Rates of land ice melt continued to increase — providing a greater and greater fraction of overall global sea level rise.

A back of the envelope estimate of the addition of freshwater from land ice melting?

Mean sea level (MSL) evolution has a direct impact on coastal areas and is a crucial index of climate change since it reflects both the amount of heat added in the ocean and the mass loss due to land ice melt (e.g. IPCC, 2013; Dieng et al., 2017) Long - term and inter-annual variations of the sea level are observed at global and regional scales.

Most sea - level rise comes from water and ice moving from land into the ocean, but the melting of floating ice causes a small amount of sea - level rise, too.

Such erosion can result from any number of factors, including the simple inundation of the land by rising sea levels resulting from the melting of the polar ice caps.

In permafrost, ice holds up the soil; when the ice melts, the land surface slumps, creating features known as thermokarst failures.

If the melting of the polar ice caps injects great amounts of freshwater into the world's oceans, climate scientists fear that the influx could affect currents enough to drastically change the weather on land

Losing those shelves could presage the melting of their parent ice sheets on land — which could lead to a dramatic rise in sea level.

Warm currents can melt the floating ice shelves that hold back ice on land.

The latter destabilised Antarctic land ice, causing a continuation of melting that eventually drove sea level rise to several metres above the present,» he said.

Political divisions are less apparent with factual questions that do not infer climate change, such as whether the melting of Greenland and Antarctic land ice, or of Arctic sea ice, could potentially do the most to raise sea levels.

Starting next week, NASA's Operation IceBridge, an airborne survey of polar ice, will be carrying science flights over sea ice in the Arctic, to help validate satellite readings and provide insight into the impact of the summer melt season on land and sea ice.

In 1995, the ship featured as a rusty tanker in Kevin Costner's film Waterworld, captained by a deranged pirate bent on locating the last bit of land on a world where climate change has melted the ice caps.

The increase could be due to a combination of stronger winds spreading out the sea ice and fresh water from melting ice on land diluting seawater so it freezes at higher temperatures.
