at it

On
January 19, 2011, I
got a phone call from two men who told me they were consultants for
the CIA.
Roger Lueken and Michael Canes, analysts for the Logistics Management
Institute, asked, among other things, “If another country were
trying to control our climate, would we be able to detect it?”
I
told them that I thought we could, because if a cloud in the
stratosphere were created (the most commonly proposed method of
control) that was thick enough, large enough, and long-lasting enough
to change the amount of energy reaching Earth, we could certainly see
it with the same ground-based and satellite instruments we use to
measure stratospheric clouds from volcanic eruptions. If, on the
other hand, low
clouds were being brightened over the ocean (another
suggested means of cooling the climate), we could see telltale
patterns in the tops of the clouds with satellite photos. And it
would also be easy to observe aeroplanes or ships injecting gases or
particles into the atmosphere.
At
the same time, I wondered whether they also wanted to know if others
would know about it, if the CIA was controlling the world’s
climate. Given that the CIA is a major sponsor of the recently
released US
National Academy of Sciences (NAS) reports on geoengineering (which
they have renamed “climate intervention”), the question arises as
to the possible interest of the CIA in global climate control.
Let
me be clear. I completely agree with all the NAS findings. Global
warming is real and is being caused by humans, mainly by burning
coal, oil, petrol and natural gas, which puts carbon dioxide – a
greenhouse gas – into the atmosphere. Global warming will result in
major harm to humanity if left unchecked. The solution is to stop
using fossil fuels for our energy supply and switch to solar and wind
power, and to adapt to some of the coming climate change.
Geoengineering by
blocking sunlight should not be implemented now, as its risks and
benefits are too uncertain, but we need more research on the various
proposed scenarios. Taking carbon dioxide out of the air is a good
thing, but currently extremely expensive, and we need research on
that, too.
The 2014
US Quadrennial Defense Review makes
clear that climate change poses a major threat to the US and the rest
of the world. It says: “The pressures caused by climate change will
influence resource competition while placing additional burdens on
economies, societies, and governance institutions around the world.
These effects are threat multipliers that will aggravate stressors
abroad such as poverty, environmental degradation, political
instability, and social tensions – conditions that can enable
terrorist activity and other forms of violence.”
Certainly
it is the job of the US military and the CIA to help protect our
country from such threats, and it is not surprising that the CIA is
interested to learn about geoengineering. In fact, the CIA opened
a Center
on Climate Change and National Security in 2009.
When it was forced
by Congress to close it in 2012,
it said they would continue working on these issues anyway.
Whether
you see the role of the CIA in climate change as nefarious or
protective depends on how you weigh evidence with your preconceived
notions. There is a long history of weather and climate control being
proposed for military purposes, as described brilliantly in the 2010
book by James Fleming, Fixing
the Sky,
but there is no evidence the CIA is doing anything wrong on this
issue. I know of no way to control local or regional climate with
geoengineering without effects elsewhere, but while it is possible
that such techniques could be developed by research, geoengineering
for hostile purposes is prohibited by the United Nations Convention
on the Prohibition of Military or Any Other Hostile Use of
Environmental Modification Techniques.
I
don’t want to be working on geoengineering. But I don’t yet see
the political will in the world to address global warming. If the US
enhances its research efforts on geoengineering, we will learn about
both the potential risks and benefits of its implementation, so that
future policymakers will be able to make informed decisions, and not
hasty ones in a panic if confronted by environmental dangers.
My
recent work lists five potential benefits and 26 potential risks of
stratospheric geoengineering, and the number one benefit – if
stratospheric geoengineering is possible at all (an important
research question) – is that it could cool the planet, reversing
some of the dangers of global warming. But will we ever be able to
overcome the governance and ethical issues?
Thus
further research is urgently needed. In the meantime, we need to
vigorously move to a carbon-free energy system.
