Climate change, a term frequently echoed in scientific discourses and public debates, has become one of the most pressing issues facing humanity today. This phenomenon involves significant alterations in global temperatures and weather patterns over time. Although climate change is a natural process, scientific evidence strongly indicates that human activities have significantly accelerated these changes, leading to adverse environmental, economic, and social consequences.
Climate change is a global challenge that requires collective efforts to mitigate its impact and ensure a sustainable future. India, as one of the world’s most populous countries and a rapidly growing economy, has taken significant strides toward climate action. From implementing policies to adopting clean energy solutions, the nation is committed to decarbonisation and creating a low-carbon future.
Key Drivers of Climate Change
- Greenhouse Gas Emissions:
The burning of fossil fuels (coal, oil, and natural gas) for energy and transportation releases carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and other greenhouse gases (GHGs) into the atmosphere. These gases trap heat, leading to the greenhouse effect, which warms the planet.
- Deforestation:
The clearing of forests for agriculture, urban development, and logging reduces the number of trees that can absorb CO2, thus increasing the concentration of CO2 in the atmosphere.
- Industrial Processes:
Various industrial activities release GHGs and other pollutants. For instance, cement production emits a significant amount of CO2.
- Agricultural Practices:
Certain agricultural methods, such as rice paddies and livestock farming, produce methane. Fertilizers and other agrochemicals also release nitrous oxide.
Current Status of Climate Change in India
India’s commitment to addressing climate change is reflected in its Nationally Determined Contributions (NDCs) under the Paris Agreement. The country has pledged to reduce its carbon intensity and enhance its share of non-fossil fuel energy capacity by 2030. With its vast renewable energy potential, India has emerged as a global leader in the deployment of renewable energy sources like solar and wind.
Environmental Impacts
- Rising Temperatures:
Global temperatures have risen approximately 1.2°C above pre-industrial levels. The past decade has been the warmest on record, with 2020 and 2021 among the hottest years ever documented.
- Melting Ice and Rising Sea Levels:
The Arctic sea ice is shrinking, glaciers are retreating, and the Greenland and Antarctic ice sheets are losing mass. Consequently, global sea levels have risen by about 20 centimeters since the late 19th century, with projections of further rises threatening coastal communities and ecosystems.
- Extreme Weather Events:
The frequency and intensity of extreme weather events, such as hurricanes, heatwaves, droughts, and heavy precipitation, have increased. These events cause significant damage to infrastructure, agriculture, and human lives.
- Ocean Acidification:
Oceans absorb about 30% of the CO2 emitted by human activities. This absorption leads to ocean acidification, which adversely affects marine life, particularly organisms with calcium carbonate shells and skeletons, like corals and shellfish.
Economic and Social Impacts of Climate Change
