    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/.

Eduardo A. Araujo-Pradere

I joined Windows to the Universe in 2003. My main roles are answering Ask-a-Scientist questions and confirming the scientific validity of the content after it is translated into Spanish.

I was born and raised in Havana, Cuba. My first interests were biological sciences, because I wanted to be a medical doctor like my parents, but later, as a young adult, I was fascinated by the way Physics could explain everyday phenomena. My focus then switched to Physics and science in general.

My professional background is in space sciences, education, and electronic engineering. I received my bachelor degrees in my country, Cuba, my Master's in space studies from the National Autonomous University of Mexico (UNAM), and my Ph.D. in space physics also from UNAM, while doing my research at the University of Colorado. My work as a scientist involves the study and modeling of the Earth's ionosphere, especially during perturbed conditions, when the Sun is acting funny and our planet, under the right conditions, receives part of the energy released during these active periods. I currently work as a Scientist Research with the Cooperative Institute for Environmental Research of the University of Colorado (CIRES-CU), and am affiliated with the Space Environment Center of the National Oceanic and Atmospheric Administration (SEC-NOAA).

I am also passionate about education and outreach, having accumulated over 20 year of Physics teaching in several countries and in different languages. I have also written several outreach articles in Spanish language newspapers. My role in Windows to the Universe gives me the opportunity to help to produce a great product in my primary language, an asset for the Spanish speaking population in America and the world.

I love being with my children David, Victor and Elsa , and with my wife Alma. Reading, swimming and scuba diving are my favorite activities.
