Study finds that worldwide SO2 emissions rose between 2000-2005 after decade of decline; China, shipping topped growth

Green Car Congress

Global sulfur dioxide (SO 2 ) emissions peaked in the early 1970s and decreased until 2000, with an increase in recent years due to increased emissions in China, international shipping, and developing countries in general, according to a new analysis appearing in the open access journal Atmospheric Chemistry and Physics. —Smith et al.

Comprehensive assessment concludes black carbon second-most important human emission in warming climate

Green Car Congress

A comprehensive assessment of black-carbon climate forcing accepted for publication in the Journal of Geophysical Research: Atmospheres estimates that black carbon, with a total climate forcing of +1.1?W?m m -2 , is the second-most important human emission in terms of its climate-forcing in the present-day atmosphere.

Report Finds Rate of Growth of Global Greenhouse Gas Emissions Sharply Increased Between 2000 and 2005

Green Car Congress

Anthropogenic global greenhouse gas emissions increased by 15% between 2000 and 2005, a sharp increase in the expected rate of growth, according to a new report from the European Commission’s Joint Research Centre (JRC). At the same time, emission levels from industrialized countries have slowed down.

MIT report finds China’s actions on climate change crucial; argues for global economy-wide greenhouse gas tax

Green Car Congress

The report—titled “The Role of China in Mitigating Climate Change” and published in the journal Energy Economics , compares the impact of a stringent emissions reduction policy with and without China’s participation. From 2000 to 2010, China’s energy use grew 130%, up from a growth of 50% the previous decade.

Probability distribution for the committed warming by GHGs between 1750 and 2005. This would mean that the climate system is close to entering if not already within the zone of “dangerous anthropogenic interference” (DAI). They are poised to become a larger part of the climate problem over the next few decades. Earlier post.)
