    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/.

Teacher Resources

Welcome to the Teacher Resources section of Windows to the Universe, where we try to collect resources of our own, as well as of partner organizations that we think you will be interested in. We regularly update this section with information about our web seminars, workshops and new classroom activities. We also provide links, below to several of our key resources, including motivational quotes, Earth science literacy frameworks, materials from our professional development workshops, our Teacher Opportunities calendar (Members Only), and a link to our free monthly Earth and Space Science Educator Newsletter. Windows to the Universe and its educational resources have been reviewed by NASA's Office of Space Sciences and Earth Science Enterprise, receiving exemplary status.

Teachers - Become an Educator Member of Windows to the Universe for special benefits and opportunities, including information about valuable special offers for classroom grants, professional development with travel and/or stipends, research grants, and more!

Windows to the Universe is now offering on-site professional development workshops for teachers. Find out more about this opportunity here. Information about our upcoming workshops and events at the NSTA conference in Indianapolis is available under 2012 on our Teacher Resources/Workshops page.
