Global warming infact DOES cause Tsunamis, along with earthquakes,volcano eruptions and others in unexpected places. When global warming heats up all the ice it melts and increases sea levels. Ice is very heavy and weighing about one tonne per cubic metre. Glaciers are huge sheets of ice, when they are in one peace they exert enormous pressure on the amount of earths surface they cover.
