Or why environmental scientists can't predict the future?
The answer given by the authors is simple. Because the scientists are trying to find exact answers to quantitative questions using models in which many parameters and interactions are still unknown.

Last year there was also a movie made, but it is as far from the book as the book is from the true story.

Nie, že by bol Obama to najlepšie, čo nás mohlo postretnúť, ale horšie ako Bush to hádam nebude a vyhli sme sa aj veteránovi McCainovi s pani Palinovou (voči ktorej som naozaj zaujatá), tak uvidíme, čo sa zmení a či sa zmení.
