Even at current levels of warming, Earth’s systems are showing signs of tipping into irreversible change. As this stark report highlights, the 1.5°C is neither safe nor defensible as a policy goal.

Summary

  • Tipping points loom as small changes trigger larger, abrupt and irreversible shifts.
  • Cascading risks emerge as interconnected tipping points amplify global impacts.
  • Polar instability accelerates the impacts, with Antarctic and Arctic changes driving sea-level rise.
  • Ecosystem decline intensifies as Amazon becomes a carbon emitter and coral reefs collapse.
  • Paris targets fail, with 1.2°C warming surpassing critical climate thresholds.

Cascading Climate Risks

The accelerating risks of climate tipping points provide a stark warning about the cascading effects of global warming. This report reveals how critical systems like Antarctica, the Arctic, Greenland, the Amazon rainforest, and coral reefs are reaching thresholds of irreversible change. These shifts, often driven by self-reinforcing feedback loops, are already destabilising ecosystems and intensifying threats like sea-level rise and carbon emissions.

With evidence showing that the Paris Agreement’s 1.5–2°C targets are insufficient to prevent catastrophic impacts, this report underscores the urgent need for restorative climate action. The report offers a compelling call to rethink current climate strategies and confront the realities of a rapidly changing Earth.

 

The report’s foreword is written by Professor Sir David King FRS, one of the world’s most respected climate scientists. Sir David is the former Chief Scientific Adviser to the UK Government, founder of the Centre for Climate Repair at Cambridge, and Chair of the Climate Crisis Advisory Group. In his foreword, he warns that while the IPCC has laid bare the scale of the climate emergency, it fails to fully account for the escalating risk of irreversible tipping points. He describes Climate Dominoes as a vital and urgent analysis, and a call to action for governments, financial leaders, and the scientific community to respond to the climate crisis with the seriousness and speed it demands.

This is a code red situation. No government is taking it seriously enough. We must urgently seek productive collaboration between sub-national, national, and international bodies to do more to combat climate issues equitably, with determination and speed.

Climate Dominoes

Earth’s systems are showing significant signs of tipping into irreversible change.
