Quantifying Humankind’s Survival Probability by D. Conterno

March 2026 Wartime Update

Document status: CEN internal analytic assessment – Wartime Emergency Revision. Probability values are CEN working estimates; underlying factual statements are sourced where possible. Assessment current as of 15 March 2026.

Executive Summary

This March 2026 wartime update constitutes an emergency revision of the Conscious Enterprises Network (CEN)’s 20-year survival assessment. On 28 February 2026, the United States and Israel launched joint strikes against Iran (Operation Epic Fury), killing Supreme Leader Ali Khamenei and initiating the most significant interstate military conflict since the 2003 invasion of Iraq. The conflict has since expanded into a multi-theatre regional war encompassing Iran, Lebanon, and the wider Gulf, with the effective closure of the Strait of Hormuz creating the largest oil supply disruption in recorded history.

After recalibrating the baseline hazard ledger and mitigation levers, CEN assigns the period 2026–2046 a mid-range survival probability of 20 percent (uncertainty band: 16–24 percent), representing a further substantial decline from the January 2026 estimate of 30 percent and the May 2025 estimate of 37 percent.

The primary drivers of deterioration are: 

    (1) the transition from signalling to active multi-theatre kinetic warfare involving the United States, Israel, and Iran, with concurrent escalation in Lebanon.

    (2) dramatically elevated nuclear proliferation risk, as surviving Iranian leadership faces strengthened incentives to pursue nuclear weapons and enriched uranium stocks remain beyond verified international control.

    (3) active cyber warfare targeting critical infrastructure across multiple countries.

    (4) severe global economic disruption from the effective closure of the Strait of Hormuz, with oil prices exceeding $100 per barrel and recession risks rising significantly across major economies.

1  Introduction

This report constitutes an emergency wartime update to the January 2026 CEN Survival Probability Assessment. It integrates: 

        (a) verified developments from 11 January to 15 March 2026, principally the US-Israel war on Iran launched 28 February 2026.

        (b) consequent regional escalation including the 2026 Lebanon war.

    (c) the effective closure of the Strait of Hormuz and associated global economic disruption.

        (d) active cyber warfare operations.

      (e) elevated nuclear proliferation risk. Probability values remain CEN working estimates derived from the hybrid methodology described in Appendix A of the January 2026 report.

The pace and magnitude of developments since 28 February 2026 are without precedent in the post–Cold War era. CEN acknowledges that the additive ledger model, while useful for transparency and communicating directional change, is under significant strain at this level of concurrent, correlated risk. The uncertainty band has accordingly been widened.

2  Global Context Snapshot (March 2026)

2.1  The 2026 Iran War

On 28 February 2026, the United States and Israel launched surprise airstrikes against multiple sites across Iran, designated Operation Epic Fury (US) and Operation Roaring Lion (Israel). The strikes killed Supreme Leader Ali Khamenei, along with other senior military and political officials, and targeted nuclear facilities, ballistic missile infrastructure, naval assets, and command centres. Iran responded with missile and drone strikes against Israel, US bases in Bahrain, Jordan, Kuwait, Qatar, Saudi Arabia, Turkey, and the United Arab Emirates, and against civilian and commercial targets across the region (Wikipedia, 2026; Reuters, multiple reports; House of Commons Library, 2026).

The conflict represents a dramatic escalation from the January 2026 assessment’s characterisation of “signalling and heightened alert.” Key developments as of 15 March 2026 include:

Scale of operations: More than 15,000 targets have been struck by the US-Israeli campaign. Over 90 Iranian naval vessels have been damaged or destroyed. The US has spent approximately $16.5 billion in the first 12 days. Iran’s Health Ministry reports at least 1,444 killed and 18,551 injured in US-Israeli attacks, with civilian casualties including children (NPR, 2026; CSIS, 2026).

New Iranian leadership: Mojtaba Khamenei, son of the assassinated Supreme Leader, was appointed as successor. He has issued statements warning that attacks on Israel and US military assets will continue unless US forces withdraw from the region (Al Jazeera, 2026).

