Atmospheric aerosol particles (also known as particulate matter) are central to the cause of
the two greatest threats to human security: air pollution (~ 5 million premature deaths per …

Carbonyl sulphide (OCS) is found to be the predominant sulphur-bearing compound in our
atmosphere1–3. It contributes to the formation of stratospheric sulphate aerosol particles4 …

Protecting human health from fine particulate matter (PM) pollution is the ambitious goal of
clean air actions, but current control strategies largely ignore the role of source-specific PM …

About half of the anthropogenic CO2 emissions remain in the atmosphere and half are taken
up by the land and ocean. If the carbon uptake by land and ocean sinks becomes less …

Future climate warming is expected to enhance plant growth in temperate ecosystems and
to increase carbon sequestration,. But although severe regional heatwaves may become …

Ocean models predict a decline in the dissolved oxygen inventory of the global ocean of one
to seven per cent by the year 2100, caused by a combination of a warming-induced decline …

The potential for atmospheric aerosol particles to exist as metastable aqueous droplets
instead of in their thermodynamically favoured crystalline solid phase has many implications …

The push toward cleaner air in Beijing before the 2008 Olympic Games was a vivid reminder
of the need to control air pollution, not only in Asia but in many regions of the world. There is …

The most important chemical cleaning agent of the atmosphere is the hydroxyl radical,, OH.
It determines the oxidizing power of the atmosphere, and thereby controls the removal of …

AIRBORNE particulates have a major role in the air pollution problem. They are responsible
for acid rain, reduced visibility, and, in certain size ranges, are deposited in the lungs where …
