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.

New Bayesian Approach Addressing Shared Biases Across Models Suggests That Stabilizing CO2 Concentrations at Current Levels Leaves 10% Chance of Exceeding 2C Target

Green Car Congress

Under benchmark risk management metrics, allowable emission paths should have less than a 10% chance of overshooting the target, Lemoine notes in a new paper published in the American Meteorological Society’s Journal of Climate , so policymakers “ may therefore require significant near-term abatement and eventual net negative emissions.

Study finds 1.4 Gt discrepancy between national and provincial data sets for greenhouse gas emissions in China

Green Car Congress

The gap, noted the researchers in their open-access paper in Nature Climate Change , is equivalent to Japan’s annual CO 2 emissions, the world’s fourth largest emitter, with 5% of the global total. The area chart shows the increase of CO 2 emissions calculated from the national energy statistics since 1997 broken down by different fuel type.

GCP Carbon Budget Finds Anthropogenic CO2 Emissions Rose 2% in 2008 Despite Global Financial Crisis; Natural Sinks Not Keeping Pace With Increasing Emissions

Green Car Congress

Using a variety of data including direct observations, computer-generated models, and estimates from countries’ energy statistics, the team created a global CO 2 budget—the amount of CO 2 produced and consumed—from 1959 to 2008.
