Examining Risks, Extreme Events, and Abrupt Changes

Uncertainty, Instability and Irreversibility in the Earth System; Yokohama, Japan, 11–13 March 2013



Climate change research in Japan has shifted focus significantly in the past 2 years, with a greater emphasis on risks, extreme events, and abrupt changes. Two new national government-funded 5-year projects, Integrated Climate Assessment—Risks, Uncertainty and Society (ICA-RUS) and Program for Risk Information on Climate Change (SOUSEI) will focus on climate-induced risks and hazards and the possibility of fast climate changes. In light of the devastating Tohoku earthquake, tsunami, and consequent nuclear accident that occurred 2 years ago in Japan, there is also an increased interest in looking again at risks previously thought to be highly unlikely and in searching for potential risks that have not been considered.
