The amount of marine science papers on climate change
has doubled every five years since the release of the first UN report on
climate change in 1990.
In the last 15 years, marine science has become
increasingly dominated by the topic of climate change, shows new research.
And it is not just the physical sciences of
oceanography and climatology that are focussed on how climate change affects
the oceans. Marine biologists and ecologists have also shifted their focus to
climate.
“There’s been a huge growth in the proportion of
climate change research within the field of marine science,” says lead-author
Martin Pedersen, postdoc at the National Institute of Aquatic Resources,
Technical University of Denmark (DTU).
According to Pedersen, this growing interest in
climate change among marine scientists coincides with the publication of the
first report from the UN’s Intergovernmental Panel on Climate Change (IPCC) in
1990.
“Many people know of the IPCC reports, not only in
the scientific community but it’s also in the general news. So even though we
can’t prove that it’s the main driver [of shifting focus in marine science],
I’m pretty sure that it’s had a huge influence,” says Pedersen.
Climate change a growing concern to marine science
Pedersen and colleagues sorted through almost 2,800
marine science articles published in scientific journals since 1990. Of these,
1,362 dealt with the topic of climate change.
They grouped all of these articles into different
disciplines, including the physical sciences with a focus on the ocean or
atmosphere, the biological sciences, and the social sciences, which looked at
economic aspects such as the livelihood of fishermen affected by climate
change.
If a paper shared more than one discipline it would
be labelled as inter-disciplinary.
They saw that since the first IPCC report in 1990,
the number of scientific studies in marine science as a whole has doubled every
ten years.
And within marine science itself, the number of
scientific studies focussed on climate change has increased twice as
fast--doubling every five years. This is a huge shift in the focus of marine
scientists to the issue of climate change, says Pedersen.
Biologists more aware of climate change
But it is not just the total number of climate
change studies that have shot up. Where once oceanographers and climatologists
dominated climate change research, there is now an increasing focus on the
topic from marine biologists.
“These disciplines [physical sciences] have studied
climate change for a long time, well before the IPCC, so we wouldn’t expect
this branch of science to explode simply as a result of the IPCC,” says Pedersen.
“But it could have caused the biological sciences
to have changed focus as they become more aware of climate change,” he says.
Not only the IPCC that has scientists’ attention
Not all marine scientists are convinced that the
IPCC is the main driver of this shifting focus to the topic of climate change.
Marine Biologist Christiane Lancelot, from the
Université Libre de Bruxelles recently chaired a session on the changing face
of marine sciences at the largest
Earth Science conference held annually in San Francisco, USA.
Asked whether the IPCC has changed the face of
marine sciences she writes, “This is true but not exactly true,” in an email to
ScienceNordic.
“At the same time [end of the 1980s] ICSU
[International Council for Science] launched the International Geosphere
Biosphere Program on Global Change research,” writes Lancelot.
According to her, this large review program has
also focussed scientists’ attention to the issues of climate change and
contributed to the changing face of research across different disciplines.
Social Scientists yet to come on board
But not all scientists have shifted their focus to
climate. Social scientists have published comparatively little on the topic of
climate change in the marine environment.
Pedersen attributes this in part to the large
investments in funding for international research teams and long running
projects in the natural and biological sciences that has amassed huge amounts
of data over the last 15 years.
“The big biological data collection programs for
example are well organised, big projects, and often international. And they’re
well funded, which you don't really have in the social sciences. Of course,
there’s loads of data, but perhaps they’re not as accessible to social scientists
as they are to biologists,” he says.
There are also relatively few interdisciplinary
studies, indicative of how scientists from different disciplines still do not
have many opportunities to interact and work together, says Pedersen.
