World-first research conducted by Australian researchers has highlighted the role that cold fronts play in making bushfires drastically worse – posing a serious concern for future bushfire events. Research conducted by UNSW Canberra and the Australian National University studied the impact of cold fronts during the devastating 2019-20 Black Summer bushfires, and found they increased dangerous bushfire conditions and led to bigger and more erratic fires. By studying sea level pressure charts and the significant temperature drops associated with cold... View Article

Originally published by Scimex The Bureau of Meteorology has confirmed it is not yet declaring El Niño, despite the World Meteorological Organization declaring the onset of El Niño conditions on Tuesday. They say while BOM metrics indicate a 70% chance of an El Niño event occurring before summer, the set of indicators they use have not yet passed the threshold to declare an event underway. Below, Australian experts discuss what El Niño would likely look like for Australia. Organisation/s: Australian Science Media Centre, Bureau of... View Article

Originally published at Scimex The World Meteorological Organization is warning that there is a 98% likelihood that at least one of the next five years will be the hottest on record, thanks to the combination of El Niño and climate change. The latest global Annual to Decadal Climate Update also warns there is a 66% chance that annual global surface temperature will temporarily exceed 1.5°C above pre-industrial levels for at least one of the next five years. While this doesn’t mean that we... View Article

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
