Human-induced climate change threatens human civilisation. Special precautions that go well beyond conventional risk management practice are required if the increased likelihood of very large climate impacts — known as “fat tails” — are to be adequately dealt with.

Summary

  • Human-induced climate change is an existential risk to human civilisation.

  • The bulk of climate research has tended to underplay these risks, and exhibited a preference for conservative projections and scholarly reticence.

  • IPCC reports also tend toward reticence and caution, erring on the side of “least drama”, and downplaying the more extreme and more damaging outcomes.

  • This is a particular concern with potential climatic tipping points such as the polar ice sheets, and permafrost and other carbon stores.

  • The extreme risks to humanity which the tipping points represent justify strong precautionary management.

  • If climate policymaking is to be soundly based, a reframing of scientific research within an existential risk-management framework is now urgently required.

The Failure to Assess Climate Reality

The consistent understatement of existential climate risk by governments, institutions, and even parts of the scientific community is a critical issue. This report examines how and why this downplaying has occurred, revealing a persistent pattern of minimisation, delay, and false optimism that has distorted public understanding and policymaking for decades.

Drawing on the latest science and expert risk assessments, the report shows that current trajectories point to catastrophic outcomes—far beyond what mainstream discourse admits. It argues that the failure to confront these risks truthfully is not just a policy failure, but a profound moral and leadership crisis.

This report cuts through the noise. It calls for honest assessment, emergency-level action, and a new standard of responsibility from those in power.

Foreword by a Leading Voice on Climate Risk

What Lies Beneath opens with a powerful foreword by world-renowned climate physicist Hans Joachim Schellnhuber—founding director of the Potsdam Institute for Climate Impact Research and senior advisor to the EU, German government, and the Vatican. Drawing on decades at the forefront of climate science, Schellnhuber endorses this report as a vital intervention from outside the conventional scientific establishment.

He warns that mainstream institutions like the IPCC, constrained by consensus-building and a bias toward caution, have consistently underplayed the existential risks we now face. In contrast, What Lies Beneath dares to speak the unspeakable—about the systemic understatement of climate threats, the failure of risk frameworks, and the urgency of transformative action. In Schellnhuber’s words, the report helps reveal what orthodox science may overlook—at a moment when “the wolf may already be in the house.”

Climate change is now reaching the end-game, where humanity must choose between unprecedented action or bear the consequences.
