Cory Doctorow's column in this month's LOCUS, whether you fully agree with his view of the global situation or not, displays an impressive deployment of an extended metaphor:
The SwerveThis essay compares the climate change problem to a speeding bus about to crash off a cliff. Should we grab the wheel from the driver and swerve off the road at high speed, even at the risk of a disastrous crash? As you'll notice a few sentences into the essay, Doctorow holds an extreme view of the inevitable severity of climate change. Yet he ends with an ultimately (though guardedly) optimistic conclusion that total catastrophe can still be avoided. But, in his opinion, we've come too far already to evade the damage inherent in the swerve.
This is how he describes the scenario at the beginning of the article:
"We’re all trapped on a bus. The bus is barreling towards a cliff. Beyond the cliff is a canyon plunge any of us will be lucky to survive. Even if we survive, none of us know how we’ll climb out of that deep canyon. Some of us want to yank the wheel. The bus is going so fast that yanking the wheel could cause the bus to roll. There might be some broken bones. There might be worse than broken bones. The driver won’t yank the wheel."
In Doctorow's formatting, however, each of those sentences sits on a line by itself. Arranged that way, the opening can't fail to grab a reader's attention. The alarm and urgency of his message come through loud and clear. He goes on to condemn climate change denial, express his disapproval of "incrementalism," and discuss some of the public responses to the problem, positive and negative, that have been proposed or attempted so far.
It seems to me that one significant reason why many people don't believe we're about to drive off a cliff is that climate degradation is a "slow catastrophe." It doesn't evoke immediate alarm like an asteroid on a collision course with Earth. The effects of global climate shifts sneak up on us over a span of years or decades. So those who think we still have plenty of time to deal with the crisis aren't necessarily greedy, callous, or oblivious.
Doctorow estimates that in 1992 we still had the option of "building a bridge" across the canyon. By now, he asserts, we've lost the opportunity of "averting the disaster" and instead must focus on "surviving the disaster." Still, he comes to an optimistic conclusion, for a certain value of "optimistic." He describes the potential "happy ending" in terms of the extended metaphor this way:
"We’ll swerve. The bus will roll. It will hurt. It will be terrible. But we won’t be dead on canyon floor. We’ll fix the bus. We’ll make it better. We’ll get it back on its wheels. We’ll get a better driver, and a better destination."
