Extreme weather events have significant consequences. A ranking system assesses the impact of these events on countries. This system has been in place since 2006 and provides a yearly evaluation of climate-related effects.

The evaluation considers various factors, including the number of people affected and economic losses. Countries are then ranked based on these factors, with the most affected country given the highest ranking. Further details about the ranking system and its findings are available from the source, which publishes an annual index of climate-related impacts.
