Franziska Piontek, Thomas Vogt, Peron Collins-Sowah, (PIK); Stéphane Zuber (CNRS); Simon Feindt (MCC) at the CHIPS final event “Current Crises and Future Climate Change: How to prevent rising inequality and societal conflict"
The CHIPS final event, titled "Current Crises and Future Climate Change: How to prevent rising inequality and societal conflict", took place on 27 February 2023 as an online event.
The event aimed at discussing the project's results in the context of the current challenges to inequality: The achievements in reducing inequality over the last decades are currently threatened by multiple crises: the energy and food crisis caused by the pandemic and the war in Ukraine, as well as the increasing impacts of climate change. This has the potential to cause or reinforce societal conflicts worldwide. Sustainable policy solutions have to include the different short- and long-term effects to protect especially the most vulnerable groups. Distributional consequences of climate change policies and impacts and how to best address them on different scales were subject of the CHIPS project. Results comprise advanced integrated assessment models, now including subnational inequalities, and bottom-up microsimulation and empirical studies of inequality complementing the global approach.

![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).
Abbreviations: EAIS, East Antarctic Ice Sheet; WAIS, West Antarctic Ice Sheet; IS, ice shelf; FRIS, Filchner–Ronne Ice Shelf.

![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.
