Shift to ‘flash droughts’ as climate warms
‘Flash droughts’ have become more frequent due to human-caused climate change and this trend is predicted to accelerate in a warmer future, according to research published today [13 April 2023] involving the University of Southampton.
The research published in Science shows that flash droughts, which start and develop rapidly, are becoming ‘the new normal’ for droughts, making forecasting and preparing for their impact more difficult.
Flash droughts can develop into severe droughts within a few weeks. They are caused by low precipitation and high evapotranspiration, which quickly depletes the soil of water. While they start quickly, the droughts can last for months, damaging vegetation and ecosystems, and triggering heat waves and wildfires.
