Study urges global-change researchers to embrace variability

Scientists typically make every effort to keep all factors but one constant when doing an experiment. Global-change scientists might move a coral from a reef to an aquarium whose water is held 1°C higher to test the effects of the ocean warming predicted for the end of the century. Or they might decrease the water’s pH by 0.4 units to study the effects of ocean acidification.

But a new review article presents evidence that argues for a more nuanced approach to the design of these experiments—one that acknowledges and purposefully incorporates the variability inherent in nature.

International Alliance to Combat Ocean Acidification announces new members, including Fiji, and new plans for action at climate talks in Bonn

BONN, Germany (13. November, 2017) – As part of the UN Climate Change Conference, COP23, the International Alliance to Combat Ocean Acidification (OA Alliance) today announced new members, including the Republic of Fiji, and new commitments from world leaders to take action to protect oceans from the impacts of climate change. High-level government officials from around the world gathered to engage in meaningful conversations about ocean acidification (OA) and steps OA Alliance members can take to mitigate impacts through the United Nations Framework Convention on Climate Change.

The OA Alliance, founded by the West Coast states of California, Washington, Oregon and the Canadian Province of British Columbia, welcomed five new members to a rapidly growing worldwide coalition of governments and supporting affiliates committed to creating regional ocean acidification action plans and sharing climate action best practices with each other. The newest official members of the OA Alliance are Fiji, Sweden, the Secretariat of the Pacific Regional Environment Programme (SPREP) and the scientific and technical organization Pacific Community (SPC). Tokelau also announced their intention to join the OA Alliance at today’s event.

Study of Bermuda corals finds temperature is most influential factor on coral growth

Scientists have long been concerned that decreasing ocean pH (increasing acidity) caused by increasing carbon dioxide emissions in the atmosphere could negatively impact coral reefs. Many laboratory experiments have demonstrated that increased ocean acidity slows down coral calcification, the process by which corals grow and build their hard structure. But far fewer studies have tested how increasing ocean acidity affects coral growth in the natural environment, where a multitude of additional factors such as light, temperature, and nutrients are also important.

A new paper based on research led by scientists at Scripps Institution of Oceanography at the University of California San Diego that was published this week in Science Advances found a surprising answer to this question. Scripps chemical oceanographer Andreas Andersson, his graduate student Travis Courtney, and an international team of collaborators from the Bermuda Institute for Ocean Sciences and Christian-Albrecht University in Germany, among others, were involved in the study funded by the National Science Foundation.

Tomorrow the Environment Minister Thérèse Coffey will head to the UN Climate Change Conference in Germany to discuss our world-class marine science and leading research into ocean acidification.

Saturday is ‘Oceans Action Day’ and the Minister will join leaders from around the world to address progress made on tackling climate change and its impacts on the marine environment.

Pacific has a stake in ocean activities

As large ocean states, we in the Pacific have a vital stake in what happens to the ocean, Professor Rajesh Chandra, Vice-Chancellor and President of USP said.

He made the comment during the Ocean Acidification Measuring and Monitoring Dinner on 2 November, 2017 at the Grand Pacific Hotel in Suva, Fiji.

USP, through the Pacific Centre for Environment and Sustainable Development (PaCE-SD), is hosting three Ocean Acidification workshops facilitated by Washington, DC-based NGO, The Ocean Foundation, for local, regional and international participants.

Developing regional capacity for ocean acidification observations in the Western Indian Ocean in support of the Sustainable Development Goal 14

Participants in the first WIOMSA Ocean Acidification Workshop – 24-25 October 2017, Dar es Salaam, Tanzania.

The ocean absorbs up to 30% of the annual emissions of anthropogenic CO2 to the atmosphere, helping to alleviate the impacts of climate change on our planet. However, this comes at a steep ecological cost, resulting in changing acidity levels in the ocean. On 24-25 October 2017, ocean acidification research and monitoring in the Western Indian Ocean region was promoted at a workshop in Dar Es Salaam, Tanzania.
