what do you mean "if"? It's happening.

If the Arctic ice cap melted then sea level would hardly be affected because the ice is floating and so it already displaces its own weight. If the Antarctic ice cap were to melt then a lot of land would be lost to the sea. We have lost thousands of square miles of land before. We used to be able to walk from the UK to Germany in the distant past. People could also walk from Australia to Tasmania or from Sarah Palin's home to Russia. However, to melt all of Antarctica is a huge task and will take a very long time. It won't happen any time soon even if it started now. See what NSIDC say about the lowest temperature on earth ever recorded (−134 to −137 degrees Fahrenheit): Not much ice melting there, I suspect.

If all the ice everywhere melted the sea level rise would be 65 meters (nowhere near a waterworld) but that would take hundreds of thousands of years, the amount of latent heat locked up in ice is truly enormous. However GPS monitored tide gauges are showing a yearly rise of 1.7mm (nothing to worry about) and some of that is due to us pumping out groundwater. There is also no reason to suppose sea levels will continue to rise, as our Earth has stopped warming (17yrs now with no rise in temperature) I worry much more about global cooling if that happens we are in big trouble.

Less ice / snow, less reflection of solar energy. More absorption of energy into the atmosphere, more ice melt. Greater and more damaging weather events. Global sea level rise. Human race is consuming itself. Seven billion and rising. There is a tipping point, and it's coming soon.

We as humans would be exploiting new land for agriculture.

The ice caps are melting and it is greatly inconveniencing the Inuit and the Polar bears. It is also affecting the weather in the lower states by slowing the Rossby waves in the jet stream, stalling weather patterns and making extreme weather more probable.

Sea levels would rise, coastlines would flood, over time
Answer #8 | 17/12 2013 20:12
This is happening as we speak, and it's worse than most people know. As the ice caps, melt it will kill off many arctic animals, flood our cities, and the cold water could even cause another ice age! These are long term affects, and if you just do your part to stay green, you won't have to worry about it! If you want to learn more, this wouldn't be the best place to do it, by the way! :) Do some research!

Then over thousands of years, the planet would get warmer, and the sea level would rise by many tens of meters.

In the short term, I think Greenland is the biggest cause for concern. As graphicconception states, it would take quite a long time to melt Antarctica and it requires a lot of energy. However Greenland is much closer to being at 0 C, and it may be possible for a substantial portion to melt or calve off in a relatively short time period. Although current sea level rise rates are relatively slow, there is no guarantee that they will stay that way, and it could be possible to have a sea level rise of a meter or more by the end of this century. The places that are most vulnerable are those coastlines with gentle gradients and a lot of land near (or even below) sea level. The Gulf Coast of the US, the Sacramento delta region and the Netherlands are examples of areas that would need to take additional protective measures or risk losing productive land to the ocean in strong storms.
