Presentation by Björn Sörgel (PIK) at the SHAPE final conference “New Sustainable Development path-ways reflecting different societal perspectives”
The SHAPE final conference “"New Sustainable Development pathways reflecting different societal perspectives" took place on February 16th, 2023 online shape-project.org/products/final-conference)
Achieving the Paris Agreement and the Sustainable Development Goals (SDGs) set out in the Agenda 2030 requires holistic Sustainable Development Pathways (SDPs) that maximise synergies and avoid, minimise or compensate for trade-offs. The orientation towards this much broader target space challenges the IAM community to broaden their previous scope considerably. The SHAPE Project has addressed this gap by aiming at creating and modelling a set of Sustainable Development Pathways (SDPs) with multiple integrated assessment models. The project’s multi-method approach involved a co-creative narrative design process, as well as analyses of governance, equity and material flows.

![The Hysteresis of the Antarctic Ice Sheet
The warmer it gets, the faster Antarctica loses ice – and much of it will then be gone forever. Consequences for the world’s coastal cities and cultural heritage sites would be detrimental, from London to Mumbai, and from New York to Shanghai. That’s what a team of researchers from the Potsdam Institute for Climate Impact Research, Potsdam University and New York’s Columbia University has found out in their new study, published in Nature (cover story), on how much warming the Antarctic Ice Sheet can survive. In around one million hours of computation time, their unprecedentedly detailed simulations delineate where exactly and at which warming levels the ice would become unstable and eventually melt and drain into the ocean. They find a delicate concert of accelerating and moderating effects, but the main conclusion is that unmitigated climate change would have dire long-term consequences: If the global mean temperature level is sustained long enough at 4 degrees above pre-industrial levels, Antarctic melting alone could eventually raise global sea levels by more than six meters.
The animation shows the modelled long-term evolution of the Antarctic Ice Sheet under steadily increasing temperatures.
The upper panel shows the ice sheets surface elevation change (in meters; grey shading), the ocean-induced melting at the base of the floating ice shelves (in meters per year; purple–orange shading), as well as the topography of the bed underneath the ice sheet and the surrounding ocean (in meters above the present-day sea level; blue–brown shading).
The lower panel shows the total sea-level relevant ice volume change (in meters of sea-level equivalent ; blue curve) and total ice mass flux (in gigatons per year; purple curve).

![Flipping the switch: making use of carbon price dollars for health and education
While health systems, clean water and education are a plain given in many parts of the world, millions of people still do not have sufficient access to these basic public goods. In fact, carbon prices could make substantial financial resources available for succeeding with the global Sustainable Development Goals (SDGs) set by the United Nations, a team of scientists now finds. At the same time, carbon pricing could be a central contribution to meet global climate targets and limit global warming to well below 2°C until the end of the century.
