June 16, 2021 Ozone is a pollutant at ground level, but very high in the atmosphere's 'ozone layer,' it absorbs damaging ultraviolet radiation. Past studies have examined ozone levels in the ...
May 8, 2023 New research provides clear evidence of a human 'fingerprint' on climate change and shows that specific signals from human activities have altered the temperature structure of Earth's ...
Dec. 7, 2020 Large amounts of new particles can form in the valleys of the Himalayas from naturally emitted gases and can be transported to high altitudes by the mountain winds and injected into the upper ...
Mar. 7, 2022 A new study challenges a commonly accepted explanation that a 'sudden stratospheric warming' caused the unusually cold weather over the U.S. early last year, a view which was widely ...
Sep. 27, 2023 Plastic waste that accumulates on land eventually ends up in the ocean as microplastics. However, it is now speculated that microplastics are also present in the atmosphere, contained in clouds. In a ...
May 12, 2021 The acidity of the atmosphere is increasingly determined by carbon dioxide and organic acids such as formic acid. The second of these impact the growth of clouds and pH of rainwater. But the chemical ...
Jan. 18, 2023 Scientists have shed new light on the 'self-cleaning' capacity of the ...
Apr. 22, 2022 New research has identified a lesser-known form of ozone playing a big role in heating the Southern Ocean -- one of Earth's main cooling ...
Sep. 9, 2021 The most devastating tornadoes are often preceded by a cloudy plume of ice and water vapor billowing above a severe thunderstorm. New research reveals the mechanism for these plumes could be tied to ...
May 19, 2022 Atmospheric researchers have discovered a mechanism that allows nuclei for ice clouds to form and rapidly grow in the upper troposphere. Although the conditions for nucleus formation are only ...
