The chemicals in question, known as hydrochlorofluorocarbons (HCFCs), replaced the ozone-destroying chlorofluorocarbons (CFCs) once […]

Ozone hole closure not so cool

Using a new global aerosol model and two decades of meteorological data, University of Leeds climatologists have discovered a feedback effect related to the ozone hole’s closure that could actually increase warming in the southern hemisphere. The hole in the ozone layer above the Antarctic was once regarded as one of the biggest environmental threats, […]

Climatologists Mull Side-Effects Of Ozone Hole Closure

Climatologists modeling possible weather patterns that may occur when the ozone hole closes – projected to be sometime in the second half of the 21st century – say that its closure may significantly affect the climate in the Southern Hemisphere, with flow-on effects that will be felt all over the planet. Thanks to the Montreal […]
