agriculture is one of the main sectors affected by climate change. although recently some studies about the nature and size climate change effect on the physical variables of water resources and agriculture have been done, however economic perspectives and the role of adaptation strategies have been less studied empirically. the contribution of this study is modeling real economic behavior of s...

Some recent research suggests that uncertainty about the response of the climate system to atmospheric greenhouse gas (GHG) concentrations can have a disproportionately large influence on benefits estimates for climate change policies, potentially even dominating the effect of the discount rate. In this paper we conduct a series of numerical simulation experiments to investigate the quantitativ...

Agricultural production systems face increasing threats from more frequent and extreme weather fluctuations associated with global climate change. While there is mounting evidence that increased plant community diversity can reduce the variability of ecosystem functions (such as primary productivity) in the face of environmental fluctuation, there has been little work testing whether this is tr...

Models simulate responses of future climate to scenarios for anthropogenic emissions. While the uncertainty of these simulated responses is not established, perspective on uncertainty is provided by the intercomparison of the responses of alternative models. The envelope of alternative model simulations, if plausible responses, must be contained within the uncertainty range. In this way model i...

This paper presents the results of a web based survey assessing the usability of main uncertainty visualisation methods for users belonging to different key domains such as GIS and Climate change research. We assess the usability of the visualisation methods based on the user's performance in selected learnability tasks, in addition to assessing user preferences. A correspondence analysis betwe...

Aim NARCliM (NSW/ACT Regional Climate Modelling project) is a regional climate modelling project designed to provide regional climate change data for use in impacts and adaptation research across sectors. Method The climate models used were carefully chosen to satisfy the following criteria:  The chosen models perform adequately for the recent past compared to observations.  The chosen models...

While the foundations of climate science and ethics are well established, fine-grained predictions, as policy-decisions, beset with uncertainties. This chapter maps uncertainties classifies them to their ground, extent, location. A typology uncertainty is presented, centered along axes scientific moral uncertainty. illustrated paradigmatic examples in science, ethics, economics. The discusses I...

increased concentration of greenhouse gases is expected to alter the radiative balance of atmosphere, causing increases in temperature and changes in precipitation patterns and other climatic variables. these changes are associated with the changes in hydrological systems globally and at the basin scale. these changes include: precipitation patterns and extremes; the amount and generation of ri...

Uncertainty is a pervasive feature of climate change analysis. This paper explores the consequences for policymakers. Importantly, uncertainty means that every policy has a range of possible outcomes rather than a single estimate. At a minimum, this requires policymakers to decide how to compare these different outcomes and to determine the likelihood that each outcome occurs. While objective a...
