According to a new study published in the journal Nature, the global ban of chlorofluorocarbons and other ozone-depleting substances prescribed by the 1987 Montreal Protocol and its subsequent amendments has prevented the eventual collapse of the ozone layer, thereby shielding vegetation from harmful ultraviolet radiation.

As areas across North America experience record-setting heat waves and face extended periods of drought, scientists at the National Center for Atmospheric Research (NCAR) are working to better understand and predict these extreme weather and climate events that impact human health and well-being.

Wildfire experts are available to discuss a range of topics, from wildfire prediction to the role of climate change and the impacts of emissions.

An international team of researchers has determined the chemical processes behind the formation of atmospheric formic acid, which will lead to improved weather and climate models.

Australian fires in 2019 and 2020 injected almost 1 million metric tons of smoke into the stratosphere, causing it to warm and likely contributing to a large and persistent ozone hole.
