“I think we are headed for major societal disruption within the next five years,” said Gretta Pecl, at the University of Tasmania. “[Authorities] will be overwhelmed by extreme event after extreme event, food production will be disrupted. I could not feel greater despair over the future.”
One book I read predicted societal disruption for 2035, with a total collapse of nations around 2050. I found it overly dramatic at the time, but now, 15 years later, it seems we're well ahead of that prediction.
