7  Thermal expansion contributes major sea level increase, but not as much as adding freshwater  Glacial melt could contribute 130 – 160 mm increase  Antarctic ice cap melting offset by increased precipitation  Redistribution of Antarctic sea ice (melting) increases equatorial & northern sea level through gravity effect

8 Mammals 'floated to Madagascar' By Mark Kinver Science and environment reporter, BBC News The ancestors of the current mammals found on the island of Madagascar could have been transported on floating vegetation from Africa, a study says.
