World must act now or face worst case climate scenario

Even for a military man like me, the latest scientific evidence on global warming — endorsed by the 195 member countries of the UN Intergovernmental Panel on Climate Change — makes for a chilling read.

The scenarios set forth in the report indicate that if the world continues on its current track, burning more and more fossil fuels and increasing the levels of pollution in our atmosphere year after year, global average temperatures could rise by 4C by the end of the century.

That amount of warming would cause sea levels to rise, displacing tens of millions of people worldwide. It would disrupt weather systems, destroying harvests and threatening populations with droughts, floods, and storms of ever-increasing intensity. It would also place a massive strain on global water resources.
