Climate change is increasingly affecting the globe, leading to a rise in extreme weather events such as floods, droughts, landslides, excessive rainfall, heat waves, and rising sea levels. Ignoring the reality of climate change can lead to disastrous consequences. Over the past two decades, India has seen significant shifts in its climate patterns during summer, monsoon, and winter, with unprecedented heat waves becoming a frequent occurrence.
In recent years, India has noted a marked increase in the number of three-day concurrent hot days and hot night events from 1951 to 2016. Heatwaves are expected to occur earlier, last longer, and become more frequent. The urban heat island effect exacerbates these impacts, resulting in heat-related deaths, heat stress, and the proliferation of vector-borne diseases. Vulnerable communities, particularly outdoor workers and those in inadequate housing, face significantly higher risks.
Impacted Regions: Heatwaves are particularly severe in central and northern India, notably in states like Rajasthan, Gujarat, Haryana, and Uttar Pradesh.
Unseasonal rainfall, such as the excessive rain in Delhi and the National Capital Region that caused the Yamuna River to breach its 1978 level, has led to catastrophic flooding. Eastern India has experienced unusually low rainfall, affecting regions accustomed to significant monsoon precipitation. Climate change has disrupted monsoon patterns, resulting in erratic dry spells and intense rainfall events that trigger floods. Coastal areas are particularly vulnerable due to rising sea levels and increased cyclonic activity.
Impacted Regions: Flooding has affected various parts of India, including areas along the Brahmaputra and Ganges rivers, and coastal regions like Kerala and Odisha.
Shifts in weather patterns have led to prolonged dry spells and altered monsoon cycles, causing droughts. These conditions severely affect agriculture and water resources, threatening food production and livelihoods. Changing precipitation patterns contribute to water scarcity, intensifying challenges for communities reliant on farming.
Impacted Regions: Drought conditions have been prevalent in states such as Maharashtra, Karnataka, Andhra Pradesh, and Telangana, severely impacting agricultural productivity and water availability.
Rising sea levels and increased cyclonic activity pose significant threats to coastal regions. Cyclones and tropical storms can inflict extensive infrastructure damage, displacing communities and disrupting daily life. The intensification of cyclonic activity is linked to rising global temperatures caused by carbon emissions.
Impacted Regions: Coastal areas along the Bay of Bengal, such as West Bengal, Odisha, and Andhra Pradesh, are highly susceptible to cyclones and tropical storms.
Altered precipitation patterns and increased rainfall can trigger landslides, especially in hilly areas. Landslides result in loss of life, property damage, and environmental degradation. The risks are heightened in regions with poor infrastructure and inadequate planning.
Impacted Regions: Hilly and mountainous areas, including the Western Ghats and the Himalayas, are prone to landslides, affecting states such as Kerala, Himachal Pradesh, and Uttarakhand.
The impact of climate change on India is profound and multifaceted. As temperatures rise and rainfall patterns become erratic, the challenges posed by extreme weather events and coastal vulnerabilities are significant. Immediate action, adaptation strategies, and international collaboration are essential to mitigate the impacts of extreme weather events and secure a sustainable future for all.
Q1. What are extreme weather events?
Answer: Extreme weather events are severe weather phenomena that deviate significantly from the average conditions. Examples include heatwaves, floods, droughts, and cyclones, often intensified by climate change.
Q2. How does climate change affect India?
Answer: Climate change impacts India through increased temperatures, erratic monsoon patterns, and a rise in extreme weather events, posing threats to agriculture, health, and infrastructure.
Q3. Which regions in India are most affected by heatwaves?
Answer: Central and northern regions like Rajasthan, Gujarat, Haryana, and Uttar Pradesh are particularly affected by heatwaves, experiencing higher temperatures and associated health risks.
Q4. What causes floods in India?
Answer: Floods in India are primarily caused by unseasonal rainfall, altered monsoon patterns, and rising sea levels, particularly affecting riverine and coastal regions.
Q5. How can communities prepare for extreme weather events?
Answer: Communities can prepare by developing disaster response plans, investing in resilient infrastructure, and raising awareness about the risks associated with extreme weather events.
