant for us is that we would arrive in Antarctica, weather permitting, within five hours instead of the usual seven hours by Hercules C-130 aircraft. But, for us, it would a few hours longer as the crew had to adjust the brakes in one of the engines, as you can see in the postcard, allowing us a rare opportunity to check out a marvel of mechanical engineering. All the while we kept wondering if the weather would turn bad again in Antarctica.
