Hutchison medal awarded for Ocean fertilization for geoengineering
publication

The Hutchison medal was recently awarded to a multinational group of
academics*, lead by Phillip Williamson, for their paper 'Ocean
fertilization for geoengineering: a review of effectiveness, environmental
impacts and emerging governance'. The medal is awarded annually by the
Institution of Chemical Engineers (IChemE) for practical and wide-ranging,
philosophical or thought-provoking published papers that will stimulate
further debate within the chemical engineering community.

The paper provides a review the state of knowledge on large-scale ocean
fertilization by adding iron or other nutrients, either from external
sources or via enhanced ocean mixing. It arose directly from a scientific
summary for policy makers by the same authors, published by the
Intergovernmental Oceanographic Commission (IOC-UNESCO) with the assistance
of the Surface Ocean-Lower Atmosphere Study (SOLAS).

Few subjects are as controversial as geoengineering –the deliberate
intervention in the planetary environment of a nature and scale intended to
counteract anthropogenic emissions. The potential side effects of
geoengineering are presently not well understood and will likely include
unintended ecological consequences, which in turn can pose important
political, social, and ethical challenges. In truth, dangerous climate
change is best avoided by drastically and rapidly reducing greenhouse gas
emissions. Nevertheless, geoengineering options are receiving attention on
the basis that additional approaches may also be necessary.

The paper highlights that, while ocean fertilization can increase the
uptake of CO2 across the ocean surface, long-term sequestration is
difficult to assess, and unintended impacts of ocean fertilization may be
far removed in space in time. It further concludes that 'research results
to date, taken together, do not support the idea that ocean fertilization
would provide a particularly effective approach to counteract the
increasing atmospheric levels of CO2, even within a wider portfolio of
measures. The avoidance of undesirable climate change therefore requires
more direct and urgent policy action.'

The United Nations General Assembly has encouraged States to support
further study and to enhance understanding of ocean fertilization. Member
States have stressed repeatedly that the precautionary principle is
fundamental to the regulation of ocean fertilization, notably during the
25th IOC-UNESCO Assembly in 2009, the 2012 Conference of the Parties to the
Convention on Biodiversity and in the outcome document of the United
Nations Conference on Sustainable Development (Rio+20) adopted in 2012,
which states ‘We stress our concern about the potential environmental
impacts of ocean fertilization. In this regard, we recall the decisions
related to ocean fertilization adopted by the relevant intergovernmental
bodies, and resolve to continue addressing ocean fertilization with utmost
caution, consistent with the precautionary approach’ (The Future We Want,
§167).
