Heat Pumps Take on Cold Climates

Cars That Think

Twenty homes scattered across Canada and the northern United States are keeping warm this winter using prototypes of the latest iteration in residential heating systems: cold climate heat pumps. To prove it, eight manufacturers are publicly testing their prototypes in the Cold-Climate Heat Pump Technology Challenge , hosted by the U.S.

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. —Solomon et al.

Field study finds soot particles absorb significantly less sunlight than predicted by models; climate models may be overestimating warming by BC

Green Car Congress

Although viewed as a potential target in the global effort to reduce climate change, atmospheric black carbon particles absorb significantly less sunlight than scientists have predicted, according to a new study by an international team of researchers, published in the journal Science. —Cappa et al.

New phase of globalization could undermine efforts to reduce CO2 emissions

Green Car Congress

A new study finds that the growth of carbon production from Chinese exports has slowed or reversed, reflecting a “new phase of globalization” between developing countries that could undermine international efforts to reduce emissions. The paper is published in Nature Communications. —Prof Guan.

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

Green Car Congress

The researchers set out a framework for gathering and analyzing local information about how cities contribute to pollution levels, and show how these insights could be used to target climate mitigation initiatives most effectively. Rather than creating low-carbon pathways at a national level, we need a pathway for each city.
