A five-year drought currently impacting Iran and teh broader Middle East has been definitively linked to human-caused climate change, according to a new study released today.The analysis, from the World Weather Attribution initiative, underscores a rapidly worsening water crisis in a region already facing significant political and economic instability. Researchers now state that a drought of this intensity and duration woudl have been exceedingly rare without the influence of rising global temperatures,and is becoming increasingly commonplace. The report highlights not only the effects of climate change, but also the role of local factors in exacerbating the situation, including strained water resource management and land use practices.
A five-year-long extreme drought gripping Iran and parts of the wider Middle East would not have occurred in its current form without human-caused climate change, according to a new study.
The warming driven by fossil fuel emissions is largely responsible for pushing the region into a state of “exceptional drought,” impacting countries including Iraq and Syria, researchers found.
The analysis, conducted by the World Weather Attribution (WWA) initiative in London, identifies the current drought in Iran as the most severe on record.
Climate Change is Making Rare Droughts the New Normal
This latest assessment builds on a previous WWA analysis from 2023, with expanded data extending to June 2025 revealing an even stronger link to climate change than previously understood. A five-year dry spell like the one the region has experienced since 2020 is now considered a relatively common occurrence in the warmer climate of today.
However, such a prolonged drought would have been expected only once or twice per century in a world without climate change, and would have been significantly less intense.
The study also points to structural issues exacerbating the water crisis, including inadequate and overburdened water management practices, overgrazed lands, and expanding agricultural activity throughout Iran and neighboring countries.
