Receding Ice, Rising Oceans
|
| Topic: Climate |
11/20/09 |
| Astrobiology Magazine's climate blog, The Hot Zone, recently discussed how receding glaciers could have catastrophic consequences for Earth's climate. Increasing loss of glacial ice will lead to increasing water levels in the oceans. Ultimately, these changes could profoundly affect the biosphere. |

Measuring Climate Change
|
| Topic: Climate |
11/13/09 |
| Astrobiology Magazine's climate blog, The Hot Zone, recently spoke with Dr. Marty Mlynczak of NASA's Langley Research Center about the limitations of the technology we have on hand to measure climate change. Things we can't measure could be important in understanding the links between climate and habitability. |

Think Global, Act Local
|
| Topic: Climate |
11/06/09 |
| Recently, Astrobiology Magazine's climate blog, The Hot Zone, spoke with Dr. Anastasia Romanou, Associate Research Scientist at NASA GISS, about the need for precise local measurements of climate phenomena. Local measurements can provide information about the real impacts of climate change. |

A New Wrinkle in Ancient Ocean Chemistry
|
| Topic: Climate |
11/01/09 |
| Scientists widely accept that the Earth's atmosphere underwent a dramatic rise in oxygen 2.4 billion years ago, which ultimately paved the way for complex life on our planet. New research has helped solve some important questions surrounding this 'Great Oxidation Event'. |

Ocean Acidifcation, Climate's Step Sister
|
| Topic: Climate |
10/23/09 |
| The Hot Zone recently discussed ocean acidification and what it could mean for the future climate of Earth. Earlier this month expert panels organized by the United Nations discussed ocean acidification and the future of Earth's marine ecosystems. |

Stratosphere Cycles with the Sun
|
| Topic: Climate |
09/05/09 |
| Scientists have found that the 11-year solar cycle, the stratosphere and the tropical Pacific Ocean work in sync to generate periodic weather patterns that affect the globe. The findings could be used to predict future climate patterns on Earth. |

The Case of the Missing Ice
|
| Topic: Climate |
08/28/09 |
| By modeling ice sheets in Antarctica, scientists have changed the way we think about Earth's transition 34 million years ago from warm 'greenhouse' to the current, cool 'icehouse'. The new study has important implications for how we understand climate change and its affects on the biosphere. |

Ice Ages Follow the Sun
|
| Topic: Climate |
08/26/09 |
| Scientists have shed new light on the processes behind the Ice Ages experienced by Earth over the past 2.5 million years. Research indicates that they are ultimately linked to shifts in solar radiation caused by changes in the Earth's rotation and axis. |
