As the planet gets warmer, heating makes water expand and glaciers and ice sheets melt. That’s what makes sea levels rise.
A group of climate scientists are meeting this week in Copenhagen, Denmark to discuss the latest science surrounding the issue of climate change.
Scientists studying sea level rise are expected to announce at the Climate Change Congress that the projections in the 2007 IPCC report underestimated actual sea level rise. And, when the impact of melting ice sheets in Greenland and Antarctica is better understood more accurate sea level estimates can be made.
