News and commentary for the week of May 16 - May 22, 2007 with Mike Kaspar and Nathan Callahan.

George Monbiot discusses his book Heat: How to Stop the Planet from Burning. It now seems certain that we need a 90% cut in our emissions within 25 years if we are to stop ourselves reaching the point where the "climate feedback" becomes unstoppable, and our world becomes largely uninhabitable. Monbiot explains how this cut could be achieved. Combining his knowledge of political campaigning and environmental science, he analyses the possibilities and pitfalls of energy efficiency, nuclear power, renewable resources and new technologies, and applies them to our everyday lives, measuring the cuts that can be made.

Monbiot is a bestselling author and a weekly columnist for the Guardian. In 1995 Nelson Mandela presented him with a United Nations Global 500 Award for outstanding environmental achievement. He has been named by the Evening Standard as one of the 25 most influential people in Britain, and by the Independent on Sunday as one of the 40 international prophets of the 21st Century. His books include Captive State: the Corporate Takeover of Britain and, most recently, The Age of Consent: A Manifesto for a New World Order.

An interview with Andrew Koppelman author of "Same Sex, Different States: When Same-Sex Marriages Cross State Lines."

Americans are profoundly divided over same-sex marriage, and now that gay civil unions and marriages are legal in some states, the issue has become increasingly urgent. Koppelman offers a sensible approach that will appeal to the best instincts of both sides. Drawing on historical precedents in which states held radically different moral views about marriage (for example, between kin, very young individuals, and interracial couples), Koppelman shows which state laws should govern in specific situations as gay couples travel or move from place to place.

Koppelman is professor of law at Northwestern University School of Law and author of Antidiscrimination Law and Social Equality and The Gay Rights Question in Contemporary American Law.
