Slide 21: Use of GCMs
GCMs enable us to better understand the processes that drive the climate. Models that work better at describing climatic conditions generally give us an insight into how the various physical characteristics of the earth are interacting.
They allow us to make informed and scientifically defensible predictions based on current understanding of the climate.
By running the models on palaeoclimatological data, an understanding of long-term climate effects far beyond the age of even the human race can be established.
GCMs are thus the best tools for all climate science, and allow conservationists, planners and politicians to test different response scenarios.
