  • Uncertainty of climate change and its impact on reference evapotranspiration in Rasht City, Iran

    There are many factors of uncertainty regarding the impact of climate change on reference evapotranspiration (ETo). The accuracy of the results is strictly related to these factors and ignoring any one of them reduces the precision of the results, and reduces their applicability for decision makers. In this study, the uncertainty related to two ETo models, the Hargreaves-Samani ...

  • Thermodynamics of climate change

    Climate modelling is discussed from a thermodynamic point of view, using a control volume approach in which the environment and a superficial layer of the earth form the volume, concentric spherical shell of predominantly gaseous content with a thin layer of the earth. An energy equation that includes anthropogenic heat is suggested based on the mass balance of fossil fuel introduced into the ...

  • Towards a definition of climate science

    The intrinsic difficulties in building realistic climate models and in providing complete, reliable and meaningful observational datasets, and the conceptual impossibility of testing theories against data imply that the usual Galilean scientific validation criteria do not apply to climate science. The different epistemology pertaining to climate science implies that its answers cannot be singular ...

  • Climate variations for the last millennium

    Variability and long-term climate change in the Baltic Sea region have been investigated in a 1000-year long climate model simulation. For the first time long-term climate variations over the region have been simulated with a regional climate model. Solar variability, changes in orbital parameters and changes in greenhouse gases over the last millennium are used to force the models. The results ...

  • Simulated precipitation response to SST forcing and potential predictability in the region of the South Atlantic convergence zone

    The sensitivity of the precipitation response in the South Atlantic convergence zone (SACZ) to sea surface temperature (SST) anomaly is investigated by an inter-model comparison study of ensembles of multidecadal integrations of two atmospheric general circulation models (AGCMs)—version 1 of the NASA Seasonal-to-Interannual Prediction Project (NSIPP-1) model, and the NCAR community climate model ...

  • Climate change adaptation in British Columbia communities: lessons for planners

    The purpose of this paper is to explore community adaptation to climate change. We illustrate how a workshop format can be used to raise awareness about the need for adaptation in communities and to engage planners in finding solutions. Professionals can no longer rely on the past as a proxy for the future. Communities will have to become more resilient to an uncertain future, and planners must ...
