Study estimates California’s GHG reductions since 2003 could be wiped out by 2020 wildfires

Green Car Congress

In an open-access report in the journal Environmental Pollution , researchers from UCLA and the University of Chicago estimate that California’s wildfire carbon dioxide equivalent (CO 2 e) emissions from 2020 (~127 mmt CO 2 e ) are approximately two times higher than California’s total greenhouse gas (GHG) emission reductions since 2003.

Met Office Climate Scientist: “Apocalyptic Predictions” Of Climate Change Can Impede Understanding Of Long-Term Warming Trends

Green Car Congress

News headlines vie for attention and it is easy for scientists to grab this attention by linking climate change to the latest extreme weather event or apocalyptic prediction. But in doing so, the public perception of climate change can be distorted. This message is more difficult to get heard. Vicky Pope, Met Office.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

New research led by the University of Washington (UW) is the first to measure this phenomenon’s effect over years and at a regional scale. The new study uses observations from 2003 to 2015 in spring, the cloudiest season, over the shipping route between Europe and South Africa. Michael Diamond/University of Washington.

Study of emissions from CNG- and gasoline-fueled autorickshaws suggests measurements and data, not assumptions, should drive policy

Green Car Congress

By 2003, all buses, taxis and auto-rickshaws in Delhi were retrofitted to run on CNG; only new vehicles with CNG engines are now available. (Of and THC, less CO than PET-4S) and climate benefits (lower fuel consumption, less GWC than CNG-2S). The mean fuel-based PM 2.5 emission factor (mean (95% confidence interval)) for CNG-2S (14.2
