Habitat Corridors: Saving Species. Storing Carbon

One way species adapt to changing climatic conditions is by moving their geographic ranges in the direction of changing climatic niches, usually to either higher latitude or elevations. Successful range shifts, however, are contingent upon the ability of a species to migrate to the new, climatically suitable locations. For example, species might be unable to migrate due to their intrinsic characteristics (e.g., sedentary life style or short dispersal distances) or because of lack of suitable habitats between its current…

Climate Change Impacts on Coral Reefs Felt in Surrounding Ecosystems

Studies have shown that variation in species responses to changing climate will result in disruption of biotic interactions such as predation, parasitism, competition, and mutualism, ultimately leading to changes in community composition and ecosystem functioning (e.g., Both et al. 2009). Just as different species are linked by a network of interactions, ecosystems are connected by…

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.

New York City's Special Initiative for Rebuilding and Resilience: Strengths and Limitations of Climate Model-Based Approaches

Radley Horton from Columbia University Earth Institute will speak on climate projections for New York City.  The $20 billion Special Initiative for Rebuilding and Resiliency (SIRR) Plan for New York is grounded upon climate risk information provided by the New York City Panel on Climate Change (NPCC). This expert panel, tasked with advising the City on climate-related issues, completed a ‘rapid response’ climate assessment with updated climate projections.

Unusual Southern Hemisphere Tree Growth Induced by Ozone Depletion

Earth’s climate system includes several patterns of climate variability at the hemispheric scale. One of the best known of these is the El-Nino/Southern Oscillation, which influences weather across much of the globe. Another important feature of the climate system is the Southern Annular Mode (also known as the Antarctic Ocean Oscillation), which is an index of the pressure gradient between the mid- and high-latitudes in the Southern Hemisphere. Over the last few decades, the dominance of the positive phase of the Southern Annular Mode has been increasing.
