A straight-talking expert on climate warming is to visit Northland during a speaking tour about the crisis that is decimating natural habitats.
Professor Guy McPherson pulls no punches in sharing his concerns that Earth is experiencing losses of natural habitats at faster rates than predicted, and mass extinction events are almost certain.
Unapologetically at the extreme end of the debate, he believes the loss of habitat poses the single most serious threat to the survival of all species.
He predicts climate change is irreversible and human extinction is almost inevitable.
Dr McPherson is an American scientist and professor emeritus of natural resources, ecology and evolutionary biology at the University of Arizona.
