According to a Canadian researcher, an ozone hole seven times bigger than the Antarctic ozone hole has been present across tropical regions since the 1980s. Qing-Bin Lu, a scientist from the University of Waterloo in Ontario, Canada, discovered a large, all-season hole — defined as an area of ozone lossContinue Reading
Researchers from UCL, Cambridge, and MIT constructed a three-dimensional model to investigate the impact of rocket launches and re-entry in 2019, as well as the impact of expected space tourism scenarios based on the current billionaire space race. The researchers discovered that black carbon (soot) particles generated by rockets areContinue Reading
Back in 1987, world leaders came together to ban chlorofluorocarbons (CFCs), which are the chemicals associated with the gigantic, gaping hole in the ozone layer that persisted for decades. And it’s a good thing that they did. Research published in the journal Nature found that a world in which theContinue Reading
Just as we had gotten over rejoicing at the reports that the ozone hole above the Antarctic was apparently healing, we have some bad news. It turns out that a massive hole has opened up in the ozone layer above the Arctic. The reason this time around seems to beContinue Reading
The ozone layer above Antarctica has recovered so much, it’s actually stopped many worrying changes in the Southern Hemisphere’s atmosphere. A new study suggests the Montreal Protocol – the 1987 agreement to stop producing ozone depleting substances (ODSs) – could be responsible for pausing, or even reversing, some troubling changesContinue Reading
India has successfully achieved the complete phase out of Hydrochlorofluorocarbon (HCFC)-141 b, which is a chemical used by foam manufacturing enterprises and one of the most potent ozone depleting chemical after Chlorofluorocarbons (CFCs). (HCFC)-141 b is used mainly as a blowing agent in the production of rigid polyurethane (PU) foams.Continue Reading
