Risk to Global Water Resources
The changes in the terrestrial water cycle are likely to affect the nature and availability of natural water resources and the human societies that rely upon them for food production. The episode also discusses projected intensification of impacts for various level of warming by 2100, i.e. how in a 4°C world, climate changes would become large enough to dominate changes in water stress in dry regions and that it is very likely that many countries that already face water shortages today will suffer from increased water stress in a 4°C world.
