What's worse than geoengineering the climate?

Nick Breeze
23rd December 2014

Film maker Nick Breeze has conducted a series of interviews with experts on
'geo-engineering' to forestall runaway global warming. Here he presents the
distilled wisdom from his meetings - and concludes that we should at least
be experimenting with the techniques, and studying their impacts.

We need to research all technologies that have any likelihood of being
used. Knee-jerk use of technologies that haven't been researched scares me
a lot.

Within the recent Intergovernmental Panel on Climate Change (IPCC) AR5
report are a number of 'scenarios' of carbon dioxide emissions and global
temperatures.

The current trajectory that humanity is on is one that is predicted to take
us to a global temperature rise of 4C by 2100. When I interviewed IPCC
author Dr Saleemul Huq earlier this year he stated:"Four degrees ... is way
beyond ... anything we are likely to be able to cope with. The stated
desire for all countries is to stay below two degrees, so we are going in
the wrong direction and we need to change course very quickly."

But changing course is not something that we have been able to do and
according to Astronomer Royal, Professor Martin Rees, speaking to me in
2013, that's not about to change:

"I honestly would bet, sad though it is, that the annual CO2 emissions are
going to rise year by year for at least the next 20 years and that will
build up accumulative level close to 500 parts per million by then."

Or as Dr Matt Watson, a volcanologist at the University of Bristol's School
of Environmental Sciences, stated in his presentation at the Royal Society
recently:

"The very very alarming thing for us is that we are on RCP 8.5... we are
slap bang on this trajectory and this puts us on a very very different
place in our children's or grandchildren's lifetimes!"

BY 'RCP 8.5' he refers to the 'business as usual' scenario, or
'Representative Concentration Pathway'. Two other RCP's, 2.6' and 4.5'
respectively, are supposedly not quite as bad for humanity and that could
keep us within the 2 degrees limit by the end of the century.

Geoengineering for CO2 drawdown is built into the models

However, what these more attractive (but in reality still critically risky
for forest survival, agriculture and oceans etc) RCP's both assume, is that
we are geoengineering the climate by drawing down billions of tonnes of
carbon dioxide in order to lessen the greenhouse effect.This process, known
as carbon dioxide removal' (CDR), may sound like the perfect antidote to
the global warming crisis, but in practical terms, it is little more than
mirage. Dr Piers Fletcher from the Integrated Assessment of Geoengineering
Proposals' (IAGP) made this comment during his Royal Society presentation:

"I'm not going to talk much about the carbon capture technologies today ...
you've already heard they are in the IPCC report. We do not have enough
technological information about these technologies when they're operating
at the very large scales that is proposed."They have to take out 20 or 30
gigatonnes of CO2 out of the atmosphere annually and we don't have the
technological assessment to be really able to investigate them."

None of these carbon capture or 'carbon dioxide removal' (CDR) technologies
actually exist on a scale that could extract 20 or 30 gigatonnes of carbon
out of the atmosphere.

As Dr Hugh Hunt, senior lecturer in the Engineering Department at Cambridge
University and a co-investigator for SPICE,  stressed in an earlier
interview, "We don't handle 30 billion tonnes of anything."Therefore, the
barely survivable RCP's are actually not currently viable at all!'

This problem of surviving the century is what is prompting considerable
research into what can be done. The event at the Royal Society in November
focussed on another form of geoengineering called Solar Radiation
Management' (SRM).SRM is often regarded as the most terrifying form of
geoengineering because the proposals offer a kind of intervention that
resembles scary science-fiction.

For example, the SPICE project, represented at the Royal Society, are
proposing we extend 22km pipes into the stratosphere, suspended by balloons
the size of a football stadium, and pump millions of tonnes of particles up
there constantly to reflect the suns light back into space, in order to
cool the planet.

The scepticism and criticism surrounding this project is understandable.
What is often not reported is the degree to which the scientists running
the project are worried about such proposals.

Matt Watson, Principal Investigator in the Stratospheric Particle Injection
for Climate Engineering (SPICE) project, said in his presentation
that "this stuff scares me!" - going on to point out that

"I found it very difficult to disentangle my personal feelings about
geoengineering, which aren't particularly positive, to professional
framings where I have to be absolutely objective about the results I am
generating."I think it is important to go back to the observations we make
about climate change and say there are some very strong drivers for knowing
about this stuff ... there is a point at which it would be morally wrong
not to intervene somehow ... and we look like we are going there!"

This sense of the responsibility in the research of solar radiation
management is echoed by Dr Hugh Hunt who says:"My concern is that if it can
be cheap [to deploy geoengineering techniques] then politicians are going
to use it and if we are going to use that technology that has not been
researched properly, that is a dangerous thing to do. We need to research
all technologies that have any likelihood of being used. Knee-jerk use of
technologies that haven't been researched scares me a lot."

Currently there is very little funding available for researching climate
engineering. Many people have previously objected to funding these schemes
due to their long-term implications for deployment.

But this claim runs counter to the overarching conclusion that the climate
is getting severely worse and engineering solutions are comparatively cheap
to other areas of research. If we do not research them thoroughly then the
temptation by policymakers to attempt untested deployment to stave off
severe impacts may prove too much and leave us with even more disastrous
consequences.

