of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. The study was published in the journal Atmospheric Environment. Seen together, the climate impact of these two factors is bigger than that of the sector’s carbon emissions.

Study finds global carbon emissions reached 10 billion tonnes in 2010

Green Car Congress

Global carbon dioxide emissions from burning fossil fuels have increased by 49% in the last two decades, according to the latest figures from the Global Carbon Project. Published in the journal Nature Climate Change , the new analysis shows fossil fuel emissions increased by 5.9% Canadell and Michael R.

Black carbon (BC) is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this pollutant’s climate impact.

TOAR shows present-day global ozone distribution and trends relevant to health; public database

Green Car Congress

Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. The international scientists who compiled and analyzed the global ozone pollution database hope it will give scientists and public health managers better insight on trends and patterns of human health exposure around the world.

Study concludes abundant shale gas is neither climate hero nor villain; need for targeted GHG reduction policy

Green Car Congress

Shale gas in particular has grown rapidly, from less than one percent of US production in 2000 to 34% in 2012, and projections show strong production growth continuing for the foreseeable future. In this paper, we focus on the implications of growing shale gas production for the climate. —Newell and Raimi.
