"Polluters Talk. We Walk." NGO's Make Themselves Heard at COP 19

“Polluters talk, we walk” was the chant two weeks ago, as thousands of climate change activists walked out of the 19thUnited Nations Council of Parties (COP 19) conference a day before negotiations were scheduled to end. A spokesman for Oxfam blamed negotiators for insufficient outcomes to limit global temperature rise to 2 degrees Celsius as outlined by the United Nations Intergovernmental Panel on Climate Change.

First United Nations Resilience Academy Held in Bangladesh

By Elizabeth Tellman

Densely populated, and with 80% of its area located on a floodplain within 8 meters of sea-level1, Bangladesh is one of the world’s most flood-prone nations.  As such it’s an appropriate setting for a series of two United Nations University Resilience Academies that convene experts in research, policy and practical applications to help developing nations deal with the effects of climate change.

Cloud Seeding: A Geo-Engineered Response to Climate Change?

Clouds, air pollutants, and the underlying landscapes all impact Earth’s energy budget in complex and competing ways.  Atmospheric scientists from Yale and Tokyo’s Todai University gathered at a YCEI sponsored forum in September to share how they use climate models to study how humans affect this nuanced system—and how we can possibly counteract global warming by manipulating cloud formation.

Global Decadal Hydroclimate Variability in Observations and Models, with Richard Seager of Lamont-Doherty Earth Observatory

Richard Seager is the Palisades Geophysical Institute/Lamont Research Professor at the Lamont Doherty Earth Observatory of Columbia University.  He studies climate variability on seasonal and millenial scales and is particularly interested in periods of extended drought through history. Most recently he has focused on the causes of North America drought and its connection to oceanic temperature variations.

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…

Global Food Security

Research published in Science highlights the potentially deleterious effects of climate change on global food security. As defined by the United Nations’ Food and Agriculture Organization, food security has a number of components.  These include food availability, access and utilization…

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…
