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

Green Car Congress

A new report from the MIT Joint Program on the Science and Policy of Global Change shows the importance of all major nations taking part in global efforts to reduce emissions—and in particular, finds China’s role to be crucial. The change, taken by China alone, would only reduce global temperature by about 0.1 2012.04.007.

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.

Copenhagen Diagnosis Released, Detailing Accelerating Indicators of Climate Change In Last Three Years

Green Car Congress

A team of 26 climate scientists from Australia, Austria, Canada, France, Germany, Switzerland, the United Kingdom, and the United States have published the “Copenhagen Diagnosis”, an interim synthesis report on developments in climate change science from mid-2006 to the present day.

New modeling study finds thawing permafrost could release vast amounts of carbon and accelerate climate change by the end of this century

Green Car Congress

Billions of tons of carbon trapped in high-latitude permafrost may be released into the atmosphere by the end of this century as the Earth’s climate changes, further accelerating global warming, a new computer modeling study indicates. The control simulation on the left did not include permafrost processes.

Survey finds public support for geoengineering research; strongest opposition from conservatives

Green Car Congress

Eight percent of the sample were able to provide a correct definition of geoengineering, an increase on previous estimates; however, 45% of the sample correctly defined the alternative term “climate engineering”, adding weight to the argument that “geoengineering” may be misleading and difficult to understand.

EEA: Higher EU greenhouse gas emissions in 2010 due to economic recovery and cold winter

Green Car Congress

Among the greenhouse gases reported to the United Nations Framework Convention for Climate Change (UNFCCC), carbon dioxide (CO 2 ) accounted for the largest increase in emissions in 2010. Germany, Poland and the United Kingdom accounted for 56% of the EU’s total net increase in GHG emissions.

EEA says industrial air pollution cost Europe up to €169 billion in 2009; some 37% attributed to CO2

Green Car Congress

Estimating the magnitude of costs associated with future climate change impacts is very uncertain. The approach used in this report, based on marginal abatement cost, is based on the existing approach used for public policy appraisal in the United Kingdom.
