The sudden melting of all ice would lead to a rise in global sea levels, submerging coastal cities and displacing millions of people.
Groundwater reserves would be contaminated, leading to a depletion of freshwater sources.
Marine life would be severely impacted, with many species facing extinction and others having to migrate to different habitats.
Climate changes would occur, including increased rainfall and the formation of rain clouds, resulting in floods and droughts in different regions.
The absence of glaciers would lead to an accumulation of carbon dioxide in the atmosphere, affecting air quality and making it harder to breathe.
