In 1995, the Intergovernmental Panel on Climate Change (IPCe) considered a global average temperature rise of 1.0-3.5°C likely by the year 2100, with 2.0°C its best estimate. Predict the average rise in sea level due to thermal expansion of sea water based on temperature rises of 1.0°C, 2.0°C, and 3.5°C given that the volume of the Earth's oceans is 1.37 x 109 km3 and their surface area is 361 X 106 km/, and state the approximations that go into the estimates.
