The
old joke about how an optimist and a pessimist can see the same glass of water
and say different things about it applies to a lot of things. The optimist who says it's half full brings a
different attitude to the same physical facts that the half-empty pessimist
looks at, but draws different conclusions from them.
Climate
change and the effects of rising carbon dioxide levels on global temperatures
and weather have led to a widespread attitude of despair, according to Matt
Frost, a policy analyst who recently published an article called "After
Climate Despair" in The New Atlantis. His
approach to climate change is neither denial nor agreement with the prevailing consensus
of certain political groups that we are staring doom in the face. Instead, it's a good example of how attitude
can make a big difference in the interpretation of facts.
The
standard high-level public-policy take on climate change goes something like
this. Humankind has foolishly burned
itself into an ongoing crisis that will, if not averted by radical and
draconian imposition of fossil-fuel bans and restrictions, lead to the downfall
of civilization and the destruction of the ecosphere. The only viable solution is the imposition of
a global austerity plan that rolls back global energy use to a level comparable
to what it was back somewhere in the 19th century, and even then, it will take
decades or centuries before any notable improvement will come. The fact that the major world governments
have not fallen into line and cooperated with this solution is cause for despair,
a despair akin to that which relatives of a hopeless drug addict feel when they
try to intervene, but the addict goes right on shooting up until he overdoses.
Frost
begins by distinguishing between the main factor in climate change—namely, the
burning of fossil fuels that increase the levels of carbon dioxide in the atmosphere—and
the fact that energy abundance and growth is necessary for human flourishing in
today's world. Perhaps the key insight
he brings in his set of proposals is that we should look on carbon dioxide
emissions not as a horror to be avoided at all cost, nor as totally innocuous,
but as waste, similar to sewage, scrap iron, or other byproducts of industrial
activity that engineers have learned how
to deal with in the past.
He
examines several proposed solutions that would reduce global warming, and
discards them for various reasons.
Switching to burning wood instead of coal and oil and gas is impractical
because it would require huge amounts of farmland that we don't have, or that
we need already for food. Throwing tons
of sulfur dioxide into the atmosphere to reduce the influx of infrared
radiation, while possibly reducing global temperatures, might screw up the
ecosphere even worse than it is now. The
basic approach he recommends is one of energy abundance, and we have plenty of
knowhow to bring that about with only minor changes in directions that we're
already pursuing.
For
one thing, nuclear energy is sadly underutilized in most countries, a notable
exception being France. While nuclear
waste is a problem, it's a localized manageable problem and doesn't
automatically escape into the air and cause climate change. Treating carbon dioxide emissions as a waste
product similar to sewage would allow the sensible, deliberate implementation
of regulations backed by engineering solutions that might lead to sequestering
or reuse of the gas, which after all, given sufficient energy, can be
reconverted into fuel again. While such
processes are done only on a pilot scale today, if we realize that lower energy
prices would make them more practical, we could break through the barrier of
despair and do something about carbon in the atmosphere by means of the very
energy that the present despairing attitude would have us say good-by to.
Another
good point that Frost makes is that these sorts of things can be done on a
small scale: a solar installation here,
a carbon-abatement plant there. These
sorts of things don't need any giant global bureaucracy to administer. While dealing with the present and future
consequences of climate change will present challenges that are in some ways
unique, throwing up our hands and giving up on civilization is not the
answer. In a sense, engineering got us
into the situation we're in today, and as long as we believe engineering can
help us deal with the consequential problems, we have a handle on possible paths
to solutions.
As
I read Frost's article, it occurred to me that some of what he's proposing has
already taken place. Watt for watt,
burning natural gas for energy produces less carbon dioxide emission than
burning coal. An early worrier about
climate change in, say, 1990, might have come out in favor of a massive
government-directed effort to shut down all our cheaply operating coal-fired
power plants and force them to burn expensive natural gas, at the price of
raising electricity prices by 300% and causing a recession.
That
didn't happen, but something else did that bureaucrats didn't expect. The petroleum industry developed fracking and
a spectrum of other technologies that led to the exploitation of abundant
natural-gas reserves in old oil fields, which has sent natural gas prices
plummeting and shuttered coal-fired plants, not because they're illegal, but
because they're unprofitable. As a
result, the U. S. power-generation industry is now more carbon-friendly than it
used to be as a whole, all without heavy-handed government intervention.
We
can't rely on the market to pull this kind of benign trick all the time, but
it's an example of how a can-do optimistic attitude toward a difficult
situation can lead to surprisingly good results. Perhaps not all of Frost's specific policy
proposals will find favor in the halls of power, but what I hope people do take
from him is his attitude. In the Roman
Catholic catalog of sins, despair is the one unforgivable sin, because by definition,
if you give up hope of salvation, you can't be saved. The principle has applications beyond theology. If we decide that the only way to reduce
carbon emissions is to achieve the politically impossible, well, by definition,
that's not going to happen. Frost's
advice is to look at the wide array of possible and even local things we can
do, and work on those.

resumé I learned that he has five children, and is thus invested in seeing the
future turn out better than it might.
