Extreme heat events are likely to become more frequent in the coming decades owing to climate change1,2. Exposure to extreme heat depends not only on changing climate, but also on changes in the size and spatial distribution of the human population. Here we provide a new projection of population exposure to extremeheat for the continentalUnited States that takes into account both of these facto...

Human-induced climate change, with such rapid and continuing global-scale warming, is historically unprecedented and signifies that human pressures on Earth’s life-supporting natural systems now exceed the planet’s bio-geo-capacity. The risks from climate change to health and survival in populations are diverse, as are the social and political ramifications. Although attributing observed health...

Dynamic models for range expansion provide a promising tool for assessing species' capacity to respond to climate change by shifting their ranges to new areas. However, these models include a number of uncertainties which may affect how successfully they can be applied to climate change oriented conservation planning. We used RangeShifter, a novel dynamic and individual-based modelling platform...

The direct and indirect health effects of increasingly warmer temperatures are likely to further burden the already overcrowded hospital emergency departments (EDs). Using current trends and estimates in conjunction with future population growth and climate change scenarios, we show that the increased number of hot days in the future can have a considerable impact on EDs, adding to their worklo...

Female education and family planning are both critical for sustainable development, and they obviously merit expanded support without any appeal to global climate considerations. However, even relatively optimistic projections suggest that family planning and female education will suffer from financing deficits that will leave millions of women unserved in the coming decades. Since both activit...

The concept of sustainable diets, although not new, is gaining increased attention across the globe, especially in relation to projected population growth and growing concerns about climate change. As defined by the FAO (Proceedings of the International Scientific Symposium, Biodiversity and Sustainable Diets 2010; FAO 2012), "Sustainable diets are those diets with low environmental impacts whi...

This paper reviews extant evidence and offers a conceptual framework for the investigation of complex dynamics among human population growth, environmental degradation, poverty, and climate change. The paper introduces theories relating to population growth, environmental degradation, the impact on human well-being, and potential relations with climate change. Poverty is discussed in detail as ...

Ensuring food security has been one of the major national priorities of Bangladesh since its independence in 1971. Now, this national priority is facing new challenges from the possible impacts of climate change in addition to the already existing threats from rapid population growth, declining availability of cultivable land, and inadequate access to water in the dry season. In this backdrop, ...

1 Altered atmospheric composition, associated with climate change, can modify herbivore population dynamics through CO2 and/or O3-mediated changes in plant quality. 2 Although pea aphid Acyrthosiphon pisum genotypes exhibit intraspecific variation in population growth in response to atmospheric composition, the proximate mechanisms underlying this variation are largely unknown. 3 By rearing sin...

The struggle for existence occurs through the vital rates of population growth. This basic fact demonstrates the tight connection between ecology and evolution that defines the emerging field of eco-evolutionary dynamics. An effective synthesis of the interdependencies between ecology and evolution is grounded in six principles. The mechanics of evolution specifies the origin and rules governin...