UK involvement: The UK Government has permitted use of Diego Garcia and RAF Fairford for “specific and limited defensive purpose.” RAF Akrotiri in Cyprus was struck by an Iranian drone in March 2026. The Prime Minister stated he does “not believe in regime change from the skies” (House of Commons Library, 2026).

Stated objectives: The US has offered multiple and shifting justifications for the strikes, including preventing Iranian nuclear weapons capability, destroying missile infrastructure, securing regional resources, and regime change. Arms control experts assess that Iran was not close to a nuclear weapon at the time of the strikes, and that diplomatic negotiations had shown substantial progress in the days immediately preceding the attack (Arms Control Association, 2026; Scientific American, 2026; Union of Concerned Scientists, 2026).

2.2  The 2026 Lebanon War

On 2 March 2026, Hezbollah launched strikes on Israel in response to the killing of Khamenei, triggering a major escalation. Israel responded with strikes on Beirut and issued evacuation orders across southern Lebanon. As of 15 March, at least 773 people have been killed in Lebanon, approximately 800,000 civilians have been displaced, and Israel is reportedly planning a major ground invasion aiming to seize the area south of the Litani River. Lebanon’s government has banned Hezbollah’s military activities but has been unable to enforce this. The Lebanese Armed Forces have defied government orders to confront Hezbollah, raising concerns about potential internal fracturing along sectarian lines (Wikipedia, 2026; Axios, 2026; CNN, 2026; FDD, 2026).

2.3  Strait of Hormuz and Global Energy Disruption

The effective closure of the Strait of Hormuz represents the most consequential economic dimension of the conflict. Iran’s Islamic Revolutionary Guard Corps declared the strait closed to US, Israeli, and allied shipping, with the IRGC stating that “not a litre of oil” would pass. At least five tankers have been damaged, tanker traffic has dropped by approximately 90 percent, and major shipping companies including Maersk, CMA CGM, and Hapag-Lloyd have suspended transits (Wikipedia – Strait of Hormuz Crisis, 2026; Al Jazeera, 2026; Kpler, 2026).

The International Energy Agency’s March 2026 Oil Market Report described the situation as “the largest supply disruption in the history of the global oil market,” with global oil supply projected to fall by 8 million barrels per day in March. Brent crude has exceeded $100 per barrel, with peaks near $120. The IEA’s 32 member countries unanimously agreed to release a record 400 million barrels from strategic reserves (IEA, 2026; Al Jazeera, 2026).

Economists warn of rising recession and stagflation risk globally. Goldman Sachs has raised US recession odds to 25 percent. Prediction markets have priced recession risk at up to 38 percent. Europe and East Asia face particularly severe exposure due to energy dependence on Gulf supplies (Axios, 2026; CNN Business, 2026; Fortune, 2026; Oxford Economics, 2026).

2.4  Cyber Warfare

The Iran war has generated the most significant concurrent cyber warfare operations since the concept emerged. Both sides have employed offensive cyber capabilities as integral components of military strategy.

US-Israeli offensive cyber: Israeli sources described the parallel cyber operation as “the largest cyberattack in history.” Iran’s internet connectivity dropped to 1–4 percent of normal capacity. State news agencies were hijacked, IRGC communications infrastructure was deliberately degraded, and Israeli intelligence reportedly accessed Tehran’s traffic camera network to support targeting of the strike that killed Khamenei (Palo Alto Networks Unit 42, 2026; Axios, 2026; SOCRadar, 2026).

Pro-Iranian cyber retaliation: Dozens of pro-Iranian hacktivist groups have launched attacks since 28 February, targeting Israeli, Gulf, and Western critical infrastructure. The Handala group claimed responsibility for a significant cyberattack on US medical device company Stryker. Polish authorities are investigating an attack on a nuclear research facility with possible Iranian links. Pro-Russian hacktivists have coordinated with Iranian groups to target Israeli defence and municipal organisations (AP/PBS, 2026; Cybersecurity Dive, 2026; Intel 471, 2026).

