Findings of new Research

  • Researchers have analysed 70 years of reliable sea surface temperature records in the Pacific Ocean to model changes in the El Niño-Southern Oscillation (Enso) under current projections of global heating.
  • Previous research had suggested that climate change-driven variability of ENSO events would not be detectable until 2070.
  • New findings: ENSO variations would be detectable about 40 years earlier than suggested by previous modelling.



  • We should be more prepared for prolonged droughts and extreme flooding in the future.
  • Flooding is more destructive than drought in terms of infrastructure, but drought is very impactful in terms of agriculture – both sides of the coin have substantial economic losses.
