63703368 For the first time a map of the movement of Antarctic ice
Scientists first made a complete map of the displacement of ice in Antarctica. View the resulting animated clip can be here, and a brief description of the research is contained in a news release NASA. To map the experts used data collected in polar orbit satellites. Since in the hands of the researchers were photos of the same regions, taken at different times and from different angles, scientists were able to remove from the final picture of confounding factors – clouds, sun glare, "inconvenient" and other topographic features. It turned out that some ice packs are moving at speeds up to 244 meters per year, slipping on the ground under them. Thus can move very large pieces of ice, and this fact indicates the need for revision of many existing models that predict climate change. In the case of melting from the increase in water temperature ice packs that are on the coast, continental ice will be much easier to slide into the water, without encountering any obstacles in its path, the authors note. Recently, another research team has changed its forecast of global warming for the worse. The researchers analyzed the rate of disappearance of glaciers in the light of several climate models and concluded that terrestrial glaciers could melt much faster than predicted by most current theories.
