Pricing rainbow, green, blue and grey water: tree cover and geopolitics of climatic teleconnections

- Atmospheric moisture, as rainbow water, is influenced by terrestrial evapotranspiration.
- Trees influence green, blue and rainbow water parts of the hydrological cycle.
- Influence of tree cover on terrestrial rainfall and water cycle critically depends on location.
- West African rainfall, esp. in Sahel, depends on East African evapotranspiration.
- Geopolitical consequences of these types of forest-climate relations are yet to be explored.
