Effect of global warming on Earth's crust. Computer illustration showing how global warming affects the movement of the Earth's crust. Global warming melts the ice shelf, causing sea levels rise, which puts more pressure on the crust under the oceans (left). At the same time the reduction in the ice shelf reduces the pressure on the crust on land (centre). The combined effect of this lifts the crust on land, leading to increased volcanic activity (right).
