Bangladesh suffers an annual economic loss of nearly $300 crore due to extreme climate events such as floods, droughts, storms, and heatwaves, impacting over 6.3 million people, according to the Climate Risk Index 2025 by Germanwatch. In 2022 alone, the country lost over $299 crore to natural disasters. However, effective risk prevention has drastically reduced cyclone-related deaths from 500,000 in 1970 to 4,234 in 2007. A 2022 heatwave, reaching 49.5°C in Pakistan and extending to India and Bangladesh, caused over 90 deaths. From 1993 to 2022, 9,400 extreme weather events globally led to 800,000 deaths and $4.2 trillion in damages. Global South nations, including Bangladesh, remain highly vulnerable. The report emphasizes that climate change is a growing global security threat, urging multilateral action to mitigate risks. Without intervention, extreme weather events will continue intensifying, further destabilizing societies and exacerbating global conflicts.
