A place I can put my thoughts on science, teaching and the human condition, and also occasionally attempt to influence policy makers (lots of luck!).

What if We Stop Pretending - The climate apocalypse is coming. To prevent it, we need to admit that we cant prevent it. • By Jonathan Franzen.
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.
The actions
taken by these countries must also be the right ones. Vast sums of government
money must be spent without wasting it and without lining the wrong pockets.
Here it’s useful to recall the Kafkaesque joke of the European Union’s biofuel
mandate, which served to accelerate the deforestation of Indonesia for palm-oil
plantations, and the American subsidy of ethanol fuel, which turned out to
benefit no one but corn farmers.
Finally,
overwhelming numbers of human beings, including millions of government-hating
Americans, need to accept high taxes and severe curtailment of their familiar
life styles without revolting. They must accept the reality of climate change
and have faith in the extreme measures taken to combat it. They can’t dismiss
news they dislike as fake. They have to set aside nationalism and class and
racial resentments. They have to make sacrifices for distant threatened nations
and distant future generations. They have to be permanently terrified by hotter
summers and more frequent natural disasters, rather than just getting used to
them. Every day, instead of thinking about breakfast, they have to think about
death.
Call me a pessimist or call me a humanist, but I
don’t see human nature fundamentally changing anytime soon. I can run ten
thousand scenarios through my model, and in not one of them do I see the
two-degree target being met.
To judge from
recent opinion polls, which show that a majority of Americans (many of them
Republican) are pessimistic about the planet’s future, and from the success of
a book like David Wallace-Wells’s harrowing “The
Uninhabitable Earth,” which was released this year, I’m not alone in
having reached this conclusion. But there continues to be a reluctance to
broadcast it. Some climate activists argue that if we publicly admit that the
problem can’t be solved, it will discourage people from taking any ameliorative
action at all. This seems to me not only a patronizing calculation but an
ineffectual one, given how little progress we have to show for it to date. The
activists who make it remind me of the religious leaders who fear that, without
the promise of eternal salvation, people won’t bother to behave well. In my
experience, nonbelievers are no less loving of their neighbors than believers.
And so I wonder what might happen if, instead of denying reality, we told
ourselves the truth.
First of all,
even if we can no longer hope to be saved from two degrees of warming, there’s
still a strong practical and ethical case for reducing carbon emissions. In the
long run, it probably makes no difference how badly we overshoot two degrees;
once the point of no return is passed, the world will become self-transforming.
In the shorter term, however, half measures are better than no measures.
Halfway cutting our emissions would make the immediate effects of warming
somewhat less severe, and it would somewhat postpone the point of no return.
The most terrifying thing about climate change is the speed at which it’s
advancing, the almost monthly shattering of temperature records. If collective
action resulted in just one fewer devastating hurricane, just a few extra years
of relative stability, it would be a goal worth pursuing.
In fact, it
would be worth pursuing even if it had no effect at all. To fail to conserve a
finite resource when conservation measures are available, to needlessly add
carbon to the atmosphere when we know very well what carbon is doing to it, is
simply wrong. Although the actions of one individual have zero effect on the
climate, this doesn’t mean that they’re meaningless. Each of us has an ethical
choice to make. During the Protestant Reformation, when “end times” was merely
an idea, not the horribly concrete thing it is today, a key doctrinal question
was whether you should perform good works because it will get you into Heaven,
or whether you should perform them simply because they’re good—because, while
Heaven is a question mark, you know that this world would be better
if everyone performed them. I can respect the planet, and care about the people
with whom I share it, without believing that it will save me.
More than
that, a false hope of salvation can be actively harmful. If you persist in
believing that catastrophe can be averted, you commit yourself to tackling a
problem so immense that it needs to be everyone’s overriding priority forever.
One result, weirdly, is a kind of complacency: by voting for green
candidates, riding a bicycle to work, avoiding air travel, you might feel that
you’ve done everything you can for the only thing worth doing. Whereas, if you
accept the reality that the planet will soon overheat to the point of
threatening civilization, there’s a whole lot more you should be doing.
