This week the issue of global warming caused embarrassing problems for Marco Rubio as the Republican Senator from Miami rolled out his unofficial entry into the 2016 presidential race. Sorry, but I couldn’t help noticing. Although I am not a Republican and no longer live in Florida, I once owned a home on the Intracoastal Waterway near Palm Beach. During hurricanes, our little beach disappeared along with half of our yard. A two-foot sea rise will leave storm water at the new owner’s front door. Another two feet will make the house, along with thousands of other coastal homes, uninhabitable. So I’ve been scratching my head over the confused case Marco Rubio tried to articulate for doing nothing to mitigate global warming—an odd position for any elected official from South Florida to take. Oops! There goes Miami Beach!

As usual, John Steinbeck helped me think. Because his science book Sea of Cortez is also political and philosophical, I turned to the writer’s “Leisurely Journal of Travel and Research” in the Gulf of California to help me understand politicians like Marco Rubio who (1) deride global warming data, (2) deny that fossil-fuel use is a factor, or (3) insist that it’s too late to turn back, so what the hell! During the course of speeches and interviews in New Hampshire and elsewhere, Marco Rubio denied global warming so often and so recklessly that he became the butt of a Wednesday night Stephen Colbert Show “F*ck It!” segment. What part of Rubio’s brain shut down when he opened his campaign for president? Three observations made by John Steinbeck on the biology of belief and behavior in Chapter 14 of Sea of Cortez provided clarity, but little comfort, about Marco Rubio’s recent statements regarding global warming. Hold the applause. They are nothing to laugh about.
1. Forget simplistic causation. Find provable relationships and prepare for complexity.
Sea of Cortez starts with first principles. From microbes to mankind, variation in nature is a universal principle; causative relationships are complex and outcomes aren’t always predictable. But worldwide climate disruption is a particularly violent variation with measurable relationships and very clear consequences. Denying the significance of man-made carbon emissions in accelerating global warming by implying, as Marco Rubio and others do, that . . . well, shit happens . . . is like letting a drunk drive on the theory that other things can go wrong too, so what’s the big deal? Ignition failure, bad brakes, lousy weather, all contribute to accidents on the road. But driving while drunk, like loading the atmosphere with pollutants, foolishly increases the severity and consequences of co-contributing factors.

“Sometimes,” John Steinbeck would have agreed, “shit just happens.” But try taking that excuse to court and see what happens there—if you survive the wreck you caused. Steinbeck was a Darwinian who tried not to judge, but deadly driving while drunk has been described by those who are less forgiving as a form of natural self-selection for stupid individuals. Unlike solitary drinking, however, global warming denial is a social disease. Following the dimwitted herd of reality-deniers, like lemmings, over the looming climate cliff? That takes systematic self-delusion and self-styled leaders like Marco Rubio. How do they operate? John Steinbeck had a theory.
2. Reality-denial is a form of adolescent wish-fulfillment. It’s most dangerous in a mob motivated by a self-appointed leader.
Sea of Cortez—co-authored with Steinbeck’s friend and collaborator, the marine biologist Ed Ricketts—develops many of the ideas Steinbeck expressed in the fiction he wrote before 1940. His 1936 novel In Dubious Battle, for example, dramatized the murderous behavior of opposing mobs, behavior worse than anything within the capacity of their individual constituents. Steinbeck’s characterization of politically-driven leaders like Mac, the novel’s Communist labor-organizer, is particularly disturbing, even today. Sea of Cortez develops both of these core ideas—the behavior of mob members and the psychology of mob leaders—using biological terms that help explain Marco Rubio and his position on global warming.

Like Steinbeck’s metaphorical ameba in Sea of Cortez, Mac the Communist and Marco Rubio the Republican are political pseudo-pods who detect a mass-wish within their followers and press toward its fulfillment: “We are directly leading this great procession, our leadership ‘causes’ all the rest of the population to move this way, the mass follows the path we blaze.” But one difference between Mac and Marco Rubio, worth noting, was apparent in this week’s events. Steinbeck’s labor agitator was a tough guy with street smarts who stayed on-message; Marco Rubio manages to look as unfixed and immature as he sounds. In right-wing global warming politics, Rick Perry—no George Bush, and take that as a compliment—seems statesmanlike by comparison. Oops! I meant Department of Education!
3. Extinction is possible. Double extinction.
John Steinbeck read encyclopedically, and in Sea of Cortez he explains what he calls “the criterion of validity in the handling of data” by citing an example from an article on ecology in the 14th edition of Encyclopaedia Britannica. It concerns the extermination of a certain species of hawk that preyed on the willow grouse, a game bird in Norway. Failing to note the presence of the parasitical disease coccidiosis in the country’s grouse population, the Norwegians systematically eradicated the predator that kept the infection under control by killing off weaker birds affected by the disease. The result was double extinction—hawk and grouse—caused by uninformed human behavior.

Like Steinbeck, I loved college biology, and the biology department at Wake Forest was very good. My freshman professor, a John Steinbeck-Ed Ricketts type named Ralph Amen, introduced us to an idea that makes Marco Rubio’s anti-global warming demagoguery more than a little scary 50 years later. “Imagine,” Dr. Amen suggested, “that the earth is an organism, Gaia, with a cancer—the human species, overpopulating and over-polluting its host. What is the likely outcome of this infection for Gaia and for mankind?” A question in the spirit of Sea of Cortez, which on reflection I’m certain he had read.
‘Imagine,’ Dr. Amen suggested, ‘that the earth is an organism, Gaia, with a cancer—the human species, overpopulating and over-polluting its host. What is the likely outcome of this infection for Gaia and for mankind?’
John Steinbeck, a one-world ecologist even further ahead of his time than my old teacher, would have answered, “things could go either way.” The cancer might kill the host or the host eradicate the cancer. But global warming presents a third possibility—double extinction. Now imagine that Marco Rubio is a soft, squishy symptom of global warming denial, a terminal disease. Then reread John Steinbeck’s Sea of Cortez as I just did. Reality-based thinking is our first step toward a cure, although under a president like Marco Rubio it could also be our last. Oops! There we go—along with the planet! How in the world did we let that happen?
