In the past 200 years, the earth's temperature has increased greatly. It's reported that a marked increase in the temperature of about 0.7℃ appeared at the end of last century. Some scientists think mini-umbrellas (微型伞) might reduce the global (全球的) temperature. Building a single ...

Before the Industrial Revolution of the 1800s, levels rose to about 280 parts per million. Today they are about 415 parts per million. The researchers announced plans to use their temperature calculation methods to recreate warm periods in Earth’s history. “If we can reconstruct past warm ...
At last, the ice began to melt (融化). After half a million years, most of it had melted. More than half of the earth became covered with water. The climate became much warmer. Things began to grow. The earth began to look the way it looks today. 【小题1】Millions of years ago ...
Snyder based her reconstruction on 61 different sea surface temperature proxies from across the globe, such as ratios between magnesium and calcium, species makeup and acidity. But the further the study goes back in time, especially after half a million years, the fewer of those proxies are ava...