Our resources
aren’t infinite. Even if we invest much of them in a longest-shot gamble,
reducing carbon emissions in the hope that it will save us, it’s unwise to
invest all of them. Every billion dollars spent on high-speed trains, which may
or may not be suitable for North America, is a billion not banked for disaster
preparedness, reparations to inundated countries, or future humanitarian
relief. Every renewable-energy mega-project that destroys a living
ecosystem—the “green” energy development now occurring in Kenya’s
national parks, the giant hydroelectric projects in Brazil, the
construction of solar farms in open spaces, rather than in settled areas—erodes
the resilience of a natural world already fighting for its life. Soil and water
depletion, overuse of pesticides, the devastation of world fisheries—collective
will is needed for these problems, too, and, unlike the problem of carbon,
they’re within our power to solve. As a bonus, many low-tech conservation
actions (restoring forests, preserving grasslands, eating less meat) can reduce
our carbon footprint as effectively as massive industrial changes.
All-out war on
climate change made sense only as long as it was winnable. Once you accept that
we’ve lost it, other kinds of action take on greater meaning. Preparing for
fires and floods and refugees is a directly pertinent example. But the
impending catastrophe heightens the urgency of almost any world-improving
action. In times of increasing chaos, people seek protection in tribalism and
armed force, rather than in the rule of law, and our best defense against this
kind of dystopia is to maintain functioning democracies, functioning legal
systems, functioning communities. In this respect, any movement toward a more
just and civil society can now be considered a meaningful climate action.
Securing fair elections is a climate action. Combatting extreme wealth
inequality is a climate action. Shutting down the hate machines on social media
is a climate action. Instituting humane immigration policy, advocating for
racial and gender equality, promoting respect for laws and their enforcement,
supporting a free and independent press, ridding the country of assault
weapons—these are all meaningful climate actions. To survive rising
temperatures, every system, whether of the natural world or of the human world,
will need to be as strong and healthy as we can make it.
And then
there’s the matter of hope. If your hope for the future depends on a wildly
optimistic scenario, what will you do ten years from now, when the scenario
becomes unworkable even in theory? Give up on the planet entirely? To borrow
from the advice of financial planners, I might suggest a more balanced
portfolio of hopes, some of them longer-term, most of them shorter. It’s fine
to struggle against the constraints of human nature, hoping to mitigate the
worst of what’s to come, but it’s just as important to fight smaller, more
local battles that you have some realistic hope of winning. Keep doing the
right thing for the planet, yes, but also keep trying to save what you love specifically—a
community, an institution, a wild place, a species that’s in trouble—and take
heart in your small successes. Any good thing you do now is arguably a hedge
against the hotter future, but the really meaningful thing is that it’s good
today. As long as you have something to love, you have something to hope for.
In Santa Cruz,
where I live, there’s an organization called the Homeless
Garden Project. On a small working farm at the west end of town, it
offers employment, training, support, and a sense of community to members of
the city’s homeless population. It can’t “solve” the problem of homelessness,
but it’s been changing lives, one at a time, for nearly thirty years.
Supporting itself in part by selling organic produce, it contributes more
broadly to a revolution in how we think about people in need, the land we
depend on, and the natural world around us. In the summer, as a member of its
C.S.A. program, I enjoy its kale and strawberries, and in the fall, because the
soil is alive and uncontaminated, small migratory birds find sustenance in its
furrows.
There may come a
time, sooner than any of us likes to think, when the systems of industrial
agriculture and global trade break down and homeless people outnumber people
with homes. At that point, traditional local farming and strong communities
will no longer just be liberal buzzwords. Kindness to neighbors and respect for
the land—nurturing healthy soil, wisely managing water, caring for pollinators—will
be essential in a crisis and in whatever society survives it. A project like
the Homeless Garden offers me the hope that the future, while undoubtedly worse
than the present, might also, in some ways, be better. Most of all, though, it
gives me hope for tod
