India is heading into one of its hottest years on record, with meteorologists predicting severe heatwaves and soaring temperatures across the country in 2025. February 2025 was officially Delhi’s warmest in 74 years, and forecasts suggest that March will be significantly hotter than usual, bringing an increased number of heatwave days.Climate experts warn that 2025 could surpass 2024 in terms of extreme temperatures, highlighting rising global warming trends. With greenhouse gas emissions continuing to rise, the effects of climate change are becoming more evident across India and the world.
 

Rising Temperatures and Heatwave Warnings Across India

According to data from the Copernicus Climate Change Service (C3S), global temperatures in January 2024 were 1.75°C above pre-industrial levels, moving further away from the Paris Agreement’s goal of keeping global warming below 2°C. The World Meteorological Organization (WMO) has warned that 2025 could mark the third consecutive year of extreme heat, driven by both human activity and natural climate factors.
 

India is already seeing the impact of these rising temperatures. Mumbai recently recorded temperatures above 37°C, while the India Meteorological Department (IMD) predicts that in 2025, Bengaluru could be hotter than Delhi, a significant and unprecedented shift in climate patterns.The increasing frequency and intensity of heatwaves have become a major concern. Defined as prolonged periods of extreme heat, heatwaves have affected 125 million more people between 2000 and 2016, according to the World Health Organization (WHO). The IMD forecasts that 2025 will bring record-breaking heatwaves, especially in northern and central India, putting millions at risk of heat stress, dehydration, and health complications.
 

Glacier Melting, Rising Sea Levels, and Climate Consequences

The impact of rising temperatures extends far beyond heatwaves, as melting glaciers and rising sea levels pose significant threats to coastal regions and global ecosystems.

• Venezuela became the first country to lose all of its glaciers due to global warming, a stark warning of what could happen elsewhere if temperatures continue to rise.
• A study published in Nature found that 36% more ice was lost between 2012 and 2023 compared to previous decades, accelerating sea level rise and threatening low-lying regions.
• Melting glaciers contribute to coastal erosion, habitat loss, and an increased risk of flooding, which could displace millions of people in the coming decades.

Aside from environmental concerns, extreme weather events fueled by climate change are having severe economic and social consequences.

• Agriculture is suffering due to unpredictable rainfall patterns and prolonged dry spells, leading to lower crop yields, food shortages, and rising prices.
• Heat stress is affecting productivity in labor-intensive industries, slowing down economic growth.
• Forest fires are increasing, leading to loss of biodiversity and destruction of natural carbon sinks, which further accelerates climate change.
• Climate migration is rising, as people are forced to leave their homes due to droughts, floods, and extreme heat conditions.

Urgent Need for Climate Action and Policy Changes

As the crisis worsens, governments and organizations worldwide must take immediate action to combat climate change and mitigate its effects.

• The transition to renewable energy sources needs to accelerate while ensuring sustainable mining practices for resources like lithium and cobalt.
• Governments must enforce stricter emission regulations to curb greenhouse gas emissions and reduce reliance on fossil fuels.
• Investment in climate-resilient infrastructure is crucial, particularly in regions vulnerable to heatwaves, droughts, and sea level rise.
• Public awareness campaigns should educate people on climate adaptation strategies, including water conservation, afforestation, and sustainable urban planning.

If urgent climate action is not taken, 2025 could set new temperature records, worsening the challenges faced by both people and ecosystems worldwide. The time to act is now to prevent further damage and secure a livable future for the next generations.