As Dr. Hugh Hunt said in an interview in 2013, "if your house catches fire,
is that really the time to start designing the fire engine?"

Dr. Matt Watson also highlighted that huge companies like Apple spend
billions in research and development for their products and yet, in this
field of near emergency technology, we are spending a minuscule fraction of
that amount.

Yet the seriousness of the issue is reflected in the broad number of
organisations that are involved in the discussion taking place at the Royal
Society. These include: Natural Environment Research Council (NERC), Met
Office, Tyndall Centre, more than 10 British Universities among others.In
the final debate, the discussion got lively when Dr. Alison Wall from NERC
stated: "the Research Council has an open door all the time for projects to
come in and we have seen very very few in geoengineering."

This was immediately contradicted by Dr Alan Gadian of the Institute of
Atmospheric Sciences at Leeds University, who countered that NERC has
refused funding to Edinburgh University's Professor Stephen Salter for
Cloud Brightening SRM techniques at least three times, and they are now
having to seek overseas funding.

The main question being asked is how could climate engineering schemes be
governed when the effects could have global implications. Regarding global
climate engineering, Dr Jennifer Francis of Rutgers University made the
point:"Certainly we can cool it but it is not going to be uniform around
the world and its going to have a lot of knock on consequences. There will
be changes in precipitation patterns, and how do you say to a country
that's experiencing a big drought for example, whether it was the
geoengineering that did it, or whether it was going to happen naturally?"If
they are in dire straits they're going to blame the people who decided to
do the geoengineering. It opens up a whole can of worms in terms of
attribution and when we have extreme events, you can probably be find a
scientists to say 'Yes it was the geoengineering that did it.' and so a
whole set of lawsuits."

Martin Rees suggests that apart from the complexity of attribution, it is
the political system that is not focusing enough on this issue:

"The trouble is, of course, that it is very hard in politics to get these
long-term issues to rise high on the agenda because most politicians are
focused on the short-term agenda between now and the next general
election."We are also focussed on what happens locally as opposed to what
happens globally, so it is a big ask politicians to prioritise issues that
will affect people in remote parts of the world 50 or 100 years ahead but
that is what you have to do if you want to tackle the issues of climate
change which is caused by an unprecedented change in the Earth's atmosphere
due to the burning of fossil fuels."

But what is happening globally is affecting us all, even at 0.8 C
temperature increase since the beginning of the industrial revolution.With
dying oceans and rain forests, droughts affecting agriculture, extreme
weather impacts in both the developed and developing world, the
conversation about research into a controlled intervention into our climate
is one that must be had.

Dr Clive Hamilton, author of Earthmasters', a wide-ranging critique of
geoengineering, says "We've screwed up so badly. Not just with the burning
of fossil fuels but in all sorts of areas ..."To argue that the problem is
that we have not had enough technical intervention seems to me to be
wilfully ignoring the kind of reckless use that humans have made of our
technology."

One counter to this argument is that the industrial burning of fossil fuels
is essentially 19th century technology and our addiction to it is due
largely to the vested interested of those who benefit from the profits and
subsidy.

If we were to bring in the technology of the 21st century, there is a good
chance we could engineer ourselves out of the mess we have gotten ourselves
into.

Current predictions for climate change impacts are now too serious to be
ignored. Dr Saleemul Huq states:

"What we are seeing now since the last 2 decades of the IPCC reporting on
the science of climate change is ... [that] the actual temperature rise and
associated impacts that we see including sea ice and glacier ice melt are
way above the upper range of the predictions ..."We are hitting the upper
end of that range consistently ... it is quite possible that the ranges
that we gave are underestimates and the reality is much worse than we
imagined."

Solar radiation management is not a cure for the climate changes that are a
result of burning coal, oil and gas, nor for ocean acidification. It is
utterly useless without immediate decline in the use of fossil fuels to
power our civilisation.

However, it could provide a bridge whilst we research and implement a safe
carbon dioxide removal programme to undo some of the greenhouse effects.
This would require enormous international agreements and governance
structures to defend the most vulnerable.

When I spoke to Professor Peter Wadhams from the University of Cambridge
regarding how we can possibly stay within a safe range of atmospheric
concentrations of CO2, he said,"I would say it can only be done by some
complete breakthrough in CO2 removal technology. Which really does need a
global Manhattan-style project." This idea of a Manhattan Project' to draw
down carbon dioxide has been mooted for sometime, but as yet there are
still no plans on the table and certainly no significant funding body to
assist in implementing the research required to literally save humanity
from a catastrophic fate.

In this context we need to double down our efforts and include research
into solar radiation management on an equal scale as our worst case
scenario insurance policy.

And it goes without saying, all this needs to be achieved at the same time
as with immediate reduction in greenhouse gas emissions from all areas,
especially including energy and agriculture.Perhaps one thoughtful
conclusion to end is a quote from former Archbishop of Canterbury, Dr Rowan
Williams, who summarised:

"I am certainly not an advocate of climate engineering but I would like to
know what it is that I am saying no to, if I do want to say no to it, and I
want to know how we balance short term needs to save lives and protect the
vulnerable with the long-term anxieties we naturally have about governance
and other effects that go with exploring more aggressive approaches to
controlling our environment."
