As per a report published by the United Nations Office for Disaster Risk Reduction (UNISDR), on Monday, 90% of natural disasters that took place in the last 20 years were weather-related.

The global catastrophes, including floods, heat waves, extreme cold, storms and droughts have taken more than 600,000 lives and affected an average of 4 billion people across the globe.

While making this report, the UNISDR in partnership with the Belgian-based Centre for Research on the Epidemiology of Disasters (CRED) collected and analyzed data since the first Climate Change Conference that held in 1995.

The report said that every year between 1995 and 2015,an estimated 205 million people were left homeless, got wounded or required emergency assistance due to 6,457 weather-related disasters.

The hardest hit continent was Asia, with frequent events and the highest number of people killed, as it has a huge and extensive diversity of landmass and zones vulnerable, like multiple river basins and flood plains.

Moreover, the continent has high population densities in areas prone to natural hazards. In the last decade, a total of 2,495 weather-related disasters have taken placejust in Asia, and left 3.7 billion people without home and 332,000 deaths.

After Asia, comes USA and China with the highest numbers of weather-related disasters because of high population concentrations and huge heterogeneous landmasses, with 472 and 441 respectively. These countries are followed by India (288), Philippines (274), and Indonesia, (163). Most of the lives were taken by storms like hurricanes, which claimed over 12,000 lives every year.
