Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

The report’s best estimate of direct climate influence by black carbon is about a factor of two higher than most previous work. This includes the estimates in the 2007 Intergovernmental Panel on Climate Change (IPCC) Assessment, which were based on the best available evidence and analysis at that time. Bond et al.

New phase of globalization could undermine efforts to reduce CO2 emissions

Green Car Congress

The study, involving researchers from the University of East Anglia (UEA) and colleagues in China and the United States, investigated how complex supply chains are distributing energy-intensive industries and their CO 2 emissions throughout the global South. The paper is published in Nature Communications. —Prof Guan. Coffman, D.’.

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. However, we cannot exclude.

Technical brief: transportation overtaking electricity generation as the largest source of US CO2 emissions

Green Car Congress

A technical brief by Dr. John DeCicco at the University of Michigan Energy Institute shows that transportation is overtaking electricity generation as the largest source of US CO 2. per year over 2007-2015 due to the displacement of coal by natural gas, wind and solar for power production as well as energy efficiency gains.

a five-spot well configuration was drilled in the summer of 2007 consisting of a center injection well surrounded by four monitoring wells. In addition to evaluating the lignite seam’s CO2 storage potential, the enhancement to coalbed methane extraction will also be evaluated. In collaboration with Eagle Operating Inc.,
