    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/.

Not Just a Guy in a White Coat
News story originally written on February 26, 2009

Can you tell the difference between anecdotes and tested ideas? Do you know what science is and what it is not?  To make sense of the world today, it’s important to understand science.

You may have heard that scientists follow a defined process called the scientific method when they go to tackle a problem: Ask a question, form a hypothesis, conduct an experiment, collect data and draw a conclusion. But science is much more than those steps. It’s dynamic and creative. That’s what a new Web site called Understanding Science seeks to explain.

Instead of the five-step scientific method, there is an interactive chart showing how science works: the many motivations leading to exploration and discovery; the ways that ideas are tested out; the role of teamwork, analysis and feedback; and possible benefits and outcomes that result from making science happen.

The Web site illustrates what science is and how it works using real-life examples--from the structure of DNA to advances in fueling technology to the discovery of insulin. The site even offers a chance to consider whether pursuits like astrology are, or are not, science.

Understanding Science is designed for the general public and educators. Links to teacher resources include resources targeted to primary, middle school, high school and undergraduate-level educators.
