Researchers at the Massachusetts Institute of Technology (MIT) predict that the global ocean could become a measurable source of ozone-depleting CFC-11 in the future. Commonly used as a refrigerant, propellant and foam blowing agent, CFC-12 was phased out in 2010 – although there has been some illegal use since. Nevertheless, atmospheric levels of CFC-11 are Continue reading Warming oceans could start emitting absorbed CFCs

Biosignatures have long played a part in the search for other life in our universe. These signatures are chemical elements or substances, such as methane detected in the atmosphere of a planet, that are naturally produced by living organisms. However, scientists at the Massachusetts-based Centre for Astrophysics and the University of Rochester are collaborating on Continue reading CFCs could reveal life on other planets

The World Meteorological Organisation (WMO) has reported that ozone layer depletion reached record levels over large parts of the Arctic in spring. Monitored ozone levels over the Arctic in March are typically at least 240 Dobson Units (DU) – with a DU representing a 0.01mm-thick layer of pure ozone at standard temperature and pressure (STP). Continue reading Extreme weather, CFC damage result in record Arctic ozone depletion
