The Montreal Protocol is working, but it will take several decades for ozone to return to 1980
levels. The atmospheric concentrations of ozone depleting substances are decreasing, and …

Anthropogenic increases in atmospheric greenhouse gas concentrations are the main driver
of current and future climate change. The integrated assessment community has quantified …

Solar ultraviolet-B (UV-B) radiation has played a crucial role in the evolution of life on Earth.
UV exposure presents both risks and benefits to humans. Optimal UV-B exposure behaviors …

This assessment by the Environmental Effects Assessment Panel (EEAP) of the United
Nations Environment Programme (UNEP) provides the latest scientific update since our …

The Montreal Protocol has limited increases in the UV-B (280–315 nm) radiation reaching
the Earth's surface as a result of depletion of stratospheric ozone. Nevertheless, the …

This report assesses the effects of stratospheric ozone depletion and anticipated ozone
recovery on the intensity of ultraviolet (UV) radiation at the Earth's surface. Interactions …

The control of the production of ozone-depleting substances through the Montreal Protocol
means that the stratospheric ozone layer is recovering and that consequent increases in …

The impact of stratospheric ozone on the tropospheric general circulation of the Southern
Hemisphere (SH) is examined with a set of chemistry‐climate models participating in the …

A continuous tropospheric and stratospheric vertically resolved ozone time series, from 1850
to 2099, has been generated to be used as forcing in global climate models that do not …

Short chain perfluoroalkylcarboxylic acids (scPFCAs, CxF2x+ 1COOH, x≤ 3) are persistent
compounds formed from atmospheric oxidation of fluorotelomer compounds and …
