The Atlantic and Pacific oceans are simultaneously driving some of the world most severe weather extremes with scientists warning that shifting ocean conditions are exposing billions of people to dangerous heatwaves delayed monsoons and worsening climate risks.
According to climate experts the warming Atlantic Ocean is intensifying powerful heat domes over Europe and North America, sending temperatures soaring to record levels. At the same time, the Pacific Ocean is witnessing the development of a strengthening El Nino, which is weakening India’s southwest monsoon and contributing to one of the country’s sharpest rainfall deficits in recent years.
These two large scale oceanic changes are influencing weather patterns across continents creating a chain reaction that stretches from New Delhi to New York.
Heat domes intensify as Atlantic Ocean warms
Scientists say unusually warm Atlantic waters are providing extra energy to the atmosphere, strengthening high pressure systems known as heat domes. These systems trap hot air over large regions for several days, causing prolonged and intense heatwaves.
Across Europe and North America, soaring temperatures have increased health risks, strained electricity supplies and raised concerns over wildfires and drought. The persistent heat has also affected agriculture, water resources and public infrastructure in several countries.
Climate researchers note that warmer oceans are making such extreme heat events more frequent and more intense as global temperatures continue to rise.
El Nino weakens monsoon, raising concerns for India
While the Atlantic influences heat in the West, the Pacific Ocean is reshaping weather across Asia. A strengthening El Niño has begun weakening the southwest monsoon, reducing rainfall over large parts of India.
Meteorologists say the delayed and weaker monsoon has resulted in a significant rainfall deficit, increasing pressure on agriculture, reservoirs and drinking water supplies. Farmers dependent on seasonal rainfall are facing uncertainty, especially in regions already vulnerable to drought.
Experts warn that if El Nino continues to strengthen during the season, India could experience prolonged dry conditions, affecting crop production, food security and rural livelihoods.
Climate scientists emphasise that oceans play a central role in regulating Earth’s weather systems and changes in sea surface temperatures can influence rainfall, storms and heatwaves thousands of kilometres away. They caution that as climate change warms the oceans further, the interaction between oceanic cycles and global warming could make extreme weather events more severe and more unpredictable.
Researchers say understanding these interconnected ocean systems will be essential for improving weather forecasting, disaster preparedness and climate adaptation as the world faces increasingly volatile weather patterns.
