NIWA scientists are predicting that this year’s ozone hole will stay around for longer than usual, potentially lasting into early summer. ☀️ This is largely due to a combination of climate change and the 2022 Tonga volcanic eruption, says NIWA Principal Scientist – Atmosphere and Climate, Dr Olaf Morgenstern. “Hunga-Tonga-Hunga Ha’apai blasted an astonishing amount of water into our atmosphere. In fact, we are seeing around 10% more water vapour than usual.” 🌋 Water vapour is a greenhouse gas that causes cooling of the stratosphere and enhances the depletion of ozone by forming clouds above Antarctica. ☁️ Scientists at NIWA’s Lauder Atmospheric Research Station are measuring the chemistry in the atmosphere to understand what exactly is going on.
