Formation of soil organic matter via biochemical and physical pathways of litter mass loss
|
Soil organic matter is the largest terrestrial carbon pool (1). The pool size depends on the balance between formation of soil organic matter from decomposition... |

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... |

Significant anthropogenic-induced changes of climate classes since 1950
|
Anthropogenic forcings have contributed to global and regional warming in the last few decades and likely affected terrestrial precipitation. Here we examine ch... |

Uncertainty in the response of transpiration to CO2 and implications for climate change
|
While terrestrial precipitation is a societally highly relevant climate variable, there is little consensus among climate models about its projected 21st centur... |

The influence of contextual cues on the perceived status of consumption-reducing behavior
|
The question of whether and when behaviors that reduce overall consumption are associated with low status has not been adequately explored. Previous research su... |

Sustainable Development under Population Pressure: Lessons from Developed Land Consumption in the Conterminous U.S.
|
Population growth will result in a significant anthropogenic environmental change worldwide through increases in developed land (DL) consumption. DL consumption... |

Groundwater depletion and sustainability of irrigation in the US High Plains and Central Valley
|
Aquifer overexploitation could significantly impact crop production in the United States because 60% of irrigation relies on groundwater. Groundwater depletion ... |

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... |

Comment:Nuclear winter is a real and present danger
|
Models show that even a ‘small’ nuclear war would cause catastrophic climate change. Such findings must inform policy, says Alan Robock. |
|
Protected areas facilitate species’ range expansions
|
The benefits of protected areas (PAs) for biodiversity have been questioned in the context of climate change because PAs are static, whereas the distributions o... |
