Increased temperatures, rising sea levels and changes in rainfall are impacts of climate change, and they affect people living in poverty the worst – even though these people contribute the least to climate change. In many poor countries, these impacts of climate change have led to increasingly limited access to water, reduced crop yields, more widespread disease, increased frequency and intensity of natural disasters and conflict over declining resources – making the lives of the world’s poorest people even more precarious.
