Answer:
It is difficult to predict exactly how much global-mean sea level will increase by the end of the 21st century compared to pre-industrial times. However, according to the Intergovernmental Panel on Climate Change (IPCC), global-mean sea level is expected to rise by between 0.26 and 0.77 meters by the end of the century, with a best estimate of 0.55 meters. This estimate is based on the assumption that greenhouse gas emissions will continue to increase throughout the century, leading to further warming of the planet and consequent melting of land-based ice, such as glaciers and ice sheets. If emissions are reduced and global warming is limited, the projected rise in sea level may be less than this estimate. However, if emissions continue to increase and global warming accelerates, the rise in sea level could be even greater.
