If the world’s climate is getting warmer, we should fi nd that some of the ice at both the North and the South Pole is melting at an unusually high rate. If the ice is melting, we should see its effect in the raising of the level of the sea. The world’s climate is getting warmer so we should fi nd evidence that the sea level is rising.
