Also, IPCC Special Report on the difference in impacts between 1.5°C versus 2°C warming suggests that tropical countries such as India are projected to experience the largest impacts on economic growth because of climate change.
How will Climate Change-induced Warming Impact India?
According to a recent study by the Indian Institute of Tropical Meteorology (IITM), India’s average temperature has increased by about 0.7°C during 1901-2018, with more rapid warming in recent decades.
Agriculture: India's agriculture is heavily dependent on monsoon rains, and any alterations in rainfall patterns due to warming can significantly affect crop yields.
It would lead to erratic monsoons, increased frequency of droughts, and extreme weather events like heatwaves that will reduce agricultural productivity, posing a threat to food security and livelihoods of millions of farmers.
Public Health: Warmer temperatures may lead to the spread of diseases like malaria, dengue, and other vector-borne illnesses as the range of disease-carrying organisms expands.
Heatwaves can increase heat-related illnesses and mortality rates, especially among vulnerable populations, putting pressure on the healthcare system.
Ecosystems and Biodiversity: Warming can disrupt ecosystems and trigger shifts in vegetation patterns, altering habitats for various plant and animal species.
Many endemic species in India may face extinction or be forced to migrate to more suitable areas, leading to disruptions in the ecological balance and biodiversity loss.
Coastal Vulnerability: India has an extensive coastline, and rising sea levels due to warming can result in coastal erosion, inundation of low-lying areas, and increased frequency of extreme weather events like cyclones.
This poses a threat to coastal communities, infrastructure, and economic activities.
Migration and Social Disruptions: As climate-induced challenges intensify, there could be a rise in climate-induced migration, with people moving from severely impacted regions to more habitable areas.
This could lead to social tensions, resource competition, and strain on urban centers, leading to challenges for policymakers.
This includes creating green spaces, promoting public transportation, and incentivizing eco-friendly building designs to reduce the urban heat island effect.
Carbon Pricing: Introduce a carbon pricing mechanism to internalize the environmental costs of greenhouse gas emissions.
This could be achieved through carbon taxes or cap-and-trade systems to encourage industries to adopt cleaner technologies.
Promoting Circular Economy: There is a need to promote the adoption of a circular economy model, where waste is minimized, and resources are reused, repaired, or recycled, reducing the carbon footprint of products and processes.
