Recommendation

Researchers from the Cluster of Excellence program CLICCS (Climate, Climatic Change and Society) have assessed the possibility of limiting global warming to 1.5°C higher than preindustrial levels. They find that social and natural-world trends make achieving that goal unlikely. They analyze climate threats, including deforestation and melting ice sheets, and offer detailed analyses of trends in fossil-fuel divestment, consumption and climate protests. CLICCS offers steps to limit warming to below 2°C, an achievable goal.

Take-Aways

  • Nations will not meet the Paris Agreement’s temperature targets.
  • Social drivers play essential roles in attaining climate goals.
  • Physical processes will have at most a moderate impact on meeting temperature goals.
