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…

"Can New York City Survive the Sea?" Ted Steinberg, Davee Professor of History, Case Western University

Yale Environmental History hosts historian Ted Steinberg for a talk on New York’s ecological past and future: “Can New York Survive the Sea?”  Of his latest book, Gotham Unbound, Kirkus Review says “he has done a grand public service … examining the history of one of the most drastically transformed natural environments in the world.” 

Climate Changing the West Antarctic Food Web

The western Antarctic Peninsula is experiencing rapid climate change evidenced by warmer air temperatures, increased westerlies, glacial and ice shelf retreat, reduced sea ice cover and delayed time of sea ice formation.  The west Antarctic Peninsula food web shows influences of this rapid climate change: reduction in phytoplankton biomass, abundance of Antarctic krill and Adélie penguins have all been associated with changed environmental

Mapping Fungal Biogeography

Understanding fungal biogeography, the distribution of fungi, bacteria, and viruses, is key to understanding how ecosystems function. A thorough understanding of the ecological linkages between communities, their environment, and ecosystem function requires analysis across multiple spatial or temporal scales. In a recent study, Talbot et al. (2014) explored the taxonomic and functional distributions of fungi at the continental scale, with findings that…

Lifestyles of the High and Low GHG Emitters

Where should you live to most reduce your carbon footprint? It seems obvious that city life with smaller homes, mass transportation, and easy access to shops and restaurants is preferable to the suburbs with its cars and bigger homes. But how about the benefits of rural areas where people grow their food and live closer to the land? What about regional climate, income and energy price differences? A recent analysis by Jones and Kammen (2013)…

The Intersection of Climate and Agriculture, NRDC Executive Director Peter Lehner

Please join us Thursday, November 13, for a conversation with Peter Lehner, executive director of the Natural Resources Defense Council.

International efforts to address climate change have been bogged down – and are underperforming against the challenge of reducing the buildup of greenhouse gases in the atmosphere. The Yale Center for Environmental Law & Policy and Yale Climate & Energy Institute are hosting a speaker series this year highlighting novel approaches to climate governance.

Aerosol Sulfates. A Free Geoengineered Lunch?

In 1896 Svante Arrhenius published On the Influence of Carbonic Acid in the Air upon the Temperature of the Ground which laid out the foundation of how carbon dioxide affects global climate.  His suggestion that global coal production (then 500 million tons per year) could be so disruptive has been verified, hastened by soaring fossil fuel consumption, including a 17-fold increase in coal…

Cold-adapted Species May Be Winners Under Climate Change

As the climate warms, all species will either need to find new habitats with similar temperatures to those they currently occupy or evolve new thermal tolerances. Recent research by Araujo and colleagues suggests that some species may be able to adapt to new, higher temperatures better than others. Specifically, the authors analyzed the heat and cold tolerance capabilities of 2740 terrestrial

Dendrochronology's "Divergence Problem" Explained?

A new study by Alexander Stine and Peter Huybers offers strong evidence that reduced light availability (“global dimming”) explains the apparent lack of tree-ring evidence in many Arctic regions for the recent warming observed in instrumental records there. Dendroclimatology uses measurements of the yearly growth width and density of tree rings to reconstruct changes in past climate. The …