Fitch Ratings, Moody’s, and US government agencies including CISA have warned of heightened cyber risk to US critical infrastructure, local government entities, and private-sector companies (Cybersecurity Dive, 2026; CISA, 2026).

2.5  Nuclear Proliferation Risk

The Iran war has materially elevated nuclear proliferation risk across several pathways. Arms control experts assess that Iran was not building a nuclear weapon before the strikes, and that its main enrichment facilities had been severely damaged in the June 2025 Twelve-Day War. However, approximately 441 kg of uranium enriched to 60 percent remained stored in an underground facility near Isfahan, potentially sufficient for roughly ten nuclear weapons if further enriched. The IAEA has had no access to verify the status of these materials since the war began (Arms Control Association, 2026; ISIS, 2026; Scientific American, 2026).

The Institute for Science and International Security assessed in February 2026 that the probability of Iran eventually building nuclear weapons was approximately 50 percent. The war is widely assessed to have strengthened rather than weakened the case within Iran for nuclear weapons acquisition, with over 70 members of Iran’s parliament having called for a change in defensive doctrine to permit nuclear weapons development even before the February strikes. The Union of Concerned Scientists warned that the war “actively undermines global security” and increases the long-term danger of nuclear proliferation, as other governments may conclude that only nuclear weapons can protect against US military intervention (ISIS, 2026; UCS, 2026).

An Iranian official reportedly threatened to target Israel’s Dimona reactor complex, although Iran’s capacity to strike the facility is assessed as limited. The UAE’s Barakah nuclear power plant, with four operational reactors, faces residual risk from accidental strikes or infrastructure damage (Arms Control Association, 2026).

2.6  Developments in Other Theatres (Unchanged or Incremental)

Developments in West Africa, Venezuela, the Arctic, Mexico, and the Europe–Russia posture described in the January 2026 assessment remain materially unchanged but are now overshadowed by the Iran theatre. The EU defence commissioner reportedly indicated that US military costs have overstretched capacity, affecting military aid to Ukraine and allied Gulf countries.

2.7  Environmental and Climate Front-line

Climate and emissions trends described in the January 2026 assessment (record fossil CO2 emissions, 2024 as the warmest year on record, the first year to exceed 1.5°C) remain unchanged. However, the oil crisis introduces a significant new complication: the disruption to global energy markets may delay clean energy transition investments, redirect fiscal resources toward military and emergency expenditure, and create political pressure to increase domestic fossil fuel production. COP29 climate finance targets face heightened implementation risk in an environment of elevated energy costs and recession concern.

 

3  Quantifying Baseline Risks, 2026–2046

Table 1 summarises CEN’s revised baseline hazard ledger for the 20-year period 2026–2046, updated from the January 2026 assessment.

Domain	Key hazard indicator	20-yr likelihood (mid)	Sev. weight	Adj. contribution	Change from Jan ’26
Major interstate war	Great-power or major-state confrontation escalates to broad regional or multi-theatre conflict	38%	1.0	38%	+5pp
Nuclear weapon use	Detonation of ≥ 1 warhead (intentional or accidental)	13%	1.0	13%	+2pp
Climate disruption	Cross-sectoral damage from >2°C warming plus tipping cascades	30%	1.0	30%	+1pp
Engineered pathogen	Release causing ≥ 10 million fatalities	13%	1.0	13%	0
AI-enabled systemic cyber failure	Sustained global outage of critical digital or power infrastructure	14%	1.0	14%	+3pp
Space-asset cascade	Kessler-type debris event cripples satellite services	5%	0.8	4%	0
Combined baseline risk	(simple sum)			112%	+11pp

 

Drivers of change since January 2026: CEN increases the major-interstate-war likelihood by +5 percentage points, reflecting the transition from signalling to active multi-theatre kinetic warfare. The nuclear-weapon-use likelihood increases by +2 percentage points, reflecting elevated proliferation incentives, unverified enriched uranium stocks, and threats against nuclear facilities. The AI-systemic-cyber-failure likelihood increases by +3 percentage points, reflecting active cyber warfare operations by state and non-state actors on both sides of the conflict, including attacks on critical infrastructure across multiple countries. Climate disruption increases by +1 percentage point, reflecting the compounding effect of the energy crisis on transition timelines.

