The literature on atmospheric particulate matter (PM), or atmospheric aerosol, has increased
enormously over the last 2 decades and amounts now to some 1500–2000 papers per year …

This planetary boundaries framework update finds that six of the nine boundaries are
transgressed, suggesting that Earth is now well outside of the safe operating space for …

The Sahel experienced a severe drought during the 1970s and 1980s after wet periods in
the 1950s and 1960s. Although rainfall partially recovered since the 1990s, the drought had …

Freshwater blooms of phytoplankton affect public health and ecosystem services globally,.
Harmful effects of such blooms occur when the intensity of a bloom is too high, or when toxin …

We explore the role of agriculture in destabilizing the Earth system at the planetary scale,
through examining nine planetary boundaries, or “safe limits”: land-system change …

Poor air quality is currently responsible for large impacts on human health across the world.
In addition, the air pollutants ozone (O3) and particulate matter less than 2.5 µm in diameter …

Anthropogenic aerosols exert a cooling influence that offsets part of the greenhouse gas
warming. Due to their short tropospheric lifetime of only several days, the aerosol forcing …

Background: More than a decade of satellite observations offers global information about the
trend and magnitude of human exposure to fine particulate matter (PM2. 5). Objective: In this …

Airborne mineral dust particles can act as natural seeds for cirrus clouds in the upper
troposphere. However, the atmospheric abundance of dust is unconstrained in cirrus …

Aerosols from biomass burning (BB) emissions are poorly constrained in global and
regional models, resulting in a high level of uncertainty in understanding their impacts. In …
