It is not news that climate shapes history. What is news is that the heating of our atmosphere has propelled our climate into a new state of instability. This new era of climate change could well be the most profound threat ever facing humanity.
Climate change is far more than a merely environmental issue.
The crisis of the global climate clusters together three issues of enormous scope and pervasive impact. Its natural dimensions are of truly cosmic proportions. The eleven hottest years in recorded history have occurred since 1983. The period from 1991 to 1995 constitutes the hottest five-year period on record. 1998 just replaced 1997 as the hottest year in human history.
