To achieve the aspirational goal of the Paris Agreement on climate change—limiting the increase in global average surface temperature to 1.5 degrees Celsius above preindustrial levels—will require its 196 signatories to dramatically reduce their greenhouse gas (GHG) emissions. Those greenhouse gases differ widely in their global warming potential (GWP), or ability to absorb radiative energy and thereby warm the Earth's surface ..read more

Direct and indirect consumption activities drive urban-rural inequalities in air pollution-related mortality in China
Phys.org » Earth News
by
5h ago
Household consumption in China is associated with substantial PM2.5 pollution through activities directly (i.e., fuel use) and/or indirectly (i.e., consumption of goods and services) causing pollutant emissions. Urban and rural households exhibit different consumption preferences and living areas; thus, their contributions to and suffering from air pollution could differ ..read more

by
6h ago
In research published in the journal Science experts addressed setting standards for three key indoor pollutants—carbon dioxide (CO2), carbon monoxide (CO), PM2.5, which are particles so small they can lodge deep in the lungs and enter the bloodstream—and ventilation rate. The paper is titled "Mandating indoor air quality standards for public ..read more
