I've heard that the ice caps are melting. Is it true that sea levels are rising?

Yes, it is true that sea levels are rising. In fact, they have been rising steadily since the end of the last Ice Age, about 10,000 years ago. Scientists believe that this rise in sea level is due to the thermal expansion of ocean water as it warms up, and also due to the melting of land-based ice sheets and glaciers.
