After the talks
|
The real business of decarbonization begins after an agreement is signed at the Paris climate conference, argue David G. Victor and James P. Leape. |

rainfall preceded by air passage over forests
|
Vegetation affects precipitation patterns by mediating moisture, energy and trace-gas fluxes between the surface and atmosphere1. When forests are replaced by p... |

The Greening of Synfuels
|
An old, dirty technology to make transportation fuels from coal could
fight global warming, say proponents. The trick is using more biomass
and burying the ca... |

The Three Horsemen of Riches: Plague, War, and Urbanization in Early Modern Europe
|
How did Europe escape the “Iron Law of Wages?” We construct a simple Malthusian model with two sectors and multiple steady states, and use it to explain why... |

Multidecadal to multicentury scale collapses of Northern Hemisphere monsoons over the past millennium
|
Late Holocene climate in western North America was punctuated by periods of extended aridity called megadroughts. These droughts have been linked to cool easter... |

Rapid deposition of oxidized biogenic compounds to a temperate forest
|
We report fluxes and dry deposition velocities for 16 atmospheric compounds above a southeastern United States forest, including: hydrogen peroxide (H2O2), nitr... |

Changes in Avian and Plant Communities of Aspen Woodlands over 12 Years after Livestock Removal in the Northwestern Great Basin
|
Riparian and quaking aspen (Populus tremuloides) woodlands are centers of avian abundance and diversity in the western United States, but they have been affecte... |

The Disappearing Cryosphere: Impacts and Ecosystem Responses to Rapid Cryosphere Loss
|
The cryosphere—the portion of the Earth’s surface where water is in solid form for at least one month of the year—has been shrinking in response to climat... |

Comment: The end of cheap coal
|
New forecasts suggest that coal reserves will run out faster than many believe. Energy policies relying on cheap coal have no future, say Richard Heinberg and D... |

Sagebrush carrying out hydraulic lift enhances surface soil nitrogen cycling and nitrogen uptake into inflorescences
|
Plant roots serve as conduits for water flow not only from soil to leaves but also from wetter to drier soil. This hydraulic redistribution through root systems... |

Gas production in the Barnett Shale obeys a simple scaling theory
|
Natural gas from tight shale formations will provide the United States with a major source of energy over the next several decades. Estimates of gas production ... |

Soil warming, carbon–nitrogen interactions, and forest carbon budgets
|
Soil warming has the potential to alter both soil and plant processes that affect carbon storage in forest ecosystems. We have quantified these effects in a lar... |

How the type of anthropogenic change alters the consequences of ecological traps
|
Understanding altered ecological and evolutionary dynamics in novel environments is vital for predicting species responses to rapid environmental change. One fu... |

Fluvial landscapes of the Harappan civilization
|
The collapse of the Bronze Age Harappan, one of the earliest urban civilizations, remains an enigma. Urbanism flourished in the western region of the Indo-Gange... |

Effects of grazing on grassland soil carbon: a global review
|
Soils of grasslands represent a large potential reservoir for storing CO2, but this potential likely depends on how grasslands are managed for large mammal graz... |
