Drought can both be an effect of climate change and contribute to its further intensification. As global temperatures rise, evaporation rates increase, and more water is pulled from soil and vegetation, leading to increased risk and severity of drought.
When drought occurs, it can have several impacts on the environment and human society, including:
- Reduced agricultural productivity and food shortages
- Increased wildfire risk
- Higher energy demands for water pumping and cooling, leading to increased greenhouse gas emissions
- Reduced water availability for households, agriculture, industry, and ecosystems
- Changes in land use patterns, such as increased urbanization and deforestation, can further exacerbate the effects of drought on the environment.
Moreover, prolonged droughts can cause a feedback loop that exacerbates climate change. When vegetation dies and the ground dries out, it becomes more difficult for the soil to absorb water when it finally does rain, leading to more runoff and erosion. This can cause soil carbon to be lost and contribute to carbon emissions.
Overall, droughts are both a consequence and a contributor to climate change, and mitigating their effects requires a comprehensive approach that addresses the root causes of climate change.
Hope that helps! Good luck! :)
