Presuming its question 8 is what u meant
During ice age type of the climate is harsh with extreme low temperatures and it is conducive for growth of flora and fauna. Most of the water is in frozen state
Coming to current scenario due to the global warming there has been a increase in earths temperature which resulted in the melting of glaciers(frozen water in the form of ice sheets in mountains ) .As a result of melting the sea level has been increasing gradually and consequently submerging the low lying coastal areas.
End result : land is shrinking and water level in oceans keeps on increasing. Its a menace to human life
