4.6. Conclusion

Through much of the history of climate modelling, division between modelling and observational studies has hampered the development of both sides. The coupling of these theoretical and empirical disciplines, to test both model accuracy and understanding gained from analysis of observational data, has only recently been addressed. Much of the discrepancy between the climate model and real world is the result of this division. Such a divide must be bridged if accurate forecasts of future climates are to be produced.
