The turnover of phylogenetic clades across space is a fundamental biodiversity pattern that may depend on long-term evolutionary processes, and that has downstream effects on other aspects of diversity including species richness and community structure. Limited niche evolution and limited dispersal are two major processes causing spatial restriction, and thus turnover, of clades. We studied the...

Despite increasing concern about elevated extinction risk as global temperatures rise, it is difficult to confirm causal links between climate change and extinction. By coupling 25 years of in situ climate manipulation with experimental seed introductions and both historical and current plant surveys, we identify causal, mechanistic links between climate change and the local extinction of a wid...

a sensitivity analysis of the flood safety of solaimantangeh dam using a regional climate change simulation is presented. based on the output of the ccsm (community climate change system model) general circulation model, the nircm (north of iran regional climate model) computes regional scale output with 50 km spatial resolution and 21 vertical layers. using the sres (special report emission sc...

this research studies the potential impact of climate change on future trend and changes of two well known drought indicators namely rdi and spi in yazd meteorological station, in central part of iran. for this purpose, data of hadcm3 model that were resulted from gcm-runs based on the ipcc-sres scenarios of a2 and b2 were acquired and analyzed for projection of daily tmin, tmax and precipitati...

Although climate change can induce large-scale impacts on industrial supply chain networks, first empirical studies suggest that adaptation to climate change is only slowly emerging as a management topic in firms. The present study examines why managers often do not engage their firms in adaptations to climate change. Thereby the study focuses, in particular, on the lack of strategic adaptation...

This work develops and describes a formal probabilistic protocol via which the process of identifying lines of evidence for climate change, assessing likely causes for changes in the evidence, and combining the lines of evidence to make overall attributions of cause to greenhouse gases can be made. This open and detailed model of the detection and attribution process is designed to identify iss...

[1] We investigate the effects on U.S. ozone air quality from 2000–2050 global changes in climate and anthropogenic emissions of ozone precursors by using a global chemical transport model (GEOS-Chem) driven by meteorological fields from the NASA Goddard Institute for Space Studies general circulation model (NASA/GISS GCM). We follow the Intergovernmental Panel on Climate Change A1B scenario an...

There may never have been an instance of environmental pollution to challenge our powers of analysis and evaluation quite like climate change. Global in its causes and consequences, spanning many generations, and poorly understood but with the potential to transform the natural environment, climate change has highlighted challenging questions of the economics of risk, of distribution amongst in...
