Record high temperatures in the ocean around Florida, wildfires and heat waves across Southern Europe, and flash floods and freak storms elsewhere have stirred fears of catastrophic climate change.
But another kind of climate change is also at work. The global political climate is heating up, and the rising geopolitical temperature is likely to hit faster and could wreak more havoc than anything Greenpeace is worried about. Geopolitical climate denialism is a more urgent danger to national security than melting glaciers in Greenland.
