Just a slight rise to water temperature can shrink the base of icebergs by 5 meters to 2 kilometers every year, yet it is not visible from the surface. They also found that such phenomenon doesn’t need a dramatic increase in ocean water. The changes mean that very soon the sea-level contribution from Antarctica could outstrip that from Greenland,” said Professor Andrew Shepherd, one of the researchers contributing to the research. We can’t see it, because it’s happening below the sea surface. What’s happening is that Antarctica is being melted away at its base. However, after those researchers measured the iceberg underwater melt, the surprising number came up. The images of Antarctic icebergs have never showed dramatic changes like the ones in the Arctic area from the top. All this time, we have ignored the melting of south pole icebergs since it has always appeared relatively stable when viewed from satellite images. This discovery is a huge news for climate researchers and other people all around the world. That’s why they said that we need to revise our view toward the case.
The researchers from UK Centre for Polar Observation and Modelling at the University of Leeds stated that it might be the answer for unpredictable global sea rise happens nowadays. In the paper, the researchers also suggested that the rate tends to double every 20 years, meaning that in the next few years it is possible for the rate reach 400 square kilometers per year. That is the size of Greater London we are talking about, and the progression is severe enough to reach more than 200 square kilometers per year. Researchers, in a study published in Nature Geoscience estimated that the underwater dissolvement has caused the icebergs in south pole to shrink by 1,463 square kilometers in just 6 years. Warmer water temperature dissolves the base of icebergs floating in it slowly, but sure faster than how the atmosphere does to the top. Yes, the temperature of our ocean is also rising pretty significantly compared to decades ago. The biggest surface on earth, the ocean, is also affected by it. Indeed, global warming has caused the raise of average air temperature all around the world, thus no wonder the air temperature in the coldest places on earth does too.īut our atmosphere is not the only part of the planet affected by global warming. Warm Waterįor long we have believed that the melting of icebergs in both Antarctica and Arctic happens because of the raise of air temperature in both poles. How can this happen, and how can most people in this world just miss it right in front of their eyes? We will talk about it in this article. And this happens in an alarming rate that it is predicted to become the greatest source of the raise of sea level in the world. The fact is, underwater melt of icebergs is far greater than the melting in the surface that we are already aware of.
There is something far greater that is missing from public attention. However, that’s not the whole truth about melting icebergs. For a long time, common people believe that the melting of icebergs can be measured by visible cracks and running glaciers.
