The primary consequence of climate change for arid regions is increased drought frequency and severity. As global temperatures rise, evaporation rates accelerate, leading to drier conditions and reduced water availability. This poses significant threats to agriculture, water supply, and natural ecosystems in these regions. Additionally, altered precipitation patterns can exacerbate desertification and habitat loss, impacting biodiversity and food security. Therefore, addressing climate change is crucial for mitigating its effects on vulnerable arid environments.
