In
the previous entry, “In
a Glass Dome,” we considered the problem of accepting the
simpler scientific explanation for something when that acceptance
requires a change in world view. Perhaps
global warming as
a result of human activity
is such
an
explanation. It
may not seem as momentous as accepting that the earth moves around
the sun, but it is akin to it.

The
opposite of the humility-based
argument is the hubris-based
argument, expressed by those
confident that humans’ godlike ingenuity can
increase the capacity of the
world regardless of what happens.
They
point to how the Green
Revolution, resulting from an array of agricultural innovations
that replaced traditional farming methods, radically increased the
world-wide crop yield. The increase in food after
World War II was almost
miraculous, and some places
where starvation was endemic were
eventually able
to produce surpluses. Those
who feel that the potential for innovation is unlimited are not
intimidated by the warming of the earth.
Of course the Catch-22 of
that position is that since we have not been innovative
enough to to reduce the rate
at which the earth is warming as a result of our other innovations,
why do we think we can solve the problems resulting from global warming when we could
not deal with its causes? Even
the Green Revolution, with its heavy reliance on chemicals, fossil
fuel, mono-culture, and massive irrigation, is itself becoming a
problem as the cheap food it has been able to yield has wiped out more resilient, low-impact, local agricultural practices. Now the
climate disruptions created by global warming--the shifts in seasonal
patterns, droughts
and floods, and violent weather events—are
putting stress on industrial agricultural practices that
helped produce the warming. It is a
gamble to go on in an
unsustainable manner depending
on some unspecified, future breakthrough to save us, to think of the
earth as an infinitely open system.
In 1966, the economist Kenneth
Boulding argued we should treat earth as a closed system and
understand that we need to be as careful of what we are doing as we
would be on a spaceship. Buckminister Fuller warned in Operating
Manual for Spaceship
Earth (1968) that fossil fuel is a finite resource developed
over millions of years, a resource we should treat as temporary,
something we should use to develop renewable sources of energy.
NASA’s Big Blue Marble composite photograph taken by Apollo 17 in
1975 shows the globe of earth as a whole surrounded by the blackness
of space. Though we can travel over the continuous surface of the
earth and never reach an edge, this image shows that sharp border
between the earth and the blackness surrounding it: our earth is a
small finite spot in a huge hostile universe.
In 1988 when James
Hanson of the Goddard Institute for Space Studies testified before
the US Congress about global warming, some Americans began to take
notice. People of my generation grew up with the fear of a nuclear
apocalypse and were used to the idea that people could make the earth
unlivable. However, the Mutually Assured Destruction approach to
world peace (appropriate acronym, MAD) involved devices whose sole
purpose was to destroy, so all we needed to do was not turn them on.
But global warming is different because it is a byproduct of living
well, the dark side of progress. In order to stop the destruction we
must do more than not turn things on; we must turn things off, and to
do that we must change the way we live at a fundamental level.
Just
as Galileo’s observations and analysis cemented Copernicus’s
heliocentric explanation in place, the
subsequent
work of the
Intergovernmental Panel on
Climate Change has
forced us to accept that our actions are affecting the earth’s
viability for humans. Global
warming
reminds us that in deciding
what to do, we
must not ask only “Can we
do it?” but we must also
ask “Should
we do it?” The first is a
scientific question; the second uses scientifically derived
information, but it is an ethical question.
We must rediscover that the universe
does not revolve around us humans, that the earth was not made for
us, but that we have evolved and thrived in the earth’s
environment, and if that environment changes too much, our species
will
die out.
Once
again accepting scientific results disrupts comforting
religious and
humanistic world views. To
extend the survival of our
species, we must accept the
possibility of its death.
