“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.

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.
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.
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…
Research published in Science has highlighted 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…
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…
A farmer in the central USA and a fisherman in Maine will not experience global warming in the same way. Dynamic interactions between cities, deserts, and forests mean that a rise in the global mean temperature doesn’t imply uniform warming of the planet. As climate change advances, wind patterns and ocean currents will shift; the sea may swell in some places, while rivers run dry in others. Global climate models make predictions on too broad a scale to recognize many of these effects, leaving policy makers unable to prepare their communities.

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.”
