How much ice covered the Earth during the ice age? How much CO2 does a volcano emit? What caused the hole in the ozone layer over Antarctica? Is there a hole in the ozone layer above Australia? How much Arctic Sea ice has melted?
What is the coldest month in Antarctica? How thin is the ice in East Antarctica? Is Antarctica getting warmer? What are the seasons in Antarctica? What season is it in Antarctica in December? How much of Antarctica has melted? How is glacial melting affecting penguins in Antarctica?
第一题,To better understand how much and how fast seas could rise due to global warming, thirty-two scientists are starting a trip to a distant part of Antarctica, ( 1 ) the Thwaites glacier (冰川)is located.意为,为了更好地了解全球变暖可能导致海平面上升的幅度和速度,32名科学家正在开始南极...
Crevasses - one of the biggest and commonest hazards when travelling overland in Antarctica. These are cracks in the ice up to hundreds of feet deep that can be covered at the top by snow that blows over to form a weak bridge. Anyone passing through such terrain has to be vigilant, ...
Antarctica is freezing. Northern Canada in winter is freezing.南极洲是十分寒冷的。冬天的加拿大北部也是十分寒冷的。To see your breath means that you can literally see the air when you breathe on it.Usually if you can see your breath it is freezing.To see your breath 意思是当你呼吸的时候,你...
Modern, and still rising, CO2 levels may take us into some unsettling global terrain. During the last interglacial period, some 125,000 to 118,000 years ago, vast amounts of ice melted on Antarctica, resulting in awhopping six to nine meters of sea level rise. This happened gradually, ove...
That is worthy of attention because the Thwaites, along with the Pine Island Glacier and several smaller glaciers, acts as a brake on part of the much larger West Antarctic Ice Sheet, which , if melted, would raise the world's oceans by more than a meter over centuries, ...
The United States has a long history in Antarctica, starting with expeditions in the 19th century alongside many other nations at the time. Many geographic features in Antarctica are named after American explorers of the 19th and early 20th century who first sailed around it, then began to expl...
In the 11,400 years since the end of the lastIce Age, sea level has risen at an average of 4 feet/century, though it is now rising much more slowly because very nearly all of the land-based ice that is at low enough latitudes and altitudes to melt has long since gone." (...
When these icebergs melted, the resultant injection of cold freshwater was enough to drive down ocean temperatures by as much as 12掳C. These so-called Heinrich events are associated with rising atmospheric carbon dioxide (CO2) levels, but a mechanism to explain the connection convincingly has ...
