The document emphasizes the urgent need for increased climate finance to support the world's poorest and most climate-vulnerable countries, which are disproportionately affected by climate change yet contribute the least to the crisis. It highlights that only a small percentage of climate finance is allocated for adaptation efforts related to water and sanitation, putting billions at risk and exacerbating existing inequalities. Clean water access is framed as a critical line of defense against climate impacts, with insufficient funding and poor resource allocation threatening the health and safety of these communities.
