2030 and 2052. In order to limit the temperature increase to 1.5°C, global net anthropogenic carbon dioxide emissions must reach net zero by 2050. The Intergovernmental Panel on Climate Change notes in their 2023 report that the level of reduction in greenhouse gas emissions this decade will largely determine whether warming can be limited to 1.5°C or 2°C. (6) A 2023 report by the Intergovernmental Panel on Climate Change highlights that Deep, rapid, and sustained reductions in greenhouse gas emissions would lead to a discernible slowdown in global warming within around two decades, and also to discernible changes in atmospheric composition within a few years. . (7) The 2018 National Climate Assessment, authored by more than 300 experts and released by the United States Global Change Research Program, makes clear that the present unprecedented rises in global temperature are primarily due to human activities. The changing climate will devastate all sectors of society and disproportionately harm the most vulnerable communities. (8) Serious global warming impacts have already been observed in the United States and worldwide, including— (A) increases in heat waves and other extreme weather events
