Introduction

The Paris Agreement has a goal of limiting global warming well below 2°C, ideally 1.5°C. Understanding the local-level impacts of these global temperature targets is crucial for informing climate change adaptation needs and actions. To date, mitigation pledges by nations fall far short of what is needed, with the world on track to warm by 3.2°C by the end of the century.

This infographic* produced by the Adaptation at Scale in Semi-Arid Regions (ASSAR) project sumarises the impacts of  warming scenarios from 1.5-3°C in Ghana.

Impacts of 1.5°C and higher in Ghana

  • For Ghana, local warming will be greater than the global average.
    • Even a 1.5°C increase in global temperature will have severe local impacts, affecting water resources, agriculture, sea level rise, fisheries, health, and other vulnerable sectors.
  • Under an increasing emissions trajectory, the 1.5°C threshold could be breached within the next decade, and the 2°C threshold the decade after.
  • This means there is an urgent need to accelerate Ghana’s adaptation responses to support its development agenda.
