'Climate change' is a global problem. How India will be affected by climate change? How Himalayan and coastal states of India will be affected by climate change?
Climate change is referred to a change in average weather conditions, or in the time variation of weather within the context of longer-term average conditions. Climate change has attracted attention recently particularly due to the changes apparent from the mid to late 20th century onwards and it is attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
- India due to its peculiar geography and developmental stage is one of the most vulnerable nations to climate change.
- India is already experiencing a warming climate and erratic monsoon pattern, unpredictable rainfall since last few years.
- Droughts are expected to be more frequent in some areas, especially in north-western India, Jharkhand, Orissa and Chhattisgarh.
- Climate change is expected to have major health impacts in India- worsening the already high malnutrition and related health disorders such as child stunting - with the poor likely to be affected most severely.
Possible effects on Himalayan states
- With rise in average temperature, most Himalayan glaciers have been retreating over the past century. This may have severe impact on the delicate Himalayan ecology.
- The melting of glaciers and the loss of snow cover over the Himalayas is expected to threaten the stability and reliability of northern India’s primarily glacier-fed rivers systems, particularly major river systems like the Indus, the Ganges and the Brahmaputra. This will adversely impact the ecology, livelihood and overall economy of Himalayan states.
Possible effects on coastal states
- India is close to the equator, the sub-continent would see much higher rises in sea levels in comparison to higher latitudes and most of coastal states will face the heat of climate change.
- Kolkata and Mumbai, both densely populated cities, are particularly vulnerable to the impacts of sea-level rise, tropical cyclones, and riverine flooding
- Sea-level rise and storm surges would lead to saltwater intrusion in the coastal areas, impacting agriculture, degrading groundwater quality and contamination of drinking water.
Being one of the most vulnerable countries to climate change, it is high time that India should take corrective and mitigating actions to cope up with the upcoming challenges of climate change.
