Rising temperatures because of increased emissions of long-lived greenhouse gases (LLGHGs) have had and will continue to have significant negative impacts on crop yields. However, other climate changes caused by short-lived climate pollutants (SLCPs) are also significant for agricultural productivity. The SLCPs black carbon and ozone impact temperature, precipitation, radiation, and—in the case of ozone—are directly toxic to plants.

In this study the researchers developed improved global exposure estimates of ambient PM2.5 mass and trend using PM2.5 concentrations inferred from multiple satellites.

The use of reflective surfaces offers one low-cost solution for reducing solar loading to urban environments and the Earth that should be considered as part of sustainable urban design. Here, we characterize the radiative benefits, i.e. the additional shortwave radiation leaving the atmosphere, from the installation of highly reflective 'cool' roofs in urban areas in India that face relatively large local aerosol burdens.

Investigation of the chemical nature and sources of particulate matter at urban locations in four Chinese cities during a severe haze pollution event finds that the event was driven to a large extent by secondary aerosol formation.

Air pollution has had a significant impact on the amount of water flowing through many rivers in the northern hemisphere, according to the results of a new study.

Air pollution caused by humans and resulting in high concentration of aerosols in the atmosphere affected annual monsoon rainfall in the northern hemisphere.

This study deals with the effects of fireworks on the air quality over the major cities of India during the festival of light known as “Diwali”. The effects of firecrackers during the festival was assessed from the ambient concentrations of various air pollutants such as sulphur dioxide (SO2), nitrogen dioxide (NO2) and particulate matter (PM) with diameter less than 10 µm.

Phosphorus (P) is one of the most important limiting nutrients for the growth of oceanic phytoplankton and terrestrial ecosystems, which in turn contributes to CO2 sequestration. The solid-phase speciation of P will influence its solubility and hence its availability to such ecosystems.

The Amazon rainforest is responsible for absorbing tonnes of greenhouse gases from the atmosphere

Human conversion of forest ecosystems to agriculture is a major driver of global change. Conventionally, the impacts of the historical cropland expansion on Earth’s radiation balance have been quantified through two opposing effects: the release of stored carbon to the atmosphere as CO2 (warming) versus the increase in surface albedo (cooling).
