Climate Change Impact Analysis

The pursuit of creating a developed world with high living standards has led to numerous human activities that have resulted in climate changeClimate change. Despite improvements in living standards, the repercussions of climate changeClimate change have threatened the world's sustainability. One significant impact is on water resources, as climate changeClimate change alters water dynamics and distributionDistribution across space and time. Many organisations have developed state-of-the-art climate models to understand climate changeClimate change better, and collective efforts are being made to improve our understanding of various Earth processes to refine existing models. With advancements in scientific understanding and computational power, new developments are being made in climate modelling and climate changeClimate change studies. These include designing mechanisms for future trajectories in a warming world and regularly supplementing them with new information. The efforts of the Intergovernmental Panel on Climate Change (IPCCIntergovernmental Panel on Climate Change (IPCC)), from their First Assessment Report (FAR) to their most recent Sixth Assessment Report (AR6), are evidence of this scientific development. Understanding climate changeClimate change and climate data handling is now a prerequisite for researchers in water resources. This chapter provides an overview of various concepts related to climate changeClimate change, climate models, climate data downscalingDownscaling, and the state and fate of water resources in the changing climate.
