Floods in Himachal, Delhi: What's the Climate Connection? | 🎙️ 5-Min Climate-Weather Report

Learn how the warming atmosphere and increased moisture capacity contribute to heavier and more intense rainfall in Northwest India. The recent disasters confirm the vulnerability of hilly regions to the orographic effect, where global warming amplifies the effects of heavy rains and landslides. 

The recent devastating floods in Himachal Pradesh and the rising water levels in Delhi have highlighted the severe impact of climate change on our weather systems. In Himachal Pradesh, torrential rainfall triggered landslides and flash floods, causing widespread destruction and claiming the lives of 91 people. The state has also suffered a significant monetary loss of over Rs 2000 crores in just 20 days.

Meanwhile, Delhi experienced its highest recorded rainfall in the past 40 years, with 153 mm of rain within 24 hours. The heavy rains in Himachal Pradesh and Haryana led to increased water levels in the Hathnikund barrage, which was released towards Delhi, resulting in flood-like conditions. The water level of Yamuna reached its highest in 45 years, breaching the river embankment and causing evacuations in low-lying areas.

Experts attribute these recurring disasters to climate change, which has made extreme rainfall events more frequent. The Himalayan region, including Himachal Pradesh and Uttarakhand, is particularly vulnerable to climate change impacts. The warming atmosphere has increased moisture capacity, leading to heavier and more intense rainfall. The hilly terrain exacerbates the effects, as the orographic effect lifts up the moisture-laden air, resulting in incessant rains.

These recent events serve as a stark reminder of the urgent need to address climate change and its impacts. As extreme weather events become more common, it is crucial to take immediate action to mitigate climate change and build resilient communities that can withstand the challenges of a changing climate.
