by Bruce F. Molnia, Research Geologist 

• Although the oceans contain more than 95% of the Earth.s water, glaciers hold 75% of the fresh water
• If all the world's glaciers melted, sea level would rise more than 250 feet
• Of Alaska.s 2,000 or so large glaciers, more than 99% are now retreating or stagnating
• Photos taken decades apart at Glacier Bay reveal the dynamic evolution of the glacial landscape
• Why are Alaska's glaciers now contributing more water to raising sea level than Antarctica and other polar areas?
