  • In a new study published in Nature Communications, an international team of researchers under the lead of Sonia Seneviratne, professor for Land-Climate Dynamics at ETH Zurich, has examined the influence of irrigation more closely.
  • The research team found that the effect of global warming contributing to more frequent and intense heat extremes was partly or completely offset by the cooling effect of irrigation over these regions, and South Asia in particular.
  • Over South Asia, irrigation locally reduced the likelihood of hot extremes by a factor of 2 — 8.
