Which areas are most highly and quickly affected by an increase in carbon emissions?

Areas most quickly and highly affected by an increase in carbon emissions include coastal regions, which face rising sea levels and increased flooding, and urban centers, where air pollution and heatwaves can exacerbate health issues. Ecosystems such as the Arctic are also rapidly impacted, experiencing accelerated ice melt and habitat loss. Additionally, regions dependent on agriculture may suffer from altered weather patterns, leading to crop failures and food insecurity.
