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 ...
