Stability of Ecosystem CO2 Flux in Response to Changes in Precipitation in a Semiarid Grassland

By Kaiqiang Bao et al. Abstract : Carbon dioxide (CO2) flux provides feedback between C cycling and the climatic system. There is considerable uncertainty regarding the direction and magnitude of the responses of this process to precipitation changes, hindering accurate prediction of C cycling in a changing world. We examined the responses of ecosystem CO2

A New Temperature Reconstruction From Central Asia Shows 432 Years Of No Warming, Recent Cooling

By Kenneth Richard Tree-ring evidence reveals recent cooling and glacier thickening in Central Asia as well as flat temperatures throughout the last 432 years.B Tree rings were the proxy used by Dr. Michael Mann to invent the orignal hockey stick graph. Twenty years later, yet another reconstruction (1580 to 2012 AD) indicates modern warmth in

Sunlight-Fueled, Low-Temperature Ru-Catalyzed Conversion of CO2 and H2 to CH4 with a High Photon-to-Methane Efficiency

By Francesc Sastre et al. Methane, which has a high energy storage density and is safely stored and transported in our existing infrastructure, can be produced through conversion of the undesired energy carrier H2 with CO2. Methane production with standard transition-metal catalysts requires high-temperature activation (300–500 °C). Alternatively, semiconductor metal oxide photocatalysts can be used,
