When snow or ice melt, they are replaced by darker melt-water pools, land or sea.
It's like when you put your summer drink together, as the ice melt doesn't change it because...
That raises the temperature of the sea, making the ice melt even faster.
For him, the video echoed his experiences in the Arctic, surveying bears that are struggling because of sea ice melt.
This confirms predictions of earlier computer models and demonstrates that rising temperatures will be affecting sea levels due to Arctic ice melt.
The researchers also included projections for sea level rise in Europe that includes the effects of thermal expansion, ice melt and storm surges.
BBC: 'Best estimate' for impact of melting ice on sea level rise
According to both groups of researchers, most areas of the world had higher than average temperatures in 2012 while the Arctic experienced a record breaking ice melt.
While ice melt is a major contributor to the height of the seas, there are other important factors especially thermal expansion caused by the warming of the waters.

The general warming trend -- 13 of the warmest years have occurred in the 15 years since 1997 -- was highlighted by summer sea ice melt in the Arctic.
The agency said worse case scenarios, including the contribution of polar ice melt and thermal expansion, could result in much higher levels occurring but these were now thought to be unlikely.
Taken together with the ice melt estimate, the scientists say the overall, maximum impact on the seas by 2100 will be a rise of 69cm - just 10cm higher than the IPCC projection in 2007, termed AR4.
BBC: 'Best estimate' for impact of melting ice on sea level rise
For the Arctic ice melt to make sense, all you have to do is watch this YouTube video, from the National Oceanic and Atmospheric Administration, which shows the puny extent of sea ice in 2012 compared with the historical average.
The Flood Protection Association said compacted snow and ice would melt more slowly than snow on the ground.
In Minnesota on Monday, people were watching the ice there melt, a steady rain helping the process, Tetrault said.
Nasa is coming under fire for an alarming headline in a news release warning: " Satellites see Unprecedented Greenland Ice Sheet Melt".
Heat and ice-melt could swell seas far more than originally predicted, and critically for the administration, this means mainland America would be hit too.
Is the ice-melt already beginning in March in the Arctic Circle?
NASA's scientists have designed a device that would be carefully sterilised, and would then melt its way down through the ice, allowing the melt-water to freeze behind it to prevent contamination.
Higher temperatures will melt ice, which lowers the albedo, reducing reflection of sunlight back out into space.
FORBES: Maybe Climate Change Just Really Isn't A Problem After All?
In 60 years the ice caps could melt and one fifth of the world's land will go under water.
This is that a warming atmosphere will melt ice at the poles.
Consequently, researchers don't yet know exactly how much of the ice-sheet melt is caused by a warming atmosphere and how much by a warming ocean.
This phenomenon, called Arctic amplification, occurs as highly reflective Arctic ice and snow melt away, allowing dark land and exposed ocean to absorb more sunlight.
CNN: Warmest Arctic temperatures for 2,000 years, says new study
This warming is causing glaciers and ice shelves to melt, releasing large volumes of fresh water into the oceans which not only raises sea level, but also influences regional climate change.
Scientists note that current climate-change models predict that some parts of the Antarctic ice sheet will grow while other parts will shrink, and that parts of the Greenland ice also will melt.
The owner can melt the ice in 24 hours to switch it to a basketball court.
By September the ice regularly used to melt to 7m square kilometres.
For we rather like being able to drive places, cook food, heat water and survive a Mid-West winter without having to melt the ice on the pitcher each morning.
FORBES: Bill McKibben's Latest Nonsense: Consumers Are The Climate Change Problem, Not Corporations
When the vast ice sheets and glaciers melt, they lose their reflective power, and instead, oceans and land absorb the heat, causing the Arctic waters and the atmosphere to warm faster.
CNN: Ice melting across globe at accelerating rate, NASA says
