When the Academy Award-winning producer of An Inconvenient Truth, Lawrence Bender, wanted to create a new nuclear proliferation film in the same vein, he turned to leading experts at Harvard Kennedy School's Belfer Center. The resulting film, Countdown to Zero, now open in select cities, focuses on the reality of nuclear danger in today's world and makes an urgent case for securing nuclear materials against terrorists.

Olli Heinonen, deputy director general of the International Atomic Energy Agency and the world's leading outside expert on Iran's nuclear program, will join Harvard Kennedy School's Belfer Center for Science and International Affairs as a Senior Fellow this fall.

Shortly after the Sept. 11 attacks, the well-known economist Martin Feldstein, a longtime member of the Belfer Center Board of Directors, introduced a new course at Harvard: the Economics of National Security. For Feldstein, the attacks crystallized an idea that he had been thinking about for years: Unlike other critically important national issues such as health care and crime, very few economists do any work on national security. Feldstein hoped his course at Harvard would change that.

As more than 40 heads of state convene in Washington for President Obama's nuclear security summit, a new report released today, finds that despite significant progress, the world is not yet on track to meet the Administration's goal of securing all stockpiles of nuclear weapons and weapons-usable nuclear materials, within four years. To meet the four-year objective President Obama set in Prague in April 2009, global leaders must redouble efforts following the upcoming nuclear security summit, shifting the global nuclear security effort onto a faster and broader trajectory, according to Securing the Bomb 2010.

CAMBRIDGE, Mass. — A new study from current and former researchers at Harvard Kennedy School's Belfer Center for Science and International Affairs finds that reducing greenhouse gas emissions from transportation will be a much bigger challenge than conventional wisdom assumes — requiring substantially higher fuel prices combined with more stringent regulation.

Rolf Mowatt-Larssen spent more than two dozen years in intelligence, both in the CIA and U.S. Department of Energy. After the Sept. 11 terrorist attacks, he led the U.S. government's efforts to determine whether al Qaeda had WMD capabilities and to prevent a nuclear terrorist attack on the United States. He is now a senior fellow at the Belfer Center. In January, Mowatt-Larssen published a timeline of al Qaeda's attempts to acquire WMD.
