In March 2023, with the publication of the so-called Synthesis report, the IPCC completed its Sixth Assessment cycle. During this cycle, which started in 2015, the IPCC published three special reports: Global Warming of 1.5 °C in October 2018; Climate Change and Land in August 2019; and Special Report on the Ocean and Cryosphere in a Changing Climate in September 2019. These reports were followed by reports of three Working Groups. The Working Group I contribution to AR6, Climate Change 2021: the Physical Science Basis, was released on 9 August 2021. The Working Group II contribution, Climate Change 2022: Impacts, Adaptation and Vulnerability, was released on 28 February 2022. The Working Group III contribution, Climate Change 2022: Mitigation of Climate Change, was released on 4 April 2022. The cycle was then completed with the AR6 Synthesis Report, Climate Change 2023.
