The Atlantic and Pacific Climate Connection
|
| Topic: Climate |
08/30/10 |
| Summary: Researchers are discovering new ways in which the Earth's oceans have influenced global climate. At the end of the last ice age, north Atlantic ice sheets melted, added fresh water and caused the collapse of the Atlantic Ocean conveyor belt. That should have plunged the northern Hemisphere into a deep freeze... but it didn't. |

| Summary: If we could make one change to stave off climate change, what would it be? One scientist believes that getting rid of black soot is the answer. Other research shows that fighting climate change with geo-engineering tricks, such as pumping out aerosols to reflect sunlight, may not be a solution. |

A History of Climate Change
|
| Topic: Climate |
06/21/10 |
| Summary: How did the Earth stay warm 3.8 billion years ago when the young sun was 30% weaker? It's a mystery scientists have long been trying to solve, and it may come down to global warming. Ancient warming on Earth can also provide important clues concerning modern climate change. |
