Flaring practices allow more methane into the atmosphere than thought; simple fixes can have big impact

Green Car Congress

Burning methane by flaring as it is released converts it to carbon dioxide, another greenhouse gas but one that is less harmful on a pound-by-pound basis. The new data suggests we have overestimated flaring’s effectiveness and, as a result, underestimated its contribution to methane emissions and climate change. Kort, Adam R.

Study Finds Stratospheric Water Vapor Is An Important Driver of Decadal Global Surface Climate Change

Green Car Congress

Earlier observations from satellites and balloons suggest that stratospheric water vapor probably increased between 1980 and 2000, which would have enhanced the decadal rate of surface warming during the 1990s by about 30% compared to estimates ignoring this change, according to the authors. —Solomon et al.

Canada and California to work together on cleaner transportation

Green Car Congress

Canada’s Minister of Environment and Climate Change, Catherine McKenna, and the Chair of the California Air Resources Board, Mary Nichols, today signed a new cooperation agreement to advance cleaner vehicles and fuels. Canada is developing a Clean Fuel Standard that will cut emissions by 30 million tonnes in 2030.

US and Swiss researchers model two very high carbon emissions scenarios

Green Car Congress

US and Swiss researchers have modeled two climate scenarios with very high carbon emissions—above the A1F1 scenario, currently representing the upper bound of predicted carbon emissions in the IPCC work—to investigate the resulting climate change implications. —Sanderson et al.

Study finds advanced cellulosic biofuels show real promise for replacing some fossil fuels

Green Car Congress

A new study led by Colorado State University predicts significant climate benefits stemming from the use of advanced biofuel technologies. These results affirm the climate mitigation logic of biofuels, consistent with their prominent role in many climate stabilization scenarios. —Field et al. —John Field.

NOAA study: Increase in stratospheric aerosols has offset some recent climate warming

The team concluded that models miss an important cooling factor if they don’t account for the influence of stratospheric aerosol, or don’t include recent changes in stratospheric aerosol levels.
