Climate change or global warming, as it is popularly known, is a global phenomenon requiring global solution. The phenomenon is happening due to greenhouse gas emission and other industrial pollutants. The climate change is widely felt with respect to increased surface temperature, which is around 0.6oC. This climate change that is affecting every walk of life also has a major impact on agriculture. Pesticides are applied to protect the crop form insects, pathogens and weeds. However, less than percent of the applied pesticides reach the targets pests. Pesticides as a chemical substance interact with these non target sectors of environment in many different ways and alter ecological stability and diversity, nutrient cycle, energy flow. Once a pesticide is introduced into the environment, it is influenced by many processes such as sorption (desorption, degradation (biological and abiotic), and volatilization and their off-site transport into surface and ground water. All these processes are affected by climatic factors. Extreme climate changes alter the kinetics and persistence and dissipation of pesticides in the environment. Basic information is required on the impact of climate change and variability on the fate of pesticides in the environment.
