Arctic Sea Ice Melts to Its Lowest Level EverThe sea ice of the Arctic shrank to its lowest-ever level thisweek, shattering the previous...Michael McCarthy Environment Editor
If the high emissions continue, major ice shelves will collapse by 2070, according to the report, which also suggests sea level rise would accelerate to rates not seen in 20,000 years. Furthermore, ocean acidification and over-fishing will alter Southern Ocean ecosystems, and a failure to mana...

When floating ice melts in the lab, there is one secondary effect which very slightly affects water level: salinity. The mixing of fresh (or nearly fresh) meltwater with sea water reduces its salinity, which reduces its density. The effect is too small to see in my experiment (less than ...
What would happen if all the ice on Earth melted? How do glaciers and ice sheets change the Earth's crust? An ice cube floats in a glass of water. as the ice melts, what happens to the water level? Is Antarctica affected by global warming? How much has sea level risen since 1900?
scientists formerly thought that most of the loss came from “calving,” when warming temperatures causes glaciers or icebergs to split apart and sink into the sea. The discovery will help measure how ice loss contributes to sea level rise, as Antarctica contains 60 percent of the world’s fre...
And it could disappear if temperatures rise much more. Polar bears still suffer hunger.(冰川混合物在北极周围地区并不普遍。如果气温继续上升,它可能会消失。北极熊仍然在挨饿。)”可知,如果气温继续上升,冰川混合物也会消失,北极熊仍会挨饿,综合以上信息,气候变暖应是北极熊数量的减少的主要原因。故选D项。
