The hurricane that struck Louisiana and Mississippi on Monday was nicknamed Katrina by the National Weather Service. Its real name is global warming.
When the year began with a 2-foot snowfall in Los Angeles, the cause was global warming.
When winds of 124 miles an hour shut down nuclear plants in Scandinavia and cut power to hundreds of thousands of people in Ireland and Britain, the driver was global warming.
When a severe drought in the Midwest dropped water levels in the Missouri River to their lowest on record earlier this summer, the reason was global warming.
In July, when the worst drought on record triggered wildfires in Spain and Portugal and left water levels in France at their lowest in 30 years, the explanation was global warming.
When a lethal heat wave in Arizona killed more than 20 people in one week, the culprit was global warming.
And when the Indian city of Mumbai received 37 inches of rain in one day - killing 1,000 people and disrupting the lives of 20 million others - the villain was global warming.
As the atmosphere warms, it generates longer droughts, more intense downpours, more frequent heat waves, and more severe storms.
Although Katrina began as a relatively small hurricane that glanced off southern Florida, it was supercharged with extraordinary intensity by the high sea surface temperatures in the Gulf of Mexico.
The consequences are as heartbreaking as they are terrifying.
Unfortunately, few people in America know the real name of Hurricane Katrina because the coal and oil industries have spent millions of dollars to keep the public in doubt about the issue.
The reason is simple: To allow the climate to stabilize requires humanity to cut its use of coal and oil by 70 percent. That, of course, threatens the survival of one of the largest commercial enterprises in history.
