The recorded data on climate change over the past century indicate the increase in temperature. Important Biological events, including changes in plant/vegetation/crop phenology, have been investigated globally and found to be intimately as well as inextricably linked with climate change. Timing of life cycle events in relation to environment is phenology. Plants are finely tuned to the seasonality of their environment, and shifts in the phenology provide some of the most compelling evidence that species and ecosystems are being influenced by global climate change. Increase in temperature plays a vital role in germination, vegetative growth flowering and fruiting of plants. Climate change also perturbs the phenology of crop plants intimately linked with socioeconomic livelihood and should be given particular focus in future research. Concomitantly phenology may be linked with ecosystem as well as community dynamics. Future studies should aim to quantify and understand the effects of earlier leaf unfolding and later leaf fall on temperature, soil moisture, and atmospheric composition and dynamics. Moreover, long term data of climate change and its interrelationship is required to predict impact of climate change on phenology and vice versa. Also, modern tools like remote sensing may also play a crucial role in the present context.
