The 2015 agreement setting forth the UN Agenda 2030 for Sustainable Development Goals (SDGs) is an important achievement that poses complex and demanding challenges. To adequately address them, judgments must determine contextually and culturally appropriate balances between independently valuable, but often conflicting targets (Singh et al. 2018). Simultaneously, a global coherence across local and regional actions must be ensured, so that local efforts do not destructively interfere with each other, nor overstep limitations in the resources of the planet (Randers et al. 2018). The Global Sustainability Strategy Forum (GSSF) responds to the fact that, after some 40 years sustainability science has produced many insights, but has not really affected our collective behavior with respect to its impact on the environment. Generally, that is deemed to be the result of lack of communication between scientists and the outside world. But might it be that the present practice of science is in itself deficient in producing results that are useful to implement the changes called for? The Forum was established in 2018 with funding from the VW Foundation to identify and address sustainability challenges at the global to regional scales by bringing together, in week-long work-shops, renowned experts in sustainable development and thought leaders in business, government, and civil society from around the world. Under the patronage of Prof. Dr Rita Süssmuth, former President of the German Bundestag, the first Forum was coordinated by Solène Droy with assistance from Paul Skaloud. Moderated by Ilan Chabay (IASS), Sander van der Leeuw (Arizona State University), Ortwin Renn (IASS), 14 panelists convened in Potsdam (Germany) 4-8 March 2019. Eight main lessons emerged from in-depth discussions and reflections towards the end of the forum. They capture some of the main approaches deemed as necessary for science and society to counter patterns and trends of unsustainability and are outlined in this paper. The results were ...

We summarize some of the past year's most important findings within climate change-related research. New research has improved our understanding about the remaining options to achieve the Paris Agreement goals, through overcoming political barriers to carbon pricing, taking into account non-CO2 factors, a well-designed implementation of demand-side and nature-based solutions, resilience building of ecosystems and the recognition that climate change mitigation costs can be justified by benefits to the health of humans and nature alone. We consider new insights about what to expect if we fail to include a new dimension of fire extremes and the prospect of cascading climate tipping elements. Technical summary. A synthesis is made of 10 topics within cli- mate research, where there have been significant advances since January 2020. The insights are based on input from an inter- national open call with broad disciplinary scope. Findings include: (1) the options to still keep global warming below 1.5 °C; (2) the impact of non-CO2 factors in global warming; (3) a new dimension of fire extremes forced by climate change; (4) the increasing pressure on interconnected climate tipping elements; (5) the dimensions of climate justice; (6) political chal- lenges impeding the effectiveness of carbon pricing; (7) demand- side solutions as vehicles of climate mitigation; (8) the potentials and caveats of nature-based solutions; (9) how building resili- ence of marine ecosystems is possible; and (10) that the costs of climate change mitigation policies can be more than justified by the benefits to the health of humans and nature. Social media summary. How do we limit global warming to 1.5 °C and why is it crucial? See highlights of latest climate science.
