The study finds that while human-induced climate change did not significantly alter the likelihood of the overall 24-month rainfall deficit, it drastically increased drought severity through higher temperatures and evapotranspiration. In a world 1.2°C cooler, the combination of low rainfall and high evapotranspiration observed would not have led to drought; however, in the current climate, it is classified as an 'exceptional drought'. The researchers estimate that such droughts have become approximately 100 times more likely due to climate change.
