Study suggests future climate changes to worsen air quality for >85% of China’s population; ~20k+ additional deaths each year

Green Car Congress

A study by a team of researchers from China, the US and Germany suggests that future climate change may worsen air quality for more than 85% of China’s population, leading to an additional 20,000 deaths each year. Managing air quality in China in a changing climate will thus become more challenging. RCP 4.5). (The

Red colors represent a temperature increase, blue indicates a decrease, and beige indicates no change. In their paper, the authors note that several cautions must be taken in analyzing long-term climatic data in order to avoid misleading or erroneous conclusions. Mean annual temperature is changing throughout Alaska. 2009, 1949?

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 dashed line represents the aggregated CO2 emissions calculated from the provincial energy statistics 1997–2010.

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

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.
