Introduction
As
climate change becomes inevitable, the public, government, and scientific community will begin to consider the idea of altering the climate in order to prevent further
change. These processes and projects are known as
geo-engineering. They center on the
principle that if we can not muster the social will or technological ingenuity
to prevent a changing climate we will have to reengineer nature to prevent
climate change’s worst extremes, or reverse the process. There are many different ideas on the table,
all of which should be viewed skeptically given the complexity of our ecological
systems and the scale of change altering the Earth’s climate implies. Currently, there are tests being proposed and
postponed in the UK
that would use an enormous hose to inject sulfates into the stratosphere,
cooling the planet. Such projects bring
with them a host of international governance issues. All geo-engineering projects propose actions
with global implications and their effects will traverse national
boundaries. Some projects may indirectly
harm other nations; which raises the question of who will be held responsible
when that happens. What institutions, if
any, will have authority over geo-engineering?
Will there be an international decision making and approval process or
will nations act unilaterally? Without
these questions answered the prospects for a successful project are slim, or
conversely, the chances of an ill-conceived project are greater.
As
a result of the complexity of Earth’s climate systems geo-engineering is a
risky and controversial subject; however it can easily be viewed as a last
second fix. Thus it is incredibly
important to understand the issues at stake. To do this I will be discussing multiple proposed
geo-engineering fixes to climate change and their possible ecological, political, and legal
impacts. Outside of that I will be
reviewing the aforementioned sulfur injection project, the SPICE project, and
the governance and approval mechanisms that are currently being used to
regulate it. Geo-engineering is a
dangerous path which humanity seems headed for. Adequate safeguards against reckless project
implementation are not in place. As a
result, international regimes need to be formed to ensure that anything
implemented does not create a cycle of projects of ever increasing scale.
