One says that the temperatures were so low that it never rained, but only 4.The last Ice Age on the Earth occurred not too far from today. Called "The Great Ice Age", it 5about 11,000 years ago. Over 1/3 of the Earth's land was buried in ice. Then, about 10,000 years ago,...
Scientists have calculated temperatures on Earth's surface during the last Ice Age. The researchers made their calculations with the help of fossilized remains of ocean plankton and models of climates tens of thousands of years ago in different parts of the world. The researchers reported their fin...
The Last Ice Age: Low Seas, Exposed Landmasses During an ice age, sea levels fall as ocean water that evaporates is stored on land on a large scale (ice sheets, ice caps, glaciers) instead ofreturning to the ocean. Earth's Ice Cover20,000 Years AgoToday ...
Earth has been experiencing a trend of cooling for about the past 50 million years. About 4.5 million years ago, the Isthmus of Panama land bridge formed between North America and South America, which may have triggered the last ice age. The Atlantic and Pacific oceans could no longer exchang...

Since the last ice age, humans have cleared nearly half of the earth’s forests and grasslands for agriculture. With the world population expanding, there’s ever-increasing pressure on farmland to produce not only more food but also clean energy. In places such as Yakima County, Washington, ...
Scientists are now finding mutual relations between models of solar-weather interactions and the actual climate over many thousands of years, including the last Ice Age. The problem is that the models are predicting that the world should be entering a new Ice Age and it is not. 科学家们现在...
M:Well,my notes say you earned $50,000 in profits last year,an extraordinary amount for a 20-year-oldstudent.Howdid that happen?Did you see a gap in the market and decide to fill it?嗯,我的笔记说你去年赚了5万美元的利润,对于一个20岁的学生来说,这是一个非常大的数字。那是怎么发生的...
Neanderthals, with whom we shared the planet until just before the last glacial maximum, 20,000 years ago,may have struggled to survive as the rising and falling ice ate away at their habitat– although many other explanations for their extinction have been suggested. What is beyond doubt is ...
