WASH Services and Climate Change Impacts and Responses
Climate change is defined as a long-term change in the earth’s overall climate or in its various regional climates. These changes can be caused by processes inherent to the earth (solar activity, volcanoes, etc.), to the biosphere or to human activity. The changes currently taking place are mainly attributed to the human production of greenhouse gases, which include carbon dioxide (CO2) and methane (CH4), and which result in the warming of the atmosphere.

The impacts of global warming can be seen on different scales in all areas of the world. They affect both the environment and human societies at all levels (local, national, regional and global). Thus, the global rise in sea levels poses a threat to people and ecosystems in coastal areas. At the local level, droughts and heatwaves create an increased risk of water shortages. Heavy rainfall that leads to flooding can cause severe damage in urban areas and directly put people’s lives at risk.
