In February President Obama said, a little carelessly, that climate change is a greater threat than terrorism. Next week he will be in Paris, a city terrorized yet again by mass murderers, for a summit with other world leaders on climate change, not terrorism.

What precisely makes these world leaders so convinced that climate change is a more urgent and massive threat than the incessant rampages of Islamist violence?

It cannot be what is happening to world temperatures, because they have gone up only very slowly, less than half as fast as the scientific consensus predicted in 1990 when the global-warming scare began in earnest.

Even with this year’s El Niño-boosted warmth threatening to break records, the world is barely half a degree Celsius (0.9 degrees Fahrenheit) warmer than it was about 35 years ago. Also, it is increasingly clear that the planet was significantly warmer than today several times during the past 10,000 years.

Nor can it be the consequences of this recent slight temperature increase that worries world leaders. On a global scale, as scientists keep confirming, there has been no increase in frequency or intensity of storms, floods or droughts, while deaths attributed to such natural disasters have never been fewer, thanks to modern technology and infrastructure.

Arctic sea ice has recently melted more in summer than it used to in the 1980s, but Antarctic sea ice has increased, and Antarctica is gaining land-based ice, according to a new study by NASA scientists published in the Journal of Glaciology. Sea level continues its centuries-long slow rise—about a foot a century—with no sign of recent acceleration.
