ABSTRACT
The three successful special climate summits, the strongly successful Group of Seven countries (G7) summit and the potentially productive Group of twenty countries (G20) and United Nations (UN) summits in 2021 gave some hope that the global governance of climate change would work as never before. This began with the solid performance of the One Planet Summit on Biodiversity and continued with the additional advances at the Climate Adaptation Summit in January, and the strong performance of Joe Biden's Leaders Summit on Climate in April, with 40 major leaders. An economically growing China and reviving United States with world-leading emissions understood that they must cooperate and converge to confront the shared, existential threat of climate change. It remained to be seen if deadly extreme weather events fuelled by climate change and ominous scientific evidence escalating through the autumn could force the combined leadership from the G7, G20, UN and special climate summits to produce a genuine physical and human success.
