    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/.

I am a planetary scientist who has studied the Sun, Mercury, Venus, Earth, Moon, Mars, asteroids, meteorites, the satellites of Jupiter and Saturn, and comets. Sometimes I feel the solar system is too small for me. But then I look out the window or thru a telescope and realize that I really don't understand much.

Like many scientists I became interested in science as a young person when I observed an eclipse of the Moon. I read science fiction and followed closely the American space program.  As a college student I earned degrees in astronomy, geophysics and planetary science, along the way starting to give talks to students about the Moon and volcanoes, my two favorite topics in the universe. I interrupted formal education twice to teach in the Peace Corps in Kenya and then later to conduct geologic research in Ethiopia - both were tremendous learning experiences.  I spent a year hitch-hiking through Africa, the near east and Europe, and recommend it to everyone.  I have written dozens of research papers, presented hundreds of professional talks, written four books and a monthly column for Sky and Telescope magazine since 1999. I blog nightly for the Lunar Photo of the Day website and maintain the Moon Wiki website which is the largest single source of information about lunar craters, mountains and lava flows.

For the last two decades I have led educational technology programs to infuse learning with the instant access to knowledge and real data that is transforming science. School is boring, so how can we make it more like scientific research. How can we capture the minds of students with exciting challenges of understanding important things? That is what education should be about. That and exploring the world.
