in addition the american meteorological society published a report entitled explaining extreme events of from a climate perspective that shows that humancaused climate change has influenced the frequency or intensity of events in a substantial manner the oceans store large amounts of heat which they redistribute around the planet sea water is heated by the sun in the tropics and then transferred by currents to temperate coasts where it cools down as it transfers its heat to the atmosphere colder and denser it sinks to a great depth where it moves back towards the equatorial regions and so on in a circuit lasting over a thousand years up until the sea level was measured by means of sealevel gauges positioned along continental and a number of island coasts the level of the oceans as a worldwide global average rose at the rate of mmyear between and and by some mmyear as from since measurements have been taken from satellites and have shown the mean annual sealevel rise to have been in the order of mmyear
