Benefits Outweigh Costs of Massive Renewable Energy Deployment

The power grid is a massively complicated network of generators, power converters, and transmission lines controlled through the cooperation of numerous private corporations and local and international agencies. Grid operators rely on long and short-term “to-the-minute” weather predictions and other inputs to predict demand and prevent disruption. Government policies and economic constraints of the coming decades require the grid in the United States (and elsewhere) to become even more intelligent, interconnected, and efficient.

Global Environmental Justice: A Public Political Ecology of the Carbon Economy

Tracey Osborne is Assistant Professor in the School of Geography and Development and Director of the Public Political Ecology Lab at the University of Arizona. Her research investigates the political ecology of environmental markets, particularly carbon markets, and their implications for the lives and livelihoods of forest communities in the Global South. Specifically, she explores the intersection of carbon markets, development, and agrarian change as they relate to forestry-based carbon initiatives in Mexico.

Praxis, Ethics & Outcomes From Doing Science in a Nuclear World

Our featured speaker is Barbara Rose Johnston of the Center for Political Ecology. Barbara is an environmental anthropologist whose research explores the linkages between environmental crisis and human rights abuse, seeking acknowledgment and implementation of the right to a healthy environment, environmental equity, and the right to reparation and remedy.

Climate-Ecosystem Carbon Feedbacks

Respiration by plants and microorganisms is primarily responsible for mediating carbon exchanges between the biosphere and atmosphere. Climate warming has the potential to influence the activity of these organisms, altering the exchanges between carbon pools. Traditionally, the respiratory release of CO2 into the atmosphere is thought to be more temperature-sensitive than photosynthesis (carbon fixation), generating a positive climate-ecosystem carbon feedback with the potential to accelerate climate warming by up to 1.4 times.
