This episode will explore how climate change will cause substantial changes in precipitation patterns, and factors such as surface temperature that govern evapotranspiration. 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. You will also learn how changes in annual water runoff are expected to be amplified once warming has reached 4°C compared to 2°C. This result means that regions with dry conditions will become drier, and regions with wet conditions will become wetter.
