Antarctic animals are at risk of being ‘sunburnt’ as the ozone hole opens for longer, scientists have warned, and climate change could be to blame. As if the impact of global heating on sea ice weren’t bad enough, penguins, seals and other wildlife are also being exposed to harmful ultraviolet (UV) radiation during their summer. Ozone gas forms a protective layer in the Earth’s upper stratosphere. The realisation that some chemicals - primarily chlorofluorocarbons (CFCs) used as refrigerants - were depleting it led to a major intervention in 1987: the Montreal Protocol. It is widely considered...

Air quality in Europe has improved over the last 20 years, according to new research. Despite this, most of Europe’s population still lives in areas that exceed the World Health Organization's (WHO) recommended levels. A team, led by the Barcelona Institute for Global Health (ISGlobal), estimated daily pollution levels in more than 1,400 regions across 35 European countries - an area with around 543 million people - between 2003 and 2019. Overall suspended particulate matter (PM2.5 and PM10) and nitrogen dioxide (NO2) levels have decreased in most parts of Europe over the last two decades. Fra...

Houston (AFP) - Extreme temperatures have combined with habitual smog in Houston for more than two weeks, and Erandi Trevino feels the hazardous combination in her body. "It burns my face. I feel it in my nostrils," Trevino says. The heat wave sprawling across the southern United States has lasted since June 14, and the sultry air and humidity make for temperatures that feel like they are higher than 40 degrees C (104 degrees F). Houston, the fourth most populous US city with 2.3 million people, is home to four oil refineries (one of them among the nation's largest), heavy industry, a tangle o...

Peotone (United States) (AFP) - After finding a rusty gas canister near his midwest US home, Rick Karas checked online if it was worth anything. Incredibly, it turned out to be a coveted commodity in the battle against climate change. His roughly basketball-sized container was filled with CFCs (chlorofluorocarbons), a potent greenhouse gas that is perfectly legal to possess but which has been globally banned from manufacture for decades. Absent a government mandate to destroy the ample existing stocks, a handful of companies have stepped in to hunt down the gases in a process funded by sellin...
