Study Finds Droughts Could Last 10 Days Longer by Century’s End
A new study published in Nature reveals that the average duration of the longest annual drought periods could be 10 days longer by the end of this century than previously predicted. This new estimate, based on improved climate modeling techniques, indicates that the risks posed by droughts to societies and ecosystems may be more severe than previously thought.
Researchers led by Irina Petrova and Diego Miralles examined drought projections from multiple climate models under moderate and high-emissions scenarios (IPCC's SSP2-4.5 and SSP5-8.5). They calibrated these projections using historical data from 1998 to 2018, focusing on the longest annual dry spells the number of consecutive dry days each year.
Key Findings
The study suggests that drought periods could extend by 42–44% on ...
