The world is warming at an unprecedented pace and humaninduced climate change has already caused widespread adverse impacts on people and nature (IPCC, 2022e). There are already observed increases in frequency and intensity of climate and weather extremes in every inhabited region of the world, including heat waves, heavy precipitation events that cause flooding, drought and fire and this is expected to intensify (IPCC, 2022e). Progress on the Sustainable Development Goals has been inhibited and the most vulnerable people are disproportionately affected (IPCC, 2022e). This is only the beginning as global temperatures will continue to rise until at least the middle of the 21st century in all currently possible emission scenarios. If deep emission cuts do not occur, the temperature will rise at least 2.1°C to 3.5°C or even up to 5.7°C by the end of the century (IPCC, 2021).
