Global warming, we are told, will affect the lives of every human being and species of animal, plant and marine life on earth. But according to Daniel Botkin in an article in the Wall Street Journal, there isn't much evidence to support the theory that global warming will be destructive. In fact, the evidence seems to point to the contrary.
He points out that over the last 2.5 million years the earth has undergone several dramatic climate changes and yet very few species have become extinct, the exception being large mammals from the last ice age, such as sabre-toothed tigers and wooly mammoths.
He also disagrees that global warming will increase the incidence of epidemics of some diseases, stating that global warming has not widened the distribution of diseases such as malaria and encephalitis and it is not likely to do so in future. He points to research done at Oxford University that supports this statement.
Botkin is president of the Center for the Study of the Environment and professor emeritus in the Department of Ecology, Evolution, and Marine Biology at the University of California, Santa Barbara.
