When and Where
Tuesday 13 May, 17:00-19:00 (conversation begins at 17:30)
Accelerator, Frescativägen 26A, Stockholm University (Underground station Universitetet)
Background
Our world seems to be changing at a faster pace than we can fully grasp. Many are concerned that recent geopolitical tensions and the erosion of the international non-proliferation framework are increasing the risk of nuclear warfare.
The year 2025 is, in many respects, a pivotal one. It marks the 80th anniversary of the atomic bombings of Hiroshima and Nagasaki. It is also the 25th anniversary of Paul Crutzen’s proposal that humanity has entered a new geological epoch: the Anthropocene. Looking ahead, 2026 will mark the 35th anniversary of the closure of the Soviet nuclear testing site, the Polygon, in Semipalatinsk, Kazakhstan.
What is the political legacy of the horrifying bombings of Hiroshima and Nagasaki? What does life look like today in the Polygon and its surroundings? And finally, what can we in Sweden learn from their histories as we grapple with a future marked by increasing geopolitical tensions and the growing risk of nuclear weapons use?
