At the presidential candidate debate last night, Beto O'Rourke said out loud what almost all climatologists and other thinking people know - There is no hope for preventing or stopping the progression of climate change. I copy below an article from The New Yorker which expresses this very well.
“There is infinite hope,” Kafka tells us, “only not for us.”
This is a fittingly mystical epigram from a writer whose characters strive for
ostensibly reachable goals and, tragically or amusingly, never manage to get
any closer to them. But it seems to me, in our rapidly darkening world, that
the converse of Kafka’s quip is equally true: There is no hope, except for us.
I’m talking,
of course, about climate change. The struggle to rein in global carbon
emissions and keep the planet from melting down has the feel of Kafka’s
fiction. The goal has been clear for thirty years, and despite earnest efforts
we’ve made essentially no progress toward reaching it. Today, the scientific
evidence verges on irrefutable. If you’re younger than sixty, you have a good
chance of witnessing the radical destabilization
of life on earth—massive crop failures, apocalyptic fires, imploding
economies, epic flooding, hundreds of millions of refugees fleeing regions made
uninhabitable by extreme heat or permanent drought. If you’re under thirty,
you’re all but guaranteed to witness it.
If you care
about the planet, and about the people and animals who live on it, there are
two ways to think about this. You can keep on hoping that catastrophe is
preventable, and feel ever more frustrated or enraged by the world’s inaction.
Or you can accept that disaster is coming, and begin to rethink what it means
to have hope.
Even at this
late date, expressions of unrealistic hope continue to abound. Hardly a day
seems to pass without my reading that it’s time to “roll up our sleeves” and
“save the planet”; that the problem of climate change can be “solved” if we
summon the collective will. Although this message was probably still true in
1988, when the science became fully clear, we’ve emitted as much atmospheric
carbon in the past thirty years as we did in the previous two centuries of
industrialization. The facts have changed, but somehow the message stays the
same.
Psychologically,
this denial makes sense. Despite the outrageous fact that I’ll soon be dead
forever, I live in the present, not the future. Given a choice between an
alarming abstraction (death) and the reassuring evidence of my senses
(breakfast!), my mind prefers to focus on the latter. The planet, too, is still
marvelously intact, still basically normal—seasons changing, another election
year coming, new comedies on Netflix—and its impending collapse is even harder
to wrap my mind around than death. Other kinds of apocalypse, whether religious
or thermonuclear or asteroidal, at least have the binary neatness of dying: one
moment the world is there, the next moment it’s gone forever. Climate
apocalypse, by contrast, is messy. It will take the form of increasingly severe
crises compounding chaotically until civilization begins to fray. Things will
get very bad, but maybe not too soon, and maybe not for everyone. Maybe not for
me.
Some of the
denial, however, is more willful. The evil of the Republican Party’s position
on climate science is well known, but denial is entrenched in progressive
politics, too, or at least in its rhetoric. The Green New
Deal, the blueprint for some of the most substantial proposals put
forth on the issue, is still framed as our last chance to avert catastrophe and
save the planet, by way of gargantuan renewable-energy projects. Many of the
groups that support those proposals deploy the language of “stopping” climate
change, or imply that there’s still time to prevent it. Unlike the political
right, the left prides itself on listening to climate scientists, who do indeed
allow that catastrophe is theoretically avertable. But not everyone seems to be
listening carefully. The stress falls on the word theoretically.
Our atmosphere
and oceans can absorb only so much heat before climate change, intensified by
various feedback loops, spins completely out of control. The consensus among
scientists and policy-makers is that we’ll pass this point of no return if the
global mean temperature rises by more than two degrees Celsius (maybe a little
more, but also maybe a little less). The I.P.C.C.—the Intergovernmental Panel
on Climate Change—tells us that, to limit the rise to less than two degrees, we
not only need to reverse the trend of the past three decades. We need to
approach zero net emissions, globally, in the next three decades.
This is, to
say the least, a tall order. It also assumes that you trust the I.P.C.C.’s
calculations. New research, described last month in Scientific
American, demonstrates that climate scientists, far from
exaggerating the threat of climate change, have underestimated its pace and
severity. To project the rise in the global mean temperature, scientists rely
on complicated atmospheric modelling. They take a host of variables and run
them through supercomputers to generate, say, ten thousand different
simulations for the coming century, in order to make a “best” prediction of the
rise in temperature. When a scientist predicts a rise of two degrees Celsius,
she’s merely naming a number about which she’s very confident: the rise will be at least two
degrees. The rise might, in fact, be far higher.
As a non-scientist, I do my own kind of
modelling. I run various future scenarios through my brain, apply the
constraints of human psychology and political reality, take note of the
relentless rise in global energy consumption (thus far, the carbon savings
provided by renewable energy have been more than offset by consumer
demand), and count the scenarios in which collective action averts catastrophe.
The scenarios, which I draw from the prescriptions of policy-makers and
activists, share certain necessary conditions. The first condition is that
every one of the world’s major polluting countries institute draconian
conservation measures, shut down much of its energy and transportation
infrastructure, and completely retool its economy. According to a recent paper
in Nature, the carbon emissions from existing global
infrastructure, if operated through its normal lifetime, will exceed our entire
emissions “allowance”—the further gigatons of carbon that can be released
without crossing the threshold of catastrophe. (This estimate does not include
the thousands of new energy and transportation projects already planned or
under construction.) To stay within that allowance, a top-down intervention
needs to happen not only in every country but throughout every
country. Making New York City a green utopia will not avail if Texans keep
pumping oil and driving pickup trucks.
