The world is entering what scientists describe as one of the most dangerous climate periods in modern history, as rising global temperatures and the growing possibility of a powerful El Niño raise concerns about extreme weather events across the planet.
Climate experts from international agencies, including the World Meteorological Organization (WMO), have warned that ocean temperatures in the Pacific are rising rapidly, increasing the likelihood of El Niño conditions developing later this year. Scientists fear that when combined with human-driven global warming, the phenomenon could intensify heatwaves, droughts, floods and storms worldwide.
El Niño is a natural climate pattern caused by unusually warm surface waters in the Pacific Ocean. While it has occurred throughout history, researchers say its impacts are becoming more severe because Earth itself is already significantly warmer due to greenhouse gas emissions produced by burning fossil fuels such as coal, oil and gas.
According to recent climate data, the planet has already warmed by approximately 1.4°C above pre-industrial levels. Scientists warn that the Earth is now dangerously close to crossing the critical 1.5°C warming threshold set under the Paris Climate Agreement.
The 1.5°C limit is considered a major warning line by climate researchers because warming beyond this level could sharply increase the risks of irreversible environmental damage. Experts say even small increases in global temperature can intensify extreme weather patterns, disrupt food and water supplies, accelerate glacier melting and threaten ecosystems across the world.
Recent years have already provided a glimpse of these dangers.
Across multiple continents, extreme heatwaves have shattered temperature records. Wildfires have spread through forests and dry regions at unprecedented speed, while heavy rainfall and flash floods have devastated cities and rural communities alike. Scientists say warmer oceans and atmosphere hold more energy and moisture, making storms more destructive and rainfall more intense.
For India, the threat is particularly serious.
Climate scientists have long linked El Niño years with weaker monsoon rainfall, prolonged dry periods and rising summer temperatures. If a strong El Niño develops alongside continued global warming, India could face intensified heatwaves, water shortages, agricultural stress and disruptions to food production.
Researchers warn that vulnerable populations, especially farmers and low-income communities, are likely to suffer the most severe consequences.
The WMO has stated that the years between 2015 and 2025 were the hottest ever recorded globally. Scientists also estimate there is a strong probability that at least one year before the end of this decade could temporarily exceed the 1.5°C warming mark.
Environmental experts say the primary driver behind modern climate change remains the large-scale use of fossil fuels. Carbon dioxide and other greenhouse gases released into the atmosphere trap heat around the planet, steadily increasing global temperatures.
United Nations Secretary-General António Guterres recently warned that “every key climate indicator is flashing red,” urging governments to rapidly reduce emissions before climate impacts become even more difficult to control.
Scientists emphasize that the situation is serious but not irreversible. They argue that immediate reductions in fossil fuel consumption, expansion of renewable energy, forest protection and sustainable development policies could still slow warming and reduce the risk of future climate disasters.
However, researchers caution that time is running out.
As oceans continue to warm and climate systems become increasingly unstable, scientists say humanity is approaching a defining moment in its response to the climate crisis one that could shape the future of the planet for generations to come.
