Over the decade, between 2010 to 2019, weather-related events triggered an estimated 23.1 million displacements of people on average each year around the world. 

This figure was released by the World Meteorological Organization (WMO) in its provisional report published in January. 

Most of these displacements took place within national borders, but sometimes people obliged to leave their countries. In the first half of 2020, 9.8 million displacements occurred due to meteorological disasters, mainly in South-east Asia and the Horn of Africa. In the second half of 2020, due to disasters in the Sahel region, the hurricane season in the Atlantic and typhoons in South-east Asia, the number of displacements is expected to equal the average for the decade. 

These severe weather events are now occurring on a planetary scale. Some countries have been particularly affected: Bangladesh, China, India, Japan, Pakistan, Nepal, South Korea, Turkey, Vietnam, Philippines, Australia, United States, Canada, Mozambique, Somalia, Ethiopia, Tchad, Yemen, Syria.   

The World Meteorological Organization has also released its annual state of the Global Climate 2020. 

Among the highlights, the WMO pointed these main observations: 

  • The 2011-2020 decade is the hottest in history. 
  • Greenhouse gases increased in 2020 despite the economic slowdown caused by the pandemic. 
  • The Arctic and Antarctic are warming twice as fast as the global average. 
  • The warming of the oceans continues at all depths. 

Against this background, the scientists participating in the report predict a deterioration of the following conditions: 

  • Ocean levels will continue to rise, and so will the threat of coastal erosion. 
  • Extreme severity weather events have intensified over the decade and will continue to do so. Across the planet, we will see more floods, forest fires, droughts, heat waves, cold spells, and severe storms.
