Abstract Non-technical summary We identify a set of essential recent advances in climate change research with high policy relevance, across natural and social sciences: (1) looming inevitability implications overshooting the 1.5°C warming limit, (2) urgent need for rapid managed fossil fuel phase-out, (3) challenges scaling carbon dioxide removal, (4) uncertainties regarding future contribution sinks, (5) intertwinedness crises biodiversity loss change, (6) compound events, (7) mountain glacier loss, (8) human immobility face risks, (9) adaptation justice, (10) just transitions food systems. Technical The Intergovernmental Panel on Climate Change Assessment Reports provides scientific foundation international negotiations constitutes an unmatched resource researchers. However, assessment cycles take multiple years. As to cross- interdisciplinary understanding diverse communities, we have streamlined annual process synthesize significant advances. collected input from experts various fields using online questionnaire prioritized 10 key insights relevance. This year, focus on: overshoot urgency scale-up joint governance accelerated amidst present succinct account these insights, reflect their implications, offer integrated policy-relevant messages. science synthesis communication effort is also basis report contributing elevate every year time United Nations Conference. Social media highlight – more than 200 experts.
