Geoengineering Impacts on the Hydrological Cycle

Jon Egill Kristjansson reviews his work on aerosols, their influence on cloud formation, and how the level at which those clouds forms determines the radiative effect on earth’s climate system. He reviews four approaches to Radiative Management (RM), ie., that part of geoengineering which relates to atmospheric manipulation of albedo to combat global warming, and shares model projections on how that impacts what matters more to human survival than temperature increase, ie., the availability of water through impacts to the hydrological cycle.

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…

Habitat Corridors: Saving Species. Storing Carbon

One way species adapt to changing climatic conditions is by moving their geographic ranges in the direction of changing climatic niches, usually to either higher latitude or elevations. Successful range shifts, however, are contingent upon the ability of a species to migrate to the new, climatically suitable locations. For example, species might be unable to migrate due to their intrinsic characteristics (e.g., sedentary life style or short dispersal distances) or because of lack of suitable habitats between its current…

Rain Water Harvesting: An Adaptive Strategy for Tamil Nadu, India

Rainwater harvesting (RWH) is an ancient technique to store water for domestic or agricultural use. It can be an important technology for regions where rainfall variability threatens water and food supplies and economic security. As such, it has the potential to be an important adaptation technology for resource-limited communities to counter the increased variability of rainfall patterns from climate change. A review article in

Evolution in the Anthropocene. Jason Munshi-South

Jason Munshi-South, associate professor of Biology at Fordham University’s at Fordham University’s Louis Calder Center, describes ongoing efforts to develop species such as New York City’s white-footed mice as models for examining the evolutionary implications of urbanization. Also discussed are potential similarities between evolutionary responses to climate change and urbanization. Jason’s lab integrates complementary approaches from landscape ecology, urban ecology, and population genomics.

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

Large-scale Electrification: The Stress Nexus With Water. Karen Hussey

Karen Hussey is Associate Professor at the Fenner School of Environment and Society at the Australian National University (ANU) where she undertakes research on policies, institutions and governance for sustainable development. She leads several projects assessing the effectiveness of Australian laws and policies for supporting adaptation to climate change.
