Not Your Grandpa's RV: This Roving Lab Tracks Air Pollution Atmospheric scientist Ira Leifer installed special air sensors on a camper, then drove from Florida to California, measuring methane levels all along the way. More than 6,000 readings later, he found some noticeable spikes, especially around petrochemical plants and urban areas like Los Angeles. |

Go Fish (Somewhere Else): Warming Oceans Are Altering Catches Fish are moving away from the equator and toward the poles in order to maintain their preferred water temperature. That means, for example, that fishermen are seeing swordfish normally found in the Mediterranean swimming near Denmark. But in the tropics, there are no fish to replace the ones that are leaving. |

'Dangerous Territory': Carbon Dioxide Levels Reach Milestone The amount of carbon dioxide in the atmosphere has crossed the "psychological threshold" of 400 parts per million. That number is one of the clearest measures of how humans are changing the planet by burning fossil fuels. |

Can Acid Neutralizers Help Coral Reefs Bounce Back? Coral reefs are in trouble worldwide, from a host of threats, including warming ocean temperatures, nutrient runoff and increasing ocean acidity. A noted climate scientist from California has been conducting an experiment on Australia's Great Barrier Reef to see whether antacid could boost coral growth. |

Increased Carbon Dioxide Levels Damage Coral Reefs Scientists have been worried about coral reefs for years, since realizing that rising temperatures and rising ocean acidity are hard on organisms that build their skeletons from calcium carbonate. Researchers on Australia's Great Barrier Reef are conducting an experiment that demonstrates just how much corals could suffer in the coming decades. |

Could An 'Artificial Leaf' Fuel Your Car? Right now, solar panels make electricity. But a team of engineers in California wants to take solar energy one step further. They're trying to create a device that uses sunlight to make a liquid fuel that goes in our gas tanks. |

Energy Secretary Nominee Dodges Question On Gas Exports A U.S. Senate committee held a confirmation hearing for Ernest Moniz on Tuesday, who has been nominated to be the U.S. Energy Secretary. Moniz says he will retire from MIT, where he's a professor of physics and energy systems. He would advocate for the Obama administration's "all of the above" energy strategy, which calls for continued fossil fuels development and supports nuclear energy, wind and solar. |

This Scientist Aims High To Save The World's Coral Reefs Ken Caldeira is trying to come up with a big solution to the problem of increasingly acid oceans: antacids for coral reefs. That might keep the reefs from being destroyed by humans' use of fossil fuels. And that's not his only big idea. But even Caldeira admits that his audacious plan could fail. |

EPA Proposes New Rule To Clean Up Gasoline And Reduce Smog The Environmental Protection Agency (EPA) proposed on Friday a rule to clean up gasoline. The new lower sulfur gas is already what California uses to reduce air pollution, and the EPA wants it to be used nationwide. The agency estimates that it would save lives while adding a penny a gallon to the cost of gas. The oil industry fears it will cost more. |

Coal And Coral: Australia's Self-Destructive Paradox The city of Gladstone is the world's fourth largest coal-export hub. It's also a jumping off point to the southern end of the Great Barrier Reef. But coal mining could eventually kill the reef that Australians revere. |

Scientists Use Antacid To Help Measure The Rate Of Reef Growth There's some evidence that carbon dioxide we pump into the atmosphere has slowed the development of coral reefs. So researchers are adding antacid to the water in a tiny part of the Great Barrier Reef, to see whether the corals will grow faster if their water supply is less acidic. |

It's 'Birds Gone Wild' Out On Australia's Heron Island Normally, the buff-breasted rail is a shy little creature. But on this island out on the Great Barrier Reef, it's become the avian equivalent of a weed. And the island is dotted with other pesky and sometimes (to visitors) menacing birds. |
