While forecasting the state of the
environment more than 80 years into the future is a notoriously inexact exercise, academics gathered by the the United Nations at the Intergovernmental Panel on Climate Change are concerned the world is headed for «extensive» species extinctions, serious crop

sea levels even before Trump started to unpick the fight against global warming.
And don't forget the benefits arise from avoiding big problems, like scarcer water resources,
damages to human - built
environment; coastal flooding due to
sea - level rise, and human - health impacts.
