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.

Study: countries seeking to cut CO2 emissions must get a handle on city-level emissions

Green Car Congress

Prof Dabo Guan, professor of climate change economics at the University of East Anglia (UEA), led the research, along with Dr Yuli Shan from UEA’s School of International Development. Rather than creating low-carbon pathways at a national level, we need a pathway for each city. —Prof Guan.
