L'impact du changement climatique sur les pays du Maghreb[The impact of climate change on Maghreb countries]

A global climate change is a change in the climate of the entire planet. Climate change can occur naturally (ice age) so Earth's natural climate has always changed and will continue to change. Today, climate change differs from previous changes in its speed and magnitude because the greenhouse effect is a phenomenon that will affect the Earth's temperature. Greenhouse gases, especially water vapour, carbon dioxide, methane and nitrous oxide, trap the sun's heat, preventing the radiation from dissipating into space, however without these natural gases, Earth's average temperature would be -18°C. In this work, we will see what are the consequences of these climate changes on the economies of the Maghreb (Algeria, Morocco and Tunisia), in a global context. As well as the efforts to circumvent them.
