Yale Environmental Sustainability Summit

How will our planet provide food, energy, and water for a growing population and as our climate changes? Can we develop more sustainable systems for producing and distributing food; drive towards lower carbon and GHG intensity in our economies; and effectively manage our increasingly scarce fresh water supplies and fragile ecosystems? How can efficiency and innovation help reduce our impact—while increasing our well-being? Can we scale up promising technologies and conservation practices to unlock unprecedented business and environmental opportunities?

Planning for future heat waves. Invoking the "Oasis" effect.

Recent and substantial increases in heat and heat wave mortality and morbidity impel society to brace for heat events of even greater severity and duration. Unfortunately, research on the relationship between future heat increases and its health impacts generally overlooks how choice of exposure metric (mean, minimum & maximum temperature) effects downstream projections. Additionally, regional growth management plans are generally not incorporated into climate impact models. Both considerations are important for…

Future Heat Stress Effects. Jonathan Buzan, Climate Dynamics Prediction Laboratory, UNH

Jonathan Buzan is a Phd candidate in Matthew Huber’s Climate Dynamics Prediction Laboratory at the University of New Hampshire.  His work on the economic and health consequences of extreme heat, including a recent New York Times op-ed, co-authored with Robert Kopp and Matthew Huber, are featured on his website,

Climate Change as Culprit in Bumblebee Decline

The alarming rate of decline of bumblebees—key pollinators of crops and wildflowers across the world and an essential part of a healthy environment— has been at the forefront of scientific news for the past several years. To date, most of the bee die-off has been attributed to changes in agricultural practices and the use of bee-killing pesticides such as neonicotinoids. Recent study, however, adds another dimension to the decline of bumblebees. Kerr et al. (2015) used over 100 years of observations across European…

How Much CO2 Can the Amazon Absorb?

Atmospheric concentration of carbon dioxide would be much higher today if not for the world’s forests, which generally act as “carbon sinks,” absorbing and storing large amounts of carbon dioxide emissions which have been rising steadily since the start of the industrial revolution.  A persistent question for climate change scientists is how much carbon dioxide can forests absorb? A recent analysis of the dynamics of the Amazon ecosystem, one of the largest forests in the world, suggests that we may be approaching the limit of how much…

Communicating Climate Change Health Impacts

There is overwhelming agreement from the scientific community regarding causes and impacts of climate change, while large segments of the US public still regard climate change as affecting the next generation and of low priority. Climate messaging that has focused on future increases in temperature and impacts such as rising sea levels could be aided by inclusion of direct health impacts and learn from targeted public health campaign strategies. Effectively communicating the health impacts of climate change and health…

Sensitivity-based Modeling to Better Estimate Future Extinction

The effects of climate change on biodiversity can be quantified by assessing vulnerability of species to changing climatic conditions. Such assessments usually include three elements: assessment of sensitivity, adaptive capacity, and potential exposure of individual species to climate change (Jarzyna et al. 2013, Foden et al. 2013). While sensitivity and adaptive capacity are generally determined by traits intrinsic to the species—physiological tolerance, behavioral traits, genetic diversity, dispersal abilities, or high reproductive rates—exposure is governed by the degree of climate change…

Vector Potential and Climate Change: Perspectives From the Pitcher-plant Mosquito. William Bradshaw

William Bradshaw presents a synopsis of his primary research which is on Wyeomyia smithy, a small mosquito that develops only within the water-filled leaves of the purple pitcher plant. As described on his website: “The fact that this mosquito is capable of blood-feeding makes it tractable for studies of the molecular genetics and evolution of the blood-feeding phenotype and for investigating the shifting patterns of vector/host interactions in the face of rapid climate change.

Land-based Strategies to Reduce Future Heat Island-related Mortality

Urban centers have been warming at double the global rate the last half-century. High daily temperatures are associated with increased mortality. Sustained increases in temperatures projected under most climate models represent a significant public health problem that may increase weather-related mortality in the United States. In a first of its kind study, Stone et al., (2014) modeled how local climate action plans that integrate land-based mitigation strategies through albedo and vegetation enhancement can mitigate future increases in heat-related mortality…
