Abstract: Present article sketches out major climate induced changes in marine, aquatic and terrestrial life. Few important biomarkers such as ecological, meteorological, socioeconomic, thermal, biophysical and biological, behavioral markers of climate change and global environmental stress have been highlighted to predict the future challenges and finding appropriate solutions. Though, so many climate change induced effects are visible but few unpredictable effects may be seen in future. Therefore, all such effects have been acknowledged, and tried to find appropriate solutions. Most visible effect is collection of high amounts of carbon dioxide in the atmosphere which is responsible for green house effect and causing natural calamities round the globe. It is not only jeopardized the survival of terrestrial, fresh water animals mainly planktons, bottom dwellers; coral reefs, algae, fish fauna in marine environment belong to different taxon but also responsible for disruption of ocean’s food web due to non-assimilation of extra carbon dioxide by the ocean water. There is a sharp decline in fresh water and sea shore micro-flora and micro-fauna. Other major visible effects are loss of biodiversity, depletion of forests, land degradation, severe floods and draughts. On other hand sudden changes in weather conditions causing irreparable devastations due to hurricanes and typhoons, storms, lightening, earthquakes and tsunamis are normally on rise. Both economic and ecological breakdowns are occurring more frequently which are more impactful and persistent. Climate change is major human health stressor; it is making fragmentation of socio-cultural bonds and reducing fertility of soil finally crop production. Climate change is imposing non-adaptive forced human migration, territorial conflicts, decreasing ecosystem productivity, disease out breaks, and impelling unequal resource utilization.
