- 5.6A: Climate change impacting the hydrological cycle
- Effects on inputs (precipitation)
- Climate change may lead to increased precipitation in some areas
- E.g. the Sahel region has had 5 wetter years since 1996, meaning there has been an increase in inputs in the local hydrological cycle
- This has had positives such as the regreening of the land
- This increases productive farmland, yield, as well as the natural regeneration of water-retaining shrubs
- This has had positives such as the regreening of the land
- E.g. the Sahel region has had 5 wetter years since 1996, meaning there has been an increase in inputs in the local hydrological cycle
- Tropical storms will also increase in frequency, as sea temps will rise
- Could reduce precipitation in areas used to high rainfall
- Intensity of heat waves has increased widely, especially in southern Europe and southern Asia, leading to greater drought occurence
- E.g. climate change is causing an increase in frequency of droughts in California
- Surface runoff an soil moisture levels declining, meaning forested areas are becoming grassland
- Snowpack levels at all time low in 2015, they provide 1/3 of California's water

- Climate change may lead to increased precipitation in some areas
- Effects on outputs (evaporation)
- Areas that see a rise in temperature will see an increase in evaporation
- Evaporation in large areas of Asia and North America is increasing
- If there is a decrease in temperature, these areas will see a reduction in evaporation
- Areas that see a rise in temperature will see an increase in evaporation
- Effects on inputs (precipitation)
