Following former Vice President (and Nobel Laureate) Al Gore's testimony before the Senate Foreign Relations Committee on Wednesday, the Union of Concerned Scientists strongly supported Gore's testimony in pushing for a "to address the urgency of the climate crisis." Here is a statement from Alden Meyer, the UCS director of policy and strategy: "Once again, Vice President Gore is speaking the inconvenient truth: It's long past time for the United States to join the rest of the world in the fight against global warming, and it's essential for Congress to pass comprehensive climate legislation this year. The United States has joined other countries in calling for adoption of a new climate change treaty at the Copenhagen climate summit this December. Having a congressionally approved plan in hand would strengthen President Obama's ability to negotiate a strong agreement in Copenhagen

UC-Berkeley professor of energy Dan Kammen is well-known around the country and throughout the world for his work in renewable energy science and policy. Recently, he and a team of academics, entrepreneurs, business leaders and policymakers released a 141-page report, 18 months in the making, called "The Gigaton Throwdown'' that outlines a path for a dramatic expansion in the development and deployment of renewable and low-carbon energy. The team focused on what it would take for nine different technologies to reduce the annual emissions of carbon dioxide and equivalent greenhouse gases by a least 1 billion metric tons, or one gigaton, by 2020. A copy of the report has been widely distributed on Capitol Hill, and has been presented to Energy Secretary Steven Chu, a colleague of Kammen's. The Mercury News talked to Kammen about the report, some of its conclusions and whether it can have an impact on U.S. energy policy. The interview was edited for clarity.

A Nuclear Regulatory Commission (NRC) member's recent call for the agency to require nuclear power plants to better protect high-level radioactive waste on site was seconded by the Union of Concerned Scientists (UCS), which has advocated for safer storage of spent nuclear fuel rods for years. In a May 13 speech at a nuclear industry trade group forum, NRC Commissioner Gregory B. Jaczko said it is much safer to store spent nuclear fuel rods in steel and concrete containers, called dry casks, than in large water-filled concrete pits, known as wet pools. He recommended that his agency require plants to expeditiously transfer spent fuel from wet pools to dry casks rather than allow it to accumulate in the pools.
