What would happen if the temperature in the world rose enough to melt all the snow and ice at the North and South Poles?
No one knows for sure what would happen if the snow and ice in the polar regions all melted. Sea level would rise, which would flood coastal regions. Climate would be affected worldwide. Isostatic rebound would occur where ice masses were removed from continents, causing the land surface there to rise. Many scientists are trying to predict the effects of climate changes such as a general warming trend by using computer climate models. Much more research needs to be done before we can confidently predict results.
