Glaciers all across the world are melting at an alarming rate. Global warming is viewed as the chief culprit to melting glaciers. At the current rate of loss sea levels across the globe are expected to rise 7 meters by the end of this century. Low level land areas will literally be under the sea. Large numbers of population will have to be relocated to higher ground, placing greater demands on agriculture and land usage. The melting of glaciers will have an impact on our access to fresh water. Snow falls in glacier fields has already been diminished. The ability to expand glaciers has ceased to exist due to global warming. Some parts of the world, like in Iceland, will experience a short term benefit of increased hydro electric power due to increases in water flow from melting glacier fields. Short term benefits from melted glacier fields will provide a new opportunity for agriculture. Iceland for example is benefiting from a longer milder growing season, but existing shore lines are experiencing rising levels. The US is already seeking to build up sand dune areas in barrier islands due to rising ocean levels. Government reports do raise the possibility of having Florida and Manhattan under water as sea levels rise.
