To improve linkages between climate and economic models, climate modelers must improve regional forecast accuracy and economic models must include explicit climate-sensitive functions. The spatial mismatch between geometric grids must be overcome to develop a useful global climate-economic model. Proper use of models will not be to predict extreme calamities but to run alternate simulations and investigate potential magnitudes of total costs, relative gains and losses, and possible courses of action to minimize disruption or maximize opportunity.
More work is still necessary to prepare for instead of simply react to climate change.
Climatic Res., Univ. This data has been systematically compared with the model simulations of past climates. Comparisons of paleoclimatic data with the model simulations are important because models provide a theoretical framework for evaluating mechanisms of climatic change, and such comparisons help to evaluate the potential of general circulation models for predicting future climates. It appears that in the late 1970s chlorine exceeded some critical level, below which nitrogen naturally dominated chlorine and protected ozone. Now with nitrogen tied up in ice particles, chlorine is released in ozone-destroying form.
