Abstract Climate change implies change in climate as a result of direct or indirect interference of human activities i.e. anthropogenic activities resulting in the change in composition of global atmosphere and climate variability over a comparable period of time. It has been found that global temperature hiked by 0.8°C and is believed to reach 1.1-5.4°C by the 25th century. On the contrary, CO2 concentration has reached to 370ppm from 280ppm which indicates a drastic change in the concentration of CO2. The factors like volcanic eruptions, oceanic currents, the orbital movements of the earth and other anthropogenic activities are the reasons for this shift. Change in climate results in a number of changes in insect pollinators such as changes in insect phenology, distribution, biodiversity and interactions with plants. In addition to this climate change is also responsible for habitat loss, nutritional inadequacies and lack of diverse food due to effect of climate change on plant and flower growth. Hence, climate change negatively effects plant and pollinator interactions. As most of the flowering plants are in need of insect pollinators for reproduction and fruit and seed set. Therefore, conservation and protection of these pollinators are prime need for food security and the knowledge on the effect of climate change on pollinators and evolve suitable mechanization to prevent them from getting affected by this climatic modification.
