Published 20 December 2022 Presentations , Resources ClosedTags: resource, video, video/audio
Prof Ove Hoegh-Guldberg was among the first to sound the alarm of the threat posed by ocean warming and acidification to marine ecosystems, following pioneering research into coral bleaching and mortality.
In his 29 November keynote at the Frontiers Forum, Ove gave an update on coral reef health globally and an outlook for the future. The session was attended by over 1,500 representatives from science, policy, and business across the world.
Ove’s talk was followed by a discussion with renowned coral scientists on how to protect and restore reefs so they flourish for centuries to come:
- Prof Maoz Fine | Professor, Hebrew University of Jerusalem, Israel
- Lisa Carne | Director/Founder, Fragments of Hope, Belize
- Dr Nancy Knowlton | Sant Chair for Marine Science Emerita, Smithsonian National Museum of Natural History, USA
Ove led the team that revealed the molecular mechanisms of coral bleaching and developed the first projections of mass coral mortality. He heads global research, discussions, and action on the science and solutions to rapid climate change – including as Coordinating Lead Author for the ‘Oceans’ chapter for the Fifth Assessment report of the Intergovernmental Panel on Climate Change (IPCC) and Coordinating Lead Author on the ‘Impacts’ chapter of the IPCC Special Report on 1.5°C. He also conceived and led the innovative XL-Catlin Seaview Survey, which visually recorded the health of over 1,000 km of coral reefs across 25 countries. Ove is Professor of Marine Studies at the University of Queensland, Australia.

Prof Tim Ravasi and Dr Davide Spatafora present their research on how the molecular basis and behavioural adjustments reveal potential local adaptation to acidifying oceans, a lesson from natural analogues, the second webinar from the International CO2 Natural Analogues (ICONA) Network. The first response by animals to a changing environment is predominantly through modification of their behaviour. In this context, investigating behavioural responses of fish living under low-pH/high-CO2 conditions (e.g. off volcanic seep sites) may contribute to a better understanding of how marine species might adjust or adapt to environmental conditions under projected ocean change scenarios. We carried out field-based observations and translocation experiments in the Vulcano island natural CO2 seep (southern Italy) to assess whether there is evidence for local behavioural adaptation and/or acclimatization of fish after long and short-term exposure to ocean acidification conditions predicted to occur by the end of this century. The responses of two temperate fish species, characterized by a limited home range, have been investigated and compared between fish from low-pH/high pCO2 sites and fish from control sites. Furthermore, understanding the molecular underpinnings responsible for acclimatization to acidified waters, by means of an integrated study of the brain transcriptional program of wild fish species, can elucidate on the variation in responses. We collected 130 individuals of six different reef fish species from a natural volcanic CO2 seep and nearby control reefs in Papua New Guinea. Differences in brain gene expression in fish from CO2 seeps compared to fish from control sites as well as differences among species identified the molecular pathways controlling the cellular responses to elevated CO2. These studies provide a broader understanding as to the behavioural and molecular alterations crucial for coping with naturally elevated CO2 conditions.

Published 21 September 2022 Science ClosedTags: education, resource, tool/toolkit
Sustainability has a molecular basis that suggests a central role for chemistry in addressing today’s challenges to Earth and societal systems, and this role requires educators to see chemical reactions and processes as integral parts of dynamic and interconnected systems. Despite this prospect, few accessible resources are available for students and educators to facilitate systems thinking in chemistry for sustainability. We have developed an interactive digital learning tool (https://planetaryboundaries.kcvs.ca) based on the Planetary Boundaries framework, which uses interactive visualizations to help users better understand Earth system sustainability challenges and helps chemists and educators connect substances, reactions, and chemistry concepts to sustainability science. The tool highlights the fundamental role that chemistry plays in regulating the individual biophysical Earth system processes and in determining their control variables. It incorporates key features of a systems thinking framework by illustrating the dynamic interconnections among the processes and their control variables and demonstrates change of the Earth system over time. Finally, the interactive tool provides educators with accessible entry points to support the integration of chemistry curriculum content with sustainability considerations.

The International Alliance to Combat Ocean Acidification (OA Alliance) brings together governments and organizations from across the globe dedicated to taking urgent action to protect coastal communities and livelihoods from the threat of ocean acidification and other climate- ocean impacts.
Facilitated through the OA Alliance, national, subnational, regional and tribal governments are proactively responding to the impacts of ocean acidification as they create OA Action Plans to effectively promote solutions and advancing knowledge into action.
The OA Alliance has created this Action Plan Toolkit as a guide. The OA Action Toolkit contains both regulatory and non-regulatory actions that members might consider when crafting their own OA Action. Not all OA Action plans will have the same framework or structure, as there is no “one- size fits all” approach.
Some members may choose to write a stand-alone plan, while others may decide to integrate ocean acidification mitigation, adaptation and resiliency actions across existing Climate Action Plans, Ocean Action Plans, Biodiversity or Resilience Goals and Targets, Nationally Determined Contributions pursuant to the Paris Climate Agreement, or decide to integrate and strengthen actions across other applicable management tools.
