摘要

In 2013, NASANational Aeronautics and Space Administration (NASA) (National Aeronautics and Space Administration) (NASA Responding to Climate Change in https://science.nasa.gov/climate-change/adaptation-mitigation/ ) warned that ‘the daily level of carbon dioxide in the atmosphere surpassed 400 parts per million for the first time in human history. The last time levels were that high was about 3–5 five million years ago, during the Pliocene Epoch’. The 2014 report of the IPCC: Impacts, Adaption and Vulnerability proposed ways governments and societies could prepare for the challenges of global warming, such as changing the types of crops to grow in hotter and more humid climates, and designing buildings in more ecologically-friendly ways. The long-term issue is how far does adjustment imply a basic resignation and an accommodation to climate change, or can it become part of an environmental turnaround. A starting point, according to the IEAInternational Energy Authority (IEA), is that pledges by countries cover less than 20% of the reductions in GHG emissions needed by 2030 to keep the path on track towards the Paris goals, especially now that 1.5C has been exceeded in every month since mid-2023 (IEA (2023) World Energy Outlook 2023: Executive Summary in https://www.iea.org/reports/world-energy-outlook-2023/executive-summary ).
