TiPACCs – Tipping Points in Antarctic Climate Components
TiPACCs is a European Horizon 2020 research project investigating the possibility of sudden and large changes in Antarctic Climate Components. Recently, researchers found relatively warm waters below Antarctic ice shelves, indicating that the Antarctic continental shelf seas can tip from a ‘cold’ to a ‘warm’ state. Concurrently, recent research indicates that ice sheets, especially the parts of the ice sheet that rest on a bed below sea level, are prone to an unstable and irreversible retreat. The change in these two components (cold-to-warm ocean, and stability regime of the Antarctic Ice Sheet) are linked through to the impact that ice shelves can have on the upstream ice sheet and on the ocean below. If irreversible changes occur in the Antarctic components, and so-called tipping points are crossed, the ice sheet will likely quickly retreat, causing a dramatic increase in global mean sea level.

Most human activity in the Arctic takes place along permafrost coasts and these coasts have become one of the most dynamic ecosystems on Earth. Permafrost thaw is exposing these coasts to rapid change, change that threatens the rich biodiversity, puts pressure on communities and contributes to the vulnerability of the global climate system. NUNATARYUK will determine the impacts of thawing coastal and subsea permafrost on the global climate, and will develop targeted and co-designed adaptation and mitigation strategies for the Arctic coastal population.NUNATARYUK brings together world-leading specialists in natural science and socio-economics to:
- develop quantitative understanding of the fluxes and fates of organic matter released from thawing coastal and subsea permafrost;
- assess what risks are posed by thawing coastal permafrost, to infrastructure, indigenous and local communities and people’s health, and from pollution;
- use this understanding to estimate the long-term impacts of permafrost thaw on global climate and the economy.
NUNATARYUK will be guided by a Stakeholders’ Forum of representatives from Arctic coastal communities and indigenous societies, creating a legacy of collaborative community involvement and a mechanism for developing and applying innovative evidence-based interventions to enable the sustainable development of the Arctic.
