How Earth´s Orbital Shift Shaped the Sahara
|
| Topic: Earth |
12/20/10 |
| A change in the Earth´s orbit, many scientists believe, transformed the "Green Sahara" into what is now the largest desert on the planet. While scientists are still trying to find out if the slow shift in orbit had rapid or gradual environmental consequences, they say Earth´s orbit will continue to change today and into the future. |

Thawing a Planet-Sized Snowball
|
| Topic: Earth |
11/04/10 |
| The Earth has plunged into a deep freeze several times in the past, with ice covering the land and sea for millions of years. Researchers are studying how the planet eventually escaped these cold spells, and whether Earth-like planets elsewhere in the galaxy may be susceptible to the same climate catastrophe. |

A Dark and Warm Early Earth
|
| Topic: Earth |
04/11/10 |
| Four billion years ago, the Sun radiated less energy than it does today. Scientists once believed that greenhouse gases must have helped the Earth stay warm during this time. However, new research shows that the large oceans may have simply absorbed more heat. |
