Satellite data shows marine life is already declining as El Niño strengthens. What’s happening beneath the waves? When trade winds flip and deep nutrient-rich waters stop rising, phytoplankton die off; which means less food for fish, less oxygen in the ocean, and a ripple effect that reaches our rainy season. The monsoon is already 15% below average this year. If El Niño gets worse, expect drier spells, crop stress, and tighter water supplies. This isn’t just ocean science; it’s farm science, food security, and your next summer’s water bill. ISRO’s sensors are quietly tracking what could be India’s biggest climate challenge in 2026. And they’re not just watching; they’re warning.
