EXPERT REACTION: Satellite observations show worldwide water extremes increasing since 2002

March 14, 2023 4:27 pm Published by Comments Off on EXPERT REACTION: Satellite observations show worldwide water extremes increasing since 2002

Originally published by Scimex The global intensity of water cycle extremes — which includes the extent, duration, and severity of droughts and floods — increased from 2002-2021 according to international research that used satellite data to quantify wet and dry extreme events around the world, including from Australia. The authors found that there was an excess of intense droughts and extreme wet events during 2015–2021, which were also the hottest seven years on record. The team found that Australia’s Millennium Drought... View Article
