Climate change may turn India's rivers into hostile environments for aquatic life by 2070-2100. River water temperatures may increase during the period and dissolved oxygen levels may decrease. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities. As climate change worsens, dangerous weather events are becoming more frequent or severe. The main threats of climate change, stemming from the rising temperature of Earth's atmosphere include rising sea levels, ecosystem collapse and more frequent and severe weather. Rising temperatures from human-caused greenhouse gas emissions affects planet-wide systems in various ways.

Climate change has significant impacts on the river systems in India. One of the most significant impacts is the alteration of the timing and magnitude of river flows. Climate change is causing changes in rainfall patterns, leading to more extreme weather events such as floods and droughts. This has a significant impact on the flow of rivers in India. Floods can cause significant damage to infrastructure, homes, and agricultural land. In addition, it can cause erosion and sedimentation in rivers, leading to changes in their morphology and flow patterns. Droughts, on the other hand, can cause water shortages, affecting the availability of water for agriculture, drinking, and other purposes. Moreover, climate change is also causing the melting of glaciers in the Himalayas, which are a significant source of water for many of India's rivers. The loss of glacier mass is leading to changes in the timing and magnitude of river flows, affecting the availability of water for irrigation and other uses. Climate change also has a significant impact on the environment in India. Changes in temperature and rainfall patterns can affect ecosystems, leading to the loss of biodiversity and changes in the distribution of species. Changes in temperature can also lead to the spread of diseases and pests, affecting both human and animal populations. The rise in sea level due to climate change can also have a significant impact on coastal areas, causing flooding, erosion, and saltwater intrusion. This can affect the livelihoods of people living in these areas, who are often dependent on fishing and other coastal activities. In summary, climate change is having a significant impact on the river systems in India, affecting the timing and magnitude of river flows, and leading to floods and droughts. Climate change also affects the environment, leading to changes in ecosystems, the spread of diseases and pests, and affecting coastal areas.
