Climate Risk Index (CRI) 2025: India Among the Most Affected Nations Introduction to Climate Risk Index (CRI) The Climate Risk Index (CRI) 2025 is a globally recognized measure that ranks countries based on their vulnerability to extreme weather events over a defined period. This index assesses the impact of climate-related disasters such as floods, storms, heatwaves, and droughts. It serves as a critical indicator of how climate change affects human lives and economies across different regions. The CRI 2025 , published by German-watch , highlights India's growing vulnerability to climate-related disasters. India has been ranked as the 6th most affected country during 1993-2022 , highlighting the increasing frequency and severity of extreme weather events. Key Findings of CRI 2025 India's Climate Vulnerability India faced over 400 extreme weather events between 1993 and 2022 . The economic losses due to these disasters exceeded USD 180 billion . The death toll from climate-r...

Keeling Curve: Tracking the Rise of Atmospheric CO₂   In 2024 , atmospheric CO₂ levels reached a record high , driven by wildfires and human activities , as reported by the Keeling Curve . This alarming rise underscores the accelerating impact of climate change on our planet. What is the Keeling Curve? The Keeling Curve is a graph that tracks the concentration of carbon dioxide (CO₂) in Earth's atmosphere over time, measured in parts per million (ppm) . It is one of the most critical indicators of long-term climate change and global warming trends. Key Facts About the Keeling Curve When & Where Did It Begin? Continuous CO₂ measurements began in 1958 at the Mauna Loa Observatory, Hawaii . It remains the longest-running and most reliable dataset on atmospheric CO₂ levels. Who Developed It? ✔ Charles David Keeling , an American scientist, pioneered the first accurate measurements of atmospheric CO₂. ✔ His work proved the direct link between human activities and rising ...
