The issue focused on greenhouse gases


Abstract The greenhouse gases generated by fossil fuels make up 80 percent of global greenhouse gases and contribute 40 percent of greenhouse gases in Earth's atmosphere. Given our limitations and uncertainties regarding climate science and estimates of carbon dioxide concentrations in human emissions, future greenhouse gases must be evaluated using techniques including simulations and numerical simulations of anthropogenic forcings that incorporate anthropogenic forcings into models and assessments of anthropogenic forcings through instrumental sciences and modeling methods. Based on analyses of modeling techniques such as numerical
