As global temperatures creep closer to the 1.5°C threshold and record-breaking El Niño patterns threaten to disrupt weather systems worldwide, a sobering new warning suggests that the greatest threat to humanity may not be the physical climate itself, but our shrinking ability to respond to it.
A study recently published in the journal Environmental Research Letters by researchers from the University of Exeter and the Strategic Climate Risk Initiative (SCRI) argues that current climate modeling focuses too heavily on environmental data—such as melting ice sheets and rainforest dieback—while ignoring the fragile state of the social and economic systems that must drive the climate response.
The authors warn of a “derailment risk,” suggesting that as climate change accelerates, it may trigger a feedback loop that undermines the very institutions required to enact meaningful solutions. According to the research, humanity risks entering a “Hothouse Earth” scenario—defined as global warming exceeding 5°C—not only because of physical climate triggers but because we may lose the collective capacity to maintain the policies and economies necessary to avert catastrophe.
“Existing analysis usually focuses on how natural systems respond to pressures including greenhouse gas emissions, but we argue that this overlooks the social dimension,” said Dr. James Dyke of the University of Exeter. “Worsening climate shocks should lead to stronger climate action—but instead they could weaken our social, political, and economic capacity to respond.”
The paper highlights the danger of “doom loops,” where the consequences of climate change, such as crop failures, droughts, and mass migration, overwhelm the political and economic systems of individual nations. The resulting pressure can lead to political fragmentation, increased military spending at the expense of climate initiatives, and debilitating debt cycles. When these institutions break down, the ability of a society to effectively steward its environment or transition to sustainable energy collapses, potentially locking humanity into a path of irreversible warming.
Laurie Laybourn, a co-author of the study, emphasizes that climate resilience is often misconstrued as purely technical. “When we talk about climate resilience, we usually think of things like energy grids and transport networks, but we also depend on the social institutions that underpin our complex societies,” Laybourn said. “Social threats have generally been missing from climate risk assessments and policies.”
The researchers argue that because social trust and institutional stability are far easier to dismantle than they are to rebuild, the window to prevent a Hothouse Earth may be much smaller than physical indicators alone suggest. They caution that if policymakers wait until physical damage is at its peak to initiate change, they may find themselves navigating that crisis with a hollowed-out, polarized, or bankrupt system, unable to muster the required resources or public will.
To combat this, the study calls for a fundamental shift in how climate risk is calculated. The authors propose that climate policies must move beyond simple emission-reduction targets to include “derailment risk” management. This involves creating economic and social strategies designed to withstand the “duress” of a more chaotic climate.
The goal, the researchers suggest, is to implement policies that serve two functions simultaneously: protecting populations from current climate symptoms while systematically accelerating the move away from fossil fuels. By reinforcing social and institutional foundations now, nations can maintain their agency in the face of worsening disasters.
“We are already seeing how worsening climate change can harm economies and polarize societies,” said Dr. Jesse Abrams, a member of Exeter’s Green Futures Solutions team. “We need to identify and limit ‘derailment’ risks, and reject the notion that there will come a day when what we do no longer matters.”
As the world stares down the barrel of increasingly frequent climate shocks, the message from the research team is clear: maintaining the integrity of our political, social, and economic institutions is not an auxiliary concern—it is the bedrock of climate survival. Without a proactive approach to maintaining the capacity to act, humanity may find its path to safety derailed long before the physical tipping points are reached.
