Study using paleoclimate data suggests climate sensitivity to CO2 doubling may be less severe than projected

Green Car Congress

The team combined extensive sea and land surface temperature reconstructions from the Last Glacial Maximum (LGM) with a climate model of intermediate. complexity to estimate the equilibrium climate sensitivity for a doubling of atmospheric carbon dioxide concentrations (ECS 2xC ) from. preindustrial times. preindustrial times.

Study finds global rivers and streams emitting 3x IPCC estimates of the GHG N2O

Green Car Congress

That’s three times the amount estimated by the Intergovernmental Panel on Climate Change (IPCC). This new global emission estimate is startling. Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction.

Study concludes climate models are not accurately reflecting soil carbon release

Green Car Congress

The study was published in the journal Biogeosciences by scientists from the College of Forestry at Oregon State University, the US Geological Survey, and the National Ecological Observatory Network. This feedback loop is one of our biggest worries with global warming, simply because the amount of carbon stored in soil is so huge.

Study Finds Unexpected Decadal Decline in Global Evapotranspiration, Links It to Moisture Limitation in Southern Hemisphere

Green Car Congress

The soils in large areas of the Southern Hemisphere, including major portions of Australia, Africa and South America, have been drying up in the past decade, according to the first major study of evapotranspiration on a global basis. This is the first time we’ve ever been able to compile observations such as this for a global analysis.

Researchers contend that large-scale forest bioenergy is neither sustainable nor greenhouse-gas neutral

Green Car Congress

Large-scale bioenergy production from forest biomass is unsustainable and will increase greenhouse gas emissions, according to a group of international researchers in an invited analysis in the journal Global Change Biology/Bioenergy. The work was supported by several agencies in Europe and the US Department of Energy. —Schulze et al.
