A major impact of climate change is expected to be sea level rise (Sea-level Rise and Variability). Over the next century glacier melt will continue to be an major contributor to sea level rise along with thermal expansion of the ocean. Contributions from the ice sheets of Greenland and Antartica are rather uncertain but due to the large volume of grounded ice involved they are expected to be of great importance on the century timescale.
Glaciers respond in an integrated way to climate change and so evidence of glacier retreat around the world is a testament to the changing climate over the past century or so (BBC Rivers of Ice).
