Science Cafe Raleigh – Geological Forces in North Carolina

Our May Science Café (description below) will be held on Tuesday 5/18 at Tir Na Nog on S. Blount Street. This year there has been an incredible amount of geologic activity around the world. During this cafe we will be talking about volcanoes and earthquakes and how these and other forces have shaped North Carolina. Our café speaker for the evening will be Dr. Kevin Stewart from the Geology Department at UNC. It should be an interesting evening for all of us to learn more about the earth, how it changes, and how those changes can affect our present world. Dr. Stewart will have some of his books on hand for those who may be interested in getting a copy.
Geologic Forces in Our State and Beyond
Tuesday, May 18, 2010
6:30-8:30 p.m. with discussion beginning at 7:00 followed by Q&A
Tir Na Nog 218 South Blount Street, Raleigh, 833-7795
Earthquakes, volcanic eruptions, tsunamis, rising seas! These geologic events have been making the headlines lately, but did you know these same events have shaped the North Carolina landscape for the past billion years? We tend to think of our state as being far from the geologic action, but we once had Himalayan-scale mountain ranges and exploding volcanoes. Join us as we discuss the geologic history of North Carolina as well as the global geologic events that are occurring today.
About the Speaker:
Dr. Kevin Stewart has been a professor of Geological Sciences at UNC-Chapel Hill for the past 24 years. Stewart’s research focuses on the deformation of the earth’s crust and the tectonic history of mountain belts. He has worked in the southern Appalachians, the Rocky Mountains, and the Apennines in Italy. He recently co-authored a book published by UNC Press titled Exploring the Geology of the Carolinas.
Please RSVP (katey.ahmann@ncdenr.gov) if you are able to come. Tir Na Nog’s owner will be there that night to help make sure all goes well.

Science Cafe Raleigh: Clash of the Titans; Energy, Environment, and the Economy

Our April Science Café (description below) will be held on Tuesday 4/20 at the Irregardless Cafe on Morgan Street. Our café speaker for that night is Rogelio Sullivan, Associate Director of the Advanced Transportation Energy Center and also of the Future Renewable Electric Energy Delivery and Management Systems Center (FREEDM) at NCSU. Come and learn how our country is dealing with our ever-increasing energy consumption, and of ways that we may be able to reduce our dependence on foreign oil using a combination of innovative alternative energy cars and changes in our daily transportation habits.
Clash of the Titans; Energy, Environment, and the Economy
Tuesday, April 20, 2010
Time: 6:30 – 8:30 pm with discussions beginning at 7:00 followed by Q&A
Location: The Irregardless Café, 901 W. Morgan Street, Raleigh 833-8898
There are approximately 250 million cars on U.S. roads today, fueled primarily by imported oil, and demand is growing. The electric utilities are in the midst of a “Smart Grid” revolution, driven by new technology, increased demand, and need for higher reliability and security. The U.S. government, along with the auto and electric utility industries, are currently striving for electrification of the transportation sector by way of plug-in hybrid and all-electric vehicles. All-electric vehicles can provide significant oil savings, improved air quality, reduced energy costs to consumers, increased energy diversity, and support for the electric grid. But are U.S. drivers ready to go all electric?
About the Speaker:
Rogelio Sullivan is the Associate Director of the Advanced Transportation Energy Center and also of the Future Renewable Electric Energy Delivery and Management Systems Center (FREEDM) at NCSU. The two research centers are working in partnership with industry to develop technologies that can effectively create the “energy internet”; which will support widespread utilization of renewable energy, plug in electric vehicles, and greater consumer participation in the energy marketplace. Mr. Sullivan is an engineer with more than 20 years of research and development management experience in advanced transportation systems such as hybrids, batteries, lightweight materials, advanced combustion engines, and vehicle auxiliary systems.
PS. Please RSVP if you can come – it is very helpful for restaurant preparations if my estimate for them is as accurate as possible: katey.ahmann@ncdenr.gov

Cooling the Planet with Geoengineering

At World Science – listen to the podcast and join the online discussion:

Our guest in this Science Forum is economist Scott Barrett of Columbia University’s Earth Institute. Chat with Barrett about the science and politics of geoengineering, the emerging field of science aimed at cooling the planet.
Barrett is an expert on international environmental agreements. He is currently studying the politics and economics of geoengineering. He says countries are more likely to geoengineer climate than reduce their carbon emissions. Read his paper on The Incredible Economics of Geoengineering.
Barrett is the author of Environment and Statecraft: The Strategy of Environmental Treaty-Making. (Here’s a review of the book.) Barrett also blogs for Yale Global Online.
Bring your own questions and comments for Scott Barrett. He’s here in the forum through April 19th. The conversation is just to the right.
