A total of 188 scientists and ecologists in India have issued an urgent appeal for researchers to prepare for an upcoming extreme weather pattern in the Pacific Ocean. In the region where the weather event originates, water temperatures have steadily climbed past the normal limit since May 2026, hitting +2.6°C by August. Forecasts suggest temperature anomalies could reach up to +4°C, which is higher than anything recorded in the past 1,000 years based on data from coral cores. The main effects are expected to hit India from November 2026 onwards and last at least until March 2027, bringing hot and dry conditions along with weak monsoons. Experts warn that India's natural systems face severe threats over the coming months. Projected impacts include widespread coral bleaching and death, an increase in wildfires, and the loss of large rainforest trees. Farmers, fishers, and shepherds face a high risk of drought and extreme heat. Less visible effects, such as delayed fruit production and changes in animal behavior, are also expected. The 'Call to Action' document urges researchers to document these changes to help build a climate-resilient future for the country. Jayashree Ratnam from the National Centre for Biological Sciences noted that many large trees in the Western Ghats and in cities are already close to their heat tolerance limits. Rohan Arthur, a marine biologist with the Nature Conservation Foundation, pointed out that the projected scale of the heatwave is particularly alarming because coral reefs need at least a decade to recover after a major die-back, and the last major event occurred only two years ago in 2024. Roxy Mathew Koll from the Indian Institute of Tropical Meteorology added that the current monsoon season is ending with a rainfall deficit, and these impacts will likely cascade through depleted soil moisture, land and marine heatwaves, and stressed livelihoods.

ExplainerWhy this matters

What Happened

Nearly 190 Indian scientists and ecologists have released a joint appeal urging fellow researchers to monitor and document the severe ecological impacts of an upcoming, highly intense Pacific Ocean weather cycle set to affect the subcontinent from late 2026.

Why It Matters

This projected event carries temperatures higher than any seen in the past millennium. It threatens critical ecosystems like coral reefs and rainforests, while jeopardizing the livelihoods of farmers, fishers, and shepherds through heightened risks of drought, extreme heat, and agricultural stress.

What Happens Next

Researchers must mobilize quickly to track ecological changes as they unfold from November 2026 onward, while working to safeguard remaining ecosystems and reduce existing environmental pressures to prepare India for a warmer future.
