The word Anthropocene has been used over the past 20 years to define the modern era during which time man has come to shape the environment.  This reality became significantly more pronounced with the advent of the nuclear Anthropocene.  As Prof. Higuchi explains in the introduction of  "Political Fallout," from 1945 to 1963, when the Partial Test Ban Treaty (PTBT) was signed by the US, the Soviet Union and Britain, these three nations conducted approximately 450 nuclear weapons tests, in sum equal to 26,000 Hiroshima-sized bombs, that caused worldwide radioactive contamination.  Though in small concentrations, radioactive particles from this period of atmospheric nuclear weapons tests are still present around the world.  How and why the 1963 Partial Test Ban Treaty, signed by the US, the Soviet Union and Britain, came into effect remains important.  Among other reasons, this past August the UN Secretary General, Antonio Guterres, concluded the world has entered “a time of nuclear danger not seen since the height of the Cold War.”  Two weeks ago the Science and Security Board of the Bulletin of the Atomic Scientists forwarded its Doomsday Clock to 90 seconds to midnight.  The clock has move forward 4:30 since 2010.  This history is also important because it potentially offers lessons regarding how we address the climate crisis.   

During this 46 minute discussion, Prof. Higuchi begins by defining the Japanese word hibakusha and defines what is radioactive fallout.  He next discusses how concerns regarding nuclear fallout became publicly known, how the US's understanding of radioactive contamination evolved through the 1950s, discusses his "politics of risk" framework used to discuss fallout's biological effects, social acceptability and policy implications, how ultimately a PTBT was achieved, and discusses what lessons can be learned from the nuclear Anthropocene relative to the climate crisis.
