Answer:
Climate change means a change in the state of the climate system that is sustained over a long period of time. These types of changes can occur due to natural or human causes.
Climate change and its effects on the planet can generate massive migrations, given the affectation of nature in certain parts of the planet.
Thus, an example would be the migration of populations from island countries, such as Fiji, Tonga or Samoa, to continental territories, due to the rise in sea level caused by the melting of the poles due to global warming.
Another example may be the desertification of certain regions, which would encourage migration by the inhabitants of these places to other territories.
Finally, climate change and its negative effects not only generate massive migrations caused by natural effects, but also by the economic effects of said changes, that is, by increases in poverty and inequality in the face of the scarcity of certain natural resources.
