Implication

Analysis reveals rising drought levels in the western Sahel, highlighting climate variability and more extreme outcomes.

Key Points

  • Drought conditions are projected to intensify in the western Sahel, indicating severe climate variability.
  • Instrumental observations show a historical pattern of spatially uniform drought from the Atlantic to the Red Sea.
  • Analysis includes simulations with external climate forcing, revealing a drying trend despite regional recovery efforts.
  • Transition to North Atlantic cooling may exacerbate drought conditions, leading to significant regional disparities.
