It was the problem of considering climate as an average of weather where there is abrupt change between different states.
It s a problem because the average either under or over estimates the reality. For rainfall in Australia - if you calculate water supply based on the 100 average and there is a 20 to 40 year 'Drought Dominated Regime' - we risk running out of water. Most cities in Australia came too close for comfort to this in recent times.
