In 2018, the Intergovernmental Panel on Climate Change published its report on global warming of 1.5°C, which clearly illustrated why the 1.5°C warming limit set out in the Paris Agreement is so important. Warming above 1.5°C would raise the likelihood of experiencing severe and even irreversible impacts, and could push people and ecosystems beyond limits to adaptation. Capping warming at 1.5°C would lower the risk of crossing dangerous tipping points, and maintain the effectiveness of a wider set of adaptation options. With these graphs, you can explore how the severity of heat-related climate change impacts across the world change with the level of climate action
