With Tucson's climate just about ideal in December, it's difficult to think about what the weather will be like in six months, let alone 65 years. But it's essential to do so. The alternative is to ignore the plight that future generations are likely to face as a result of predicted changes in the climate.

One climate change study after another — the most recent published in the fall — indicates that the consequences of not thinking that far in advance could be cataclysmic. The recent study deals with what's likely to happen to our climate by 2071.

Prepared by scientists at Purdue University in Indiana, the study says "dramatic ecological, economic and social consequences" could result from an increase in the number of extremely hot days and additional precipitation that computer models are forecasting.
