Significance We assessed the effects of air pollution and greenhouse gases on public health, climate, and the hydrologic cycle. We combined a global atmospheric chemistry–climate model with air pollution exposure functions, based on an unmatched large number of cohort studies in many countries. We find that fossil-fuel-related emissions account for about 65% of the excess mortality rate attributable to air pollution, and 70% of the climate cooling by anthropogenic aerosols. We conclude that to…

Climate and air-quality benefits of a realistic phase-out of fossil fuels
It is shown that more realistic modelling scenarios do not produce a substantial near-term increase in either the magnitude or the rate of warming, and in fact can lead to a decrease in warming rates within two decades of the start of the fossil-fuel phase-out.
Reducing Planetary Health Risks Through Short‐Lived Climate Forcer Mitigation
Global air pollution and climate change are major threats to planetary health. These threats are strongly linked through the short‐lived climate forcers (SLCFs); ozone (O3), aerosols, and methane
Global Burden of Disease from Major Air Pollution Sources (GBD MAPS): A Global Approach
Global anthropogenic emission inventories remain vital for understanding the sources of atmospheric pollution and the associated impacts on the environment, human health, and society. Rapid changes
Climate effects of aerosols reduce economic inequality
The climate effects of anthropogenic aerosols have masked some of the warming induced by GHGs 1 along with some impacts of that warming 2 . These temperature effects may be beneficial but are almost
Global Climate and Human Health Effects of the Gasoline and Diesel Vehicle Fleets
The global radiative forcing and human health impacts of the global gasoline and diesel sectors are quantified using the NCAR CESM global chemistry‐climate model for year 2015 emissions from the IIASA GAINS inventory to find substantial regional variability of premature death rates.
Climate and air quality impacts due to mitigation of non-methane near-term climate forcers
Abstract. It is important to understand how future environmental policies will impact both climate change and air pollution. Although targeting near-term climate forcers (NTCFs), defined here as
Air quality and health impact of future fossil fuel use for electricity generation and transport in Africa.
Sensitivity of the burden of disease to either population growth or air quality varies regionally and suggests that emission mitigation strategies would be most effective in Southern Africa, whereas population growth is the main driver everywhere else.
Paris Agreement's Ambiguity About Aerosols Drives Uncertain Health and Climate Outcomes
Anthropogenic aerosols are hazardous to human health but have helped offset warming from greenhouse gases (GHGs), creating a potential regulatory tradeoff. As countries implement their GHG reduction
A global anthropogenic emission inventory of atmospheric pollutants from sector- and fuel-specific sources (1970–2017): An application of the Community Emissions Data System (CEDS)
Abstract. Global anthropogenic emission inventories remain vital for understanding the sources of atmospheric pollution and the associated impacts on the environment, human health, and society. Rapid


Climate Impacts From a Removal of Anthropogenic Aerosol Emissions
Under near-term warming, it is found that regional climate change will depend strongly on the balance between aerosol and GHG forcing, and higher sensitivity of extreme events to aerosol reductions, per degree of surface warming, over the major aerosol emission regions.
Simultaneously Mitigating Near-Term Climate Change and Improving Human Health and Food Security
14 measures targeting methane and BC emissions that reduce projected global mean warming ~0.5°C by 2050 and increases annual crop yields by 30 to 135 million metric tons due to ozone reductions in 2030 and beyond are identified.
The effect of future ambient air pollution on human premature mortality to 2100 using output from the ACCMIP model ensemble.
Mortality estimates differ among chemistry-climate models due to differences in simulated pollutant concentrations, which is the greatest contributor to overall mortality uncertainty for most cases assessed here, supporting the use of model ensembles to characterize uncertainty.
An Estimate of the Global Burden of Anthropogenic Ozone and Fine Particulate Matter on Premature Human Mortality Using Atmospheric Modeling
The global burden of mortality due to O3 and PM2.5 from anthropogenic emissions is estimated using global atmospheric chemical transport model simulations of preindustrial and present-day (2000) concentrations to derive exposure estimates.
Radiative forcing and climate response to projected 21st century aerosol decreases
Abstract. It is widely expected that global emissions of atmospheric aerosols and their precursors will decrease strongly throughout the remainder of the 21st century, due to emission reduction
Irreversible climate change due to carbon dioxide emissions
The climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop, showing that thermal expansion of the warming ocean provides a conservative lower limit to irreversible global average sea level rise.
The contribution of outdoor air pollution sources to premature mortality on a global scale
It is found that emissions from residential energy use such as heating and cooking, prevalent in India and China, have the largest impact on premature mortality globally, being even more dominant if carbonaceous particles are assumed to be most toxic.

Disentangling the effects of CO2 and short-lived climate forcer mitigation
It is shown that the short- and long-term climate effects of many SLCF measures consistently become smaller in scenarios that keep warming to below 2 °C relative to preindustrial levels, reinforcing that SLCf measures are to be considered complementary rather than a substitute for early and stringent CO2 mitigation.
