Climate Change: It is defined as long-term changes in the average climatic/weather conditions of the Earth’s environment. Anthropogenic activities such as fossil fuel combustion release greenhouse gases leading to global warming-induced climate changes in the average weather patterns of the Earth.
Global Climate Risk Index: This index represents the global report of nations that are facing extreme weather events due to human-induced climate changes. It points out the most vulnerable countries to climate change.
In this article top, 15 countries have been mentioned below that are already bearing the brunt of climate change. The countries are included in the rank order lists according to a score of climate risk index, average fatalities, average fatalities per 100,000 inhabitants, average economic losses in US dollars, and average losses per unit GDP in percentage.
The climate risk index (CRI) is calculated using all mentioned variables such as average fatalities among countries, average fatalities per 100,000 inhabitants, average economic losses, and average losses per unit GDP.
- Puerto Rico
Puerto Rico has ranked number first among the most affected countries by climate change. This country with a 7.17 CRI score is getting severely affected by extreme weather events in the last decade 2000-2019. The extreme weather events include intense tropical storms, sea-level rise, ocean acidification, and coral reef destruction, less precipitation, etc.
Myanmar has ranked number second among the most affected countries by climate change. This country with a 10.00 CRI score is facing impacts of climate change on the agriculture sector that might soon lead to food insecurity in the region.
Haiti has ranked number third on the list with a 13.67 CRI score. This country is getting hit by intense tropical storms such as hurricanes and cyclones that are resulting in less crop yield.
The Philippines is at fourth number in the list of most affect countries by climate change. This country with an 18.17 CRI score is prone to cyclones with extreme rainfall.
Mozambique has attained the fifth position in the list with a 25.83 CRI score. The country is facing frequent droughts, cyclones, heat waves, and floods due to climate change.
- The Bahamas
The Bahamas at number sixth a 27.67 CRI score is experiencing coastal erosion. Climate change is causing the sea-level rise and it will have severe impacts on the 80% of the land.
Bangladesh has secured the seventh number among the most affected countries by climate change with a 28.33 CRI score. The rising sea level is of the greatest concern for the country.
Pakistan at number eight with a 29.00 CRI score is facing the negative impacts of climate change. The extreme weather events in the country due to climate change are contributing to droughts, water crises, and famine.
Thailand is included in the list of the most affected countries by climate change. This country has been ranked at number nine with a 29.83 CRI score. The key issues are small changes in the weather pattern that are severely affecting the country. For instance, rising surface temperature will damage rice production.
Nepal with a 31.33 CRI score has got the tenth number on the list order. Climate changing is showing negative impacts on the country with wildfires and frequent droughts.
Dominica is a small country that has ranked number eleventh among the most affected countries by climate change. The CRI score of the country is 33.00. The damaged coastal agriculture lands have led to increased deforestation rates for agriculture purposes.
Climate change is affecting the coastlines of Madagascar and the country with a 34.67 CRI score has given twelfth position in the list of affected countries by climate change.
Vietnam is at number thirteenth with a 35.67 CRI score. This country is included in the list due to extreme weather events such as droughts, floods, landslides, and typhoons.
Cambodia has ranked number fourteenth among the most affected countries by climate change. This country with a 36.17 CRI score is experiencing frequent floods and droughts.
