By the end of 2020, due to extreme weather events, a record 55 million people have been forced to move within their own borders.
By 2020, the number of newcomers forced to move within their own country due to climate disasters will rise to the highest level in at least a decade, more than three times the number of newcomers displaced by conflict and violence.
According to the report of the Internal Displacement Monitoring Center, the number of people who have migrated in the country due to extreme weather events has increased to 30.7 million, accounting for 75% of the internally displaced persons within it. By the end of 2020, a total of 55 million people have been forced to migrate. Due to incomplete data, the number of climate migrants may be greatly underestimated.
Climate change is causing more frequent and intense weather events. According to the report, contrary to concerns about large-scale cross-border migration, many displacements are scaled and localized, costing the global economy US$20.5 billion by 2020.
Densely populated countries (such as China, India, the Philippines, and Bangladesh) are hit by strong hurricanes, monsoon rains, and floods, and during the most active Atlantic hurricane season on record, 1.7 million people have been displaced within the United States. According to the report, although the spread of the coronavirus has hindered the ability of humanitarian organizations to register and assist displaced persons, these records have been set.
