Erratic Monsoons and Rising Temperatures Fuel Deadly Floods in South Asia
July 11, 2025 — As monsoon rains sweep across South Asia from June to September, the region faces growing devastation instead of relief. Fueled by rising global temperatures, rainfall is becoming more intense and unpredictable, triggering deadly floods, glacial lake overflows, and landslides across India, Nepal, Pakistan, and beyond.
In 2024 alone, nearly 1,300 people died in India due to rain-related disasters. Hundreds more have died across the region in 2025. Climate experts warn that higher temperatures are melting Himalayan glaciers faster, with at least 200 glacial lakes now at risk of overflowing, according to the International Centre for Integrated Mountain Development.
“The monsoon is no longer steady – it’s now marked by intense downpours and long dry spells,” said Dr. Roxy Mathew Koll, a climate scientist in Pune. “Urban flooding, overwhelmed infrastructure, and crop failures are becoming the new normal.”
More than 60% of South Asia’s population depends on monsoon-based farming, now threatened by both flooding and drought. Experts urge early warning systems, better urban planning, and most importantly, cuts to greenhouse gas emissions.
“There are limits to how much we can adapt,” said glaciologist Miriam Jackson. “Without climate action, the disasters will only worsen.”
