And no one has a plan.
A new actuarial report compares the climate crisis to the 2008 financial crisis — and warns that carbon budgets are already in the red.
In January 2026, the Institute and Faculty of Actuaries (IFoA) and the University of Exeter published one of the most compelling climate risk analyses of recent years. Its title: “Parasol Lost: Recovery Plan Needed.” Its message: we are at a “breaking point,” and we still have the power to change course—but time is running out.
“We have reached a point comparable to
that of the global financial crisis. Emergency
action is needed to stabilize the
climate system.”
What is the “lost umbrella”?
For decades, the burning of fossil fuels has had an unintended side effect: aerosols—particles of pollution—acted as a sunshade, reflecting sunlight and reducing global warming by approximately 0.5°C.
It was accidental geoengineering on a planetary scale.
The problem: as we clean up the air—through new regulations on
marine fuel and industrial filters—that umbrella effect is fading. The temperature, which has been artificially suppressed for years, is now rising sharply. The authors call it “termination shock”: the shock of the umbrella being withdraw
- 1.4°c warming already reached above pre-industrial levels (decade-long average)
- 0.5°c additional cooling that aerosols have masked so far
- 2°c catastrophic warming likely before 2050 if no action is taken
- 534 ppm co₂ equivalent in the atmosphere by 2023 — nearly double the pre-industrial level
- ×6 multiplier for insured losses from natural disasters since 2000
- −50% projected decline in global gdp in the worst-case scenario without mitigation
The analogy that changes everything: 2008
The report draws a comparison worth noting: the global financial crisis of 2007–08. At that time, financial models failed to capture the interconnected nature of the system. There was widespread complacency, flawed models that no one questioned, and an institutional inability to recognize systemic risk until it was too late.
The 9 key findings of the report
- Global warming is accelerating: The rate has risen from 0.18°C per decade to 0.27°C per decade over the past ten years.
- The artificial sunshade is fading: Cleaner air is eliminating the cooling effect of polluting aerosols, accelerating warming.
- Higher-than-expected climate sensitivity: Three independent sources indicate that the climate is more sensitive to CO₂ than the IPCC’s central estimate.
- Carbon budgets are negative: With high climate sensitivity, the budgets calculated for 1.5°C have already been exhausted.
- Tipping points: Greenland ice sheet melt, methane from permafrost, and the collapse of the AMOC.
- Severe economic impact: Climate-related damages will exceed global GDP growth between 1.5°C and 2°C of warming.
- Insurance is pulling out: Insured losses from natural disasters nearly doubled between 2015 and 2024.
- Nature is our greatest ally: Forests, oceans, and soils are critical carbon sinks that we must protect and restore on a strategic scale.
- There is still agency: The energy transition, methane reduction, curbing deforestation, and emergency technologies can change the trajectory.
What this means for businesses
This report is not just about climate science. It is a roadmap of
physical, financial, and reputational risks for any company
operating in the real world. The withdrawal of insurance from coastal areas,
climate-driven inflation in agri-food supply chains,
water disruptions in industrial regions: these are no longer
distant scenarios.
Actuaries don’t usually use the language of activism. When
they say “insured losses could reach $250
billion annually by 2035” or “the drop in GDP in a
no-mitigation scenario could exceed 50%,” they are speaking
in the only language the markets understand: probabilities and
expected losses.
Companies that continue to ignore this are not brave; they are reckless. And those that embrace it as an opportunity—in terms of resilience, transition, and purpose—are the ones that build a long-term competitive advantage.
From an economic standpoint, minimizing climate risks by reducing emissions will have overwhelmingly positive consequences, helping to avoid short-term economic shocks and long-term decline.

The recovery plan they are proposing
The report does not stop at a diagnosis. It proposes a Planetary
Solvency Recovery Plan—similar to the solvency recovery plans
that financial regulators require of banks —with five key areas of action:
- A shift in mindset: from unintended planetary consequences to active and intentional planetary stewardship. Businesses and governments must see themselves as stewards of the Earth system, not as actors external to it.
- Quick wins: reducing methane by 30% by 2030 (methane has 80 times the greenhouse effect of CO₂ over 20 years) and halting global deforestation, which in 2024 resulted in the loss of 30 million hectares of natural forest.
- Accelerate the energy transition: not as a sacrifice, but as a classic technological disruption—like the Model T or the iPhone—with enormous economic potential. The report notes that fossil fuel subsidies amount to between $1.5 trillion and $7 trillion annually: there lies political and financial leverage.
- Working with nature at scale: protect and restore large natural carbon sinks—the Amazon stores the equivalent of 20 years of global CO₂ emissions—and marine ecosystems.
- Research and deploy emergency brakes: 5. Research and deploy emergency brakes: 5. Research and deploy emergency brakes: solar radiation management and CO₂ capture technologies that, while not a substitute for emissions reductions, can buy critical time.
An interpretation from the perspective of the purpose-driven economy
At ImpactCo, we have been arguing for over 20 years that
this report confirms through actuarial models: optimization without
purpose is destruction deferred. The economic model that only
maximizes short-term profitability was not designed to
manage planetary risks—and it is failing in a
systemic way.
The concept of “planetary solvency” is not a metaphor: it is
literally the Earth system’s capacity to continue
providing the ecosystem services that sustain the
real economy. Water, food, a stable climate, biodiversity. If
that collapses, no balance sheet can withstand it.
The good news this report brings—and which is sometimes lost
in the noise—is that we still have agency. Companies that
integrate this perspective into their strategy not only manage
risk better: they build the kind of value that the next economic
cycle will reward. The rest are taking unmodeled risks.
Is your company modeling its physical and transition climate risks? Or is it still operating based on assumptions from the last century?
