Engineering the Future: Geoengineering

Posted: May 23, 2013

Geoengineering has an image problem. Some proposed geoengineering
projects, such as space mirrors or cloud seeding, seem like they come
from the pages of a science fiction novel. Those who propose these
projects are treated with belittling rhetoric. Other projects face a
different type of imaging problem; the project’s proponents are
accused of having vague or unspecified goals and timelines. Such
projects are summarily dismissed as being idealistic, out of touch or
nebulous.

It is easy for a proponent of geoengineering to become disheartened by
the huge task of presenting geoengineering as both an affordable and
ethical choice. I have selected some of the most common criticisms
about geoengineering and presented possible counter arguments that
focus on the benefits of a geoengineering project.

One criticism of geoengineering projects that proponents are nebulous
or vague in describing the scientific aim of the project. I this
criticism read as what problem is the project trying to counter and
why is it this a problem? This question is important to geoengineering
advocates because it demonstrates that the listener may not understand
the scientific purpose of the project.

A geoeningeering project provides an opportunity for increasing the
public’s interest in science. Once interest has been generated, public
debates about the merits or hazards of a geoengineering project can be
discussed by the public. Such a debate would provide an opportunity
for geoengineering advocates and detractors to present their cases to
the public. The debate may delay the project’s implementation, but
such a debate acknowledges the role public as a participant in
democracy and science policy.

Another common question critics of geoengineering ask is how long will
the project last and when will it be finished? I will concede that
critics have a point. When discussing a project that will change the
surface of plant, it is important to clarify the period of time under
discussion and what specific, time related words mean in the context
of the argument. Does immediately mean 10 years or tomorrow? Will
current generations reap any benefit from the project?

Assuming a common vocabulary is reached, the long timescale required
of a geoengineering project has numerous advantages. One could argue
that any project that took greater than ten years to complete would
require a sizable investments in the form of labor and finances. The
labor required for the project would reduce unemployment numbers for
certain sectors of the economy. Science and engineering sectors would
see a drop in unemployment and would related technical fields. Manual
labor may see a drop, but only when construction was underway.

The financial investment in a geoengineering project would also
benefit a country’s economy. A large scale geoengineering project
would require the development of new technologies and industries.
These industries would contribute to lowering the unemployment rate.
New industries would put a country on the cutting edge of
technological development.

How big of a project will this be and who will manage the construction
phase? The answer depends on the scale and type of the proposed
geoengineering project. A small scale reforestation project could be
managed by state and local officials. A large scale project, such as
cloud reseeding or carbon sequestration, could be managed by federal
and state level officials. The option to contract the work to private
corporations would exist at every level. Geoengineering projects that
required international cooperation present unqiue geopolitical
challenges, which will be mentioned later.

Such questions allow advocates to show that a range of viable
geoengineering projects exist. Sample projects include space based
projects, land-management projects, cloud seeding projects, and
biological processes. A projects can be selected and modified to meet
existing environmental, financial and political conditions of the
state or nation. As an aside, the wide range of choices automatically
disproves the extremely dichotomous portrayals of geoengineering
projects as fantastical mega-projects or unrealistic demands on
resources..

What if this project does not work and the underlying environmental
problem still exists? There are two answers to this question. The
first answer concerns how the project’s timescale was presented. The
project’s designers may have underestimated the required timescale for
the project to take effect or the public is expecting the effect to
occur rapidly. Another answer is that the project was not intended to
address the cause of the environmental problem and is only treating
the outcome.

For sake of analogy, imagine you were diagnosed with diabetes. You are
taking insulin but have not altered your diet to help control your
blood sugar. In this analogy, the geoengineering project is the
insulin. It helps treat the effects of diabetes but it does replace
proper diet and exercise. Critics are right in saying that while the
geoengineering project may perform the task it was intended to but it
is not addressing the underlying problem.

The counter argument to that claim is that like insulin, the
geoengineering project is not necessarily intended as a cure. The
project can help control or migrate the problem, but it is not
intended to address the root of the problem.

A geoengineering project could work in concern with other
environmental policies that aimed at limiting atmospheric pollutants.
The aim of the policies would be to reduce the number of pollutants
being added to the atmosphere. The geoengineering project removes the
existing pollutants.

There is an additional international public relations hurdle that
geoengineering needs to overcome. This is the fear of a geoengineering
project being weaponization. A nation that could alter the climate or
geography of their opponents territory would hold a distinct strategic
advantage. The specter of a climatic arms race hangs in the distance,
as nations vie for ever stronger climate based weapons to counter
supposed threats.

How do we overcome this fear? One option is to prohibit any one nation
from building a space based geoengineering such as a solar mirror.
This constrain would essentially force international cooperation, as
no single nation would have direct control over the project. It is
possible that this solution would occur by default if we assume that
no single could afford to build a space based project on their own.

Another solution is the fear of mutually assured destruction. Much
like a nation’s nuclear arsenal, a rational nation would be hesitant
to use climate based weapons for the fear of the opposing side would
retaliate with stronger weapons. Additionally, the effects of a
climate based weapon would not be contained to one nation.
Essentially, using a climate based weapon would carry the inherent
risk of damaging your nation’s environment.

Understanding the motives behind criticisms of geoengineering projects
allows for advocates of such projects to correct the public image of
geoengineering. I attribute the majority of the above criticsims to
the fact that humanity has never executed a geoengineering project on
such a grand scale. By focusing on the wide range of geoengineering
projects that can be implemented and how these projects would work
with other environmental measures, geoengineering becomes less
nebulous or fantastic and more plausible.
