On Wednesday, WBEZ education reporter Linda Lutton explains the updated agreement reached by CPS and the CTU Tuesday to Eight Forty-Eight. Then, we'll talk with Larry Kalkstein and Steve Frenkel of the Union of Concerned Scientists about whether the unusually dry summer is the result of a new longterm weather pattern. Peg Solaski-Dorchack of MacCormac College joins after that; she leads the nation's oldest court reporting program, which celebrates its 100th anniversary this year. And history blogger John Schmidt will join us with a centennial quiz. Call 312.923.9239 to play.
