But you don't mention this Of course not. The surface was the topic of discussion. You know, sea level. Where sea ice occurs. But even at depth, less energy is required to freeze fresh(ish) water than full salt sea water. And there is still a temperature differential. at the same time it is a fact, that the ice sheet grows in height, getting thicker all the time No Taro, that isn't a fact. At one time it was believed to be the case, but recent satellites have proven it just isn't true. Antarctica is shedding 160 billion tonnes a year of ice into the ocean, twice the amount of a few years ago, according to new satellite observations. The ice loss is adding to the rising sea levels driven by climate change and even east Antarctica is now losing ice. The new revelations follows the announcement last week that the collapse of the western Antarctica ice sheet has already begun and is unstoppable, although it may take many centuries to complete. Global warming is pushing up sea level by melting the world’s major ice caps and by warming and expanding oceans waters. The loss of the entire western Antarctica ice sheet would eventually cause up to 4 metres (13ft) of sea-level rise, devastating low-lying and coastal areas around the world. The new data, published in journal Geophysical Research Letters, comes from the European Space Agency’s CryoSat-2 satellite, which was launched in 2010. theguardian.com You need to keep up.
