We have visited Mars several times in the past but perhaps no mission to the Red planet is as ambitious as the one underway right now. After months of interplanetary flight and a flawless landing, Mars Rover Curiosity has already begun to explore the planet’s surface. The aim of the mission; find signs of life on Mars. We’ll meet one of the principal members of the mission’s team, geobiologist Dawn Sumner, as we continue our geology conference series when Charlotte Talks.

One of the issues we’ve heard little about during this election campaign is climate change. But Hurricane Sandy has thrust the topic into the spotlight. It is a complex, challenging problem both scientifically and politically but on election day, we step away from the politics and focus on how scientists are communicating with those who make public policy to help them and citizens understand what is happening and the potential consequences.

Sea levels all over the east coast are rising. There is generally no dispute about that. But there is much debate about how high our Atlantic sea levels will rise, how fast it will happen and what affect it will have on our coast and the eastern seaboard. We begin a series exploring the biggest geological and geopolitical topics in current times. First up, Dr. Rob Young, an expert on sea levels who says that current predictions could be far short of potential rising seas. We meet Dr. Young and learn more about rising sea levels when Charlotte Talks.

Native American Trail Trees (Rebroadcast)

Oct 1, 2012

It has been hundreds of years since the intersection of Trade and Tryon was a place where two Native American trading paths crossed but signs of that ancient network of tribal travel and culture are all around us. Right now, two men, among others, are in the midst of mapping the main travel routes of the Cherokees and other tribes as well as the guideposts they used. Many of the guideposts are trees and we'll learn about efforts to preserve them.

A new North Carolina law that allows the state to override local tree-protection ordinances has resulted in the loss of several hundred trees that covered at least 50 acres near billboards in Charlotte, according to the city's arborist. 

How the legislation is implemented is still being determined by the state Department of Transportation. The process involves a public comment period that ends Friday.

Air

Aug 23, 2012

Air is all around us, and we breathe 30,000 times a day. We depend on air for life itself, but how much do we know about it? Author William Bryant Logan has asked, and attempted to answer many questions about air that we might never have thought to consider. He’s put them into his new book, Air: The Restless Shaper of the World. He’ll join us to talk about the many ways we interact with air, and the many forms that air takes.
