CORAL REEFS: Tipping Elements, Irreversibility, and Abrupt Change

20 October 2022 15:30-17:00 CEST

Coral reefs & potential tipping points

Join AIMES, the Earth Commission, Future Earth, and WCRP for a webinar focused on the potential tipping points of coral reefs, as part of a series that aims to advance the knowledge about tipping elements, irreversibility, and abrupt changes in the Earth system. The event includes two presentations on the potential tipping of coral reefs and associated impacts on ocean ecosystems (MIRO board).

Presentations by

How close are we to coral reefs tipping? - David Obura (Founding Director of CORDIO East Africa)
Can we avoid or delay the tipping point for coral reefs?- Joanie Kleypas (National Center for Atmospheric Research)
Q&A/ Discussion

Moderated by Albert Norström (Stockholm Resilience Centre).

The recording of this event is provided below.

Speakers

David Obura
Founding Director of CORDIO East Africa

David Obura is a Founding Director of CORDIO East Africa and a commissioner for the Earth Commission. CORDIO East Africa is a knowledge organization supporting sustainability of coral reef and marine systems in the Western Indian Ocean. CORDIO takes research to management and policy, builds capacity, and works with stakeholders, managers and policy makers. David’s primary research is on coral reef resilience, in particular to climate change, and the biogeography of the Indian Ocean.

Joanie Kleypas
National Center for Atmospheric Research

Joanie Kleypas is a marine ecologist/geologist that focuses on how coral reefs and other marine ecosystems are affected by changes in the Earth's atmosphere and climate. Global warming, for example, is causing tropical ocean temperatures to increase faster than corals can adapt, resulting in high rates of coral bleaching. This is one of the major causes of the present, rapid degradation of coral reef ecosystems. Ocean acidification is another major threat to coral reefs, because as the oceans absorb much of the CO2 released to the atmosphere by fossil fuel burning and deforestation, seawater pH declines and reduces the ability of corals and many other organisms to build their skeletons and shells.

All you need to know

This event is part of a series of online discussions aims to advance the knowledge about tipping elements, irreversibility, and abrupt changes in the Earth system. It supports efforts to increase consistency in treatment of tipping elements in the scientific community, develop a research agenda, and design joint experiments and ideas for a Tipping Element Model Intercomparison Project (TipMip).

This discussion series is a joint activity of the Analysis, Integration, and Modeling of the Earth System (AIMES) global research project of Future Earth, the Earth Commission Working Group 1 Earth and Human Systems Intercomparison Modelling Project (EHSMIP) under the Global Commons Alliance and the Safe Landing Climates Lighthouse Activity of World Climate Research Program (WCRP).

Organized by

Analysis, Integration, and Modeling of the Earth System (AIMES)

The Analysis, Integration, and Modeling of the Earth System (AIMES) project is an international network of Earth system scientists and scholars that seek to develop innovative, interdisciplinary ways to understand the complexity of the natural world and its interactions with human activities. AIMES is a global research project of Future Earth.

Earth Commission

The Earth Commission is a major scientific assessment, hosted by Future Earth, to define a safe and just corridor for people and planet. The Commission will inform the creation of science-based targets, the “1.5-degree equivalents”, to help maintain and protect critical global commons – our shared climate, land, biodiversity, freshwater, atmosphere and oceans. The Earth Commission is an international team of leading natural and social scientists and five working groups of additional experts. It forms the scientific cornerstone of the Global Commons Alliance.

Future Earth

Future Earth is a global network of scientists, researchers, and innovators collaborating for a more sustainable planet. Future Earth initiates and supports international collaboration between researchers and stakeholders to identify and generate the integrated knowledge needed for successful transformations towards societies that provide good and fair lives for all within a stable and resilient Earth system. Future Earth is the host of the Earth Commission.

WCRP Safe Landing Climates Lighthouse Activity.

The Safe Landing Climates Lighthouse Activity is an exploration of the routes to “safe landing” spaces for human and natural systems. It will explore future pathways that avoid dangerous climate change while at the same time contributing to the United Nations Sustainable Development Goals (SDGs), including those of climate action, zero hunger, clean water and sanitation, good health and well-being, affordable and clean energy, and healthy ecosystems above and below water. The relevant time scale is multi-decadal to millennial.

World Climate Research Programme

The World Climate Research Programme (WCRP) leads the way in addressing frontier scientific questions related to the coupled climate system — questions that are too large and too complex to be tackled by a single nation, agency or scientific discipline. Through international science coordination and partnerships, WCRP contributes to advancing our understanding of the multi-scale dynamic interactions between natural and social systems that affect climate.
