In 2018, the IPCC had warned that if, by 2030, the world failed to cut emissions by half of the levels in 2010, there was little chance of limiting warming to 1.5°C over pre-industrial levels by the end of the century. The reality, however, is emissions continue to rise, despite the much-publicised climate-action commitments (including Net Zero announcements) of both developed and developing countries. IPCC assessment reports typically take six-to eight years to put together; so, AR6 is very likely the last before 2030, by when the window for action to stay on the 1.5°C pathway would have closed.
