      Scientists observe the ozone layer hole above Antarctica shrinking: Is Earth recovering?

      ecent findings show the Antarctic ozone hole this year is smaller and formed later than expected, raising questions about whether Earth is on the path to healing.

    • Ozone hole largest on record over past 3 years, new research finds

      Ozone hole largest on record over past 3 years, new research finds

      According to the study’s lead author Hannah Kessenich, PhD candidate at the University of Otago, New Zealand, the team found much less ozone in the centre of the hole compared to 19 years ago.

    • Ozone hole above Antarctica is now three times the size of Brazil

      Ozone hole above Antarctica is now three times the size of Brazil

      Currently, the ozone hole spreads across 26 million square kilometres.

    • Climate Change: The 36-year-old treaty slowing the Arctic meltdown

      Climate Change: The 36-year-old treaty slowing the Arctic meltdown

      Governments came together in 1987 to sign the Montreal Protocol to address the problem of CFCs eating away at the Ozone layer. That agreement has been a resounding success, and a template for subsequent climate accords. It has prevented an additional 443 million cases of skin cancer by 2100  in US alone and the Arctic Ocean’s first ice-free summer will come about 15 years later

    • Ozone layer recovery delayed, surface UV radiation rising: Study

      Ozone layer recovery delayed, surface UV radiation rising: Study

      Despite projections that the ozone layer would fully recover by mid-century, researchers found rising UV radiation levels in the tropics and northern mid-latitudes after 2010, posing risks to human health and the environment.

    • Ozone hole above Antarctica is filling up, thanks to the success of Montreal Protocol

      The Ozone layer is on track to mend itself within decades due to success of Monetreal protocol, finds a recent UN study. Take a look…

    • Ozone heating Earth more than previously thought: Study

      Ozone heating Earth more than previously thought: Study

      The researchers found that changes to ozone levels in the upper and lower atmosphere were responsible for almost a third of the warming seen in ocean waters bordering Antarctica in the second half of the twentieth century.

    • China’s emissions of ozone-harming gas are declining, studies find

      China’s emissions of ozone-harming gas are declining, studies find

      The findings ease concerns that increased emissions of the gas would slow progress in the struggle to repair the ozone layer, which blocks ultraviolet radiation from the sun that can cause skin cancer and damage crops
