A growing number of studies have demonstrated adverse impacts
on marine organisms as a result of ocean acidification, including the following: ref
«Several experiments have demonstrated that the effects of various environmental
factors on marine organisms either add up or attenuate each other.
Prof. Ulf Riebesell, marine biologist at GEOMAR Helmholtz Centre for Ocean Research Kiel and coordinator of the German research network on ocean acidification BIOACID, has been among the first scientists who investigated the effects of carbon
dioxide on marine organisms.
Biography: Sue - Ann's research focuses on key ecological effects of global change, particularly ocean acidification,
on marine organisms including invertebrates and fishes.
Topic 1.7: Medicine and the Oceans: Development of Marine - Based Pharmaceuticals and the Impacts of Pharmaceuticals on Marine Organisms
Our findings, combined with the emerging evidence on the impacts of aragonite
undersaturation on marine organisms imply that not only radiative forcing or temperature, but also atmospheric CO2 concentration should be included as a target in climate policy analyses and in the development of mitigation scenarios with integrated assessment models.
This is what the IPCC says in AR4: The consequences of changes in
pH on marine organisms are poorly known (see Section 7.3.4 and Box 7.3).
For even if the models are proven to be wrong with respect to their predictions of atmospheric warming, extreme weather, glacial melt, sea level rise, or any other attendant catastrophe, those who seek to regulate and reduce CO2 emissions have a fall - back position, claiming that no matter what happens to the climate, the nations of the Earth must reduce their greenhouse gas emissions because of projected direct negative impacts
on marine organisms via ocean acidification.
Among the greatest concerns is that compounds in oil called polycyclic aromatic hydrocarbons (PAHs) could have long - term sublethal
effects on marine organisms that were at the peak of their spawning season when the spill began.
«Ocean acidification is already having impacts
on marine organisms and the scale and magnitude of the impact on life in the ocean and the services they support will increase.
Theme 2 quantifies impacts of ocean acidification
on marine organisms and ecosystems.
A growing number of studies have demonstrated adverse impacts
on marine organisms, including decreases in rates of coral calcification, reduced ability of algae and zooplankton to maintain protective shells, and reduced survival of larval marine shellfish and fish [13], [14], [15].
Meta - analysis reveals negative yet variable effects of ocean acidification on marine organisms
