Local residents, businesspeople, and policymakers engaged in climate change adaptation often think differently of the time available for action. Their understandings of time, and their practices that invoke time, form the complex and sometimes conflicting temporalities of adaptation to environmental change. They link the conditions of the past to those of the present and the future in a variety of ways, and their contemporary practices rest on such linking explicitly or implicitly. Yet the temporal connections between the present and distant future of places are undertheorized and poorly considered in the science and policy of adaptation to environmental change. In this article we address this theoretical and practical challenge by weaving together arguments from social and environmental geography with evidence from small coastal communities in southeastern Australia. We show that the past conditions residents’ imagined futures and that these local, imagined futures are incongruent with scientific, popular, and policy accounts of the future. Thus we argue that the temporalities of adaptation include incommensurate and unacknowledged ways of knowing and that these affect adaptation practices. We propose that strategies devised by governments for adapting to environmental change need to make visible—and calibrate policies with—the diverse temporalities of adaptation. On this basis, the times between the present and the long-term future can be better navigated as a series of short and negotiated policy steps. [ABSTRACT FROM PUBLISHER]

Changing climates are affecting biodiversity and natural systems, causing extinctions, range shifts, and phenological shifts. Efforts to forecast the spatial distribution and magnitude of these effects, however, have focused largely on direct effects of changing climates on species' distributional potential; recent work has considered secondary effects of warming climates via rising sea levels. Here, we present a first integration of the two dimensions of climate change effects on biodiversity, examining joint effects of marine intrusion and climate change on the distributional potential of seventy-six species of Mexican birds. The two phenomena are not related to one another—that is, a species seriously affected by one is not necessarily seriously affected by the other; however, the areas affected within species' distributions by the two phenomena tend to be complementary, compounding the negative effects. These results have implications for planning biodiversity conservation globally. [ABSTRACT FROM AUTHOR]
