We present a high resolution seawater pH record across this interval, utilizing boron isotope data (δ11B) combined with petrographic analysis and a quantitative modeling approach. Through this integration we are able to produce an envelope that encompasses the most realistic range in pH, which then allows us to resolve three distinct chronological phases of carbon cycle perturbation, each with very different environmental consequences for the Late Permian-Early Triassic Earth system. In the latest Permian, increased ocean alkalinity, primed the Earth system with a low level of atmospheric CO2 and a high ocean buffering capacity. The first phase of extinction was coincident with a slow injection of carbon into the atmosphere and ocean pH remained stable. During the second extinction pulse, however, a rapid and large injection of carbon caused an abrupt acidification event that drove the preferential loss of heavily calcified marine biota.

  • Ocean Acidification and Climate Change: Synergies and Challenges
    n synthesis 5 Ocean acidification and climate change: synergies and challenges of addressing both under the UNFCCC ELLYCIA R. HARROULD-KOLIEB1, DOROTHE´E HERR2* 1 10 School of Land and Environment, University of Melbourne, Melbourne, VIC 3010, Australia 2 Global Marine and Polar Programme, International Union for Conservation of Nature (IUCN), Suite 300, 1630 Connecticut Avenue NW, Washington, DC 20001, USA 15 Ocean acidification and climate change are linked by their common driver: CO2. Climate change is the consequence of a range of GHG emissions, but ocean acidification on a global scale is caused solely by increased concentrations of atmospheric CO2. Reducing CO2 emissions is therefore the most effective way to mitigate ocean acidification. Acting to prevent further ocean acidification by reducing CO2 emissions will also provide simultaneous benefits by alleviating future climate change. Although it is possible that reducing CO2 emissions to a level low enough to address ocean acidification will simultaneously address climate change, the reverse is unfortunately not necessarily true. Despite the ocean’s integral role in the climate system and the 20 potentially wide-ranging impacts on marine life and humans, the problem of ocean acidification is largely absent from most policy discussions pertaining to CO2 emissions. The linkages between ocean acidification, climate change and the United Nations Framework Convention on Climate Change (UNFCCC) are identified and possible scenarios for developing common solutions to reduce and adapt to ocean acidification and climate change are offered. Areas where the UNFCCC is currently lacking capacity to effectively tackle rising ocean acidity are also highlighted. 25 Keywords: climate change; climate policy; ocean acidification; oceans; UNFCCC L’acidification des oce´ans et le changement climatique sont lie´s par leur cause commune : le CO2.

  • Ocean Acidification Summary for Policymakers – Third
    O A Summary for Policymakers Third Symposium on the Ocean in a High-CO2 World Scientific sponsors: The International Geosphere-Biosphere Programme (IGBP) was launched in 1987 to coordinate international research on global-scale and regional-scale interactions between Earth’s biological, chemical and physical processes and their interactions with human systems. IGBP’s international core projects Integrated Marine Biogeochemistry and Ecosystem Research (IMBER), Surface Ocean–Lower Atmosphere Study (SOLAS), Past Global Changes (PAGES) and Land–Ocean Interactions in the Coastal Zone (LOICZ) study ocean acidification. The Intergovernmental Oceanographic Commission (IOC-UNESCO) was established by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 1960 to provide Member States of the United Nations with an essential mechanism for global cooperation in the study of the ocean. The Scientific Committee on Oceanic Research (SCOR) was established by the International Council for Science (ICSU) in 1957 and is a co-sponsor of the international projects IMBER and SOLAS.

  • Effects of Climate Change on Ocean Acidification Relevant to the Pacific Islands
    PACIFIC MARINE CLIMATE CHANGE REPORT CARD Science Review 2018: pp 31-42 Effects of Climate Change on Ocean Acidification Relevant to the Pacific Islands Andrew Lenton, Richard J. Matear, and Mathieu Mongin, CSIRO Oceans and Atmosphere, Australia. EXECUTIVE SUMMARY Ocean acidification has the potential to significantly impact Pacific Island ecosystems and the ecosystem services they provide. There is compelling evidence that the ocean has become more acidic in response to rising atmospheric CO2 levels. As atmospheric CO2 levels continue to rise the ocean will increasingly become more acidic, and these changes are likely to persist for hundreds to thousands of years. The rate and magnitude of these changes will be directly proportional to the future carbon emission pathway followed. While a low carbon emissions pathway will clearly limit the impacts of ocean acidification, a high carbon emission pathway will lead to conditions that will threaten the long-term viability of important marine ecosystems, such as coral reefs. In the future, increased confidence in projected changes will come through a better understanding of how the large-scale changes are modulated by processes at the island scale. This will be achieved through a combination of sustained long-term measurements and higher-resolution modelling. There is also critical need to understand the impact of multiple environmental stressors, as future ocean acidification will be accompanied by ocean warming and other environmental consequences (e.g. invasive species). Finally, implementation of a viable emission pathway is urgently needed to underpin the development of sustainable adaption and resilience options, and to explore potential engineering and adaptation solutions that may be required to offset long-term ocean acidification changes.

  • Ocean Acidification and the UNFCCC
    Climate Change and Ocean Acidification Synergies and Opportunities within the UNFCCC Discussion Paper Ellycia Harrould-Kolieba and Dorothée Herrb Executive Summary Ocean acidification is arguably one of the most serious threats facing the oceans and humans this century. Ocean acidification is not a symptom of climate change; rather, it is a threat concurrent with climate change and caused by a common root problem: ongoing anthropogenic CO2 emissions. It is a serious global challenge of unprecedented scale and importance that requires immediate action. Preventing further acidification of the oceans will require stabilizing and reducing the level of CO2 in the atmosphere, which is most effectively done through reducing CO2 emissions. The United Nations Framework Convention on Climate Change (UNFCCC) is clearly an appropriate environmental policy regime to deal with the mitigation of ocean acidification, through CO2 reductions. It is also a suitable forum for devising and providing funding for responses to ocean acidification that can be incorporated into national adaptation plans. Many efforts are underway to raise awareness and inform policy and decision makers about ocean acidification and its potential impacts. So far, however, no concrete recommendations have been made on how ocean acidification could be integrated within the UNFCCC. This paper attempts to address this gap by offering an initial suite of possible ways to address ocean acidification alongside climate change mitigation and adaptation strategies.
