Failures of Nuclear Safety and Regulatory Reform in Japan -- The Case of Fukushima. Professor Hideaki Shiroyama, Vice Dean, Graduate School of Public Policy, The University of Tokyo

Professor Hideaki Shiroyama, Graduate School of Public Policy at The University of Tokyo (Todai), will be visiting Yale on Friday, February 28, 2014, and will give a Special Lecture in the YCEI series on Interdisciplinary Topics in Energy. The lecture will discuss failures of regulatory policy and nuclear safety in Japan, along with proposals for reform, in light of the accident at the Fukushima Nuclear Power Plant, which was caused by the Great East Japan Earthquake and the resulting tsunami on March 11, 2011.

When Evolved Behaviors Backfire

Frogs that eat holiday lights, birds that eat plastic, and beetles attempting to mate with beer bottles are all examples of organisms that have fallen victim to what biologists call “evolutionary traps.”  Whereas natural selection typically produces organisms that behave in ways to maximize their fitness, resulting in more offspring passing their genes onto the next generation, human actions sometimes short-circuit the process…

The Importance of Model Resolution in Global Change Biology

Biologists increasingly realize that understanding the impact of global change on biological processes requires accounting for fine-grain environmental variability (Potter, Arthur Woods, & Pincebourde, 2013). Similarly, climatologists have found that increasing the resolution of climate models typically produces better simulations of climate and precipitation…

Impacts of Aerosols on Arctic Mixed-Phase Boundary Clouds During M-PACE and ISDAC Field Campaigns: Implications for Modelling Studies

Comprehensive data on arctic boundary layer aerosol and cloud microphysical and radiative properties were collected during the 2004 Mixed-Phase Arctic Cloud Experiment (M-PACE) and the 2008 Indirect and Semi-Direct Aerosol Campaign (ISDAC). During M-PACE, the University of North Dakota Citation executed spiral ascents and descents through 27 mixed-phase clouds on 7 separate days over ground-based remote sensing sites at Barrow and Oliktok Point, Alaska.

Global Carbon Dioxide Emissions from Inland Waters

Carbon dioxide transfer from inland waters to the atmosphere is a significant component of the global carbon cycle. Global estimates of CO2 transfer have been hampered, however, by a lack of a framework for estimating the inland water surface area and gas transfer velocity and the absence of a global CO2 database. Here we report regional variations in global inland water surface area, dissolved CO2 and gas transfer velocity.

Ending This Climate Madness

By Alisa Zomer

Even before the climate negotiations began this week, Typhoon Haiyan sent a message to the world – a message that is still making waves. The strength and trajectory of Typhoon Haiyan was unprecedented, even for the Philippines, an island nation that experiences more disasters than most. In response, the lead Filipino negotiator declared a fast for the duration of the climate negotiations until progress has been made to “stop this madness.”