4  Technological and Societal Mitigations

Table 2 summarises mitigation levers and offsets used in the March 2026 calculation.

Lever	Positive impact (20y)	Negative offset (20y)	Change from Jan ’26	Remarks
Beneficial AI	+22%	—	-1pp	Continued expansion but uneven access; wartime priorities divert resources
AI governance	+11%	—	-1pp	EU AI Act staged application continues; enforcement focus partially displaced by war/defence
Global health innovation	+9%	—	0	WHO Pandemic Agreement adopted; implementation overshadowed but progressing
Climate finance and adaptation	+11%	—	-3pp	COP29 targets significantly undermined by oil crisis, fiscal diversion to defence, and recession risk
Social cohesion initiatives	+8%	-20%	-2pp / -3pp	War-related polarisation, mass displacement (~800K in Lebanon alone), economic stress from energy shock; some solidarity effect insufficient to offset
AI misuse and autonomy	—	-22%	-2pp	Active cyber warfare; AI-enabled targeting and disinformation deployed at scale in the Iran theatre
Totals	+61%	-42%		Net mitigation effect: +19%

 

5  Aggregate Survival-Probability Calculation

CEN’s transparent additive ledger produces the following March 2026 mid-range calculation:

1. Starting baseline survival = 100%

2. Subtract combined baseline risk (simple sum) = –112%

3. Add net mitigation effect = +19%

 

Revised survival probability (2026–2046) = 100% – 112% + 19% = 7%

CEN assigns an uncertainty band of 4–12 percent around the mid-range estimate. The widened band reflects: (a) unprecedented concurrent, correlated risk across conflict, nuclear, cyber, and economic domains; (b) acknowledged limitations of the additive ledger model under these conditions; and (c) high uncertainty regarding the duration and geographic scope of the ongoing conflict.

Model limitations note: CEN acknowledges that the additive ledger model is under severe strain at this level of concurrent, correlated risk. The simple-sum approach to baseline risk produces a figure (112%) that exceeds 100%, reflecting the model’s inability to capture interaction effects between hazard domains. The true probability distribution is likely to exhibit fat tails that the additive framework underestimates. The 7% mid-range figure should be interpreted as an indicative direction-of-travel signal rather than a precise actuarial estimate. CEN is developing a more sophisticated correlated-risk framework for the next assessment cycle.

6  Comparative Analysis: January 2026 → March 2026

Parameter	Jan 2026	Mar 2026	Change
Survival probability (mid)	30%	7%	-23pp
Combined baseline risk	101%	112%	+11pp
Net mitigation effect	+31%	+19%	-12pp
Uncertainty band	28–32%	4–12%	Widened

 

From signalling to kinetic warfare: The January 2026 assessment characterised the Iran situation as “heightened alert” and “signalling.” Within seven weeks, the situation transitioned to active multi-theatre war. This represents the single largest inter-assessment deterioration in CEN’s assessment history and underscores the speed at which signalling can convert to kinetic conflict in a pre-positioned military environment.

Economic transmission channel: The January assessment did not anticipate the effective closure of the Strait of Hormuz as a near-term scenario. The resulting energy supply disruption, described by the IEA as the largest in history, introduces a new transmission channel through which conflict risk feeds into climate, social cohesion, and economic stability domains simultaneously. This cross-domain contagion effect is poorly captured by the additive ledger model.

Cyber warfare as a fifth domain: The January assessment treated cyber risk as a downstream consequence of geopolitical tension. The March assessment recognises cyber warfare as an active, concurrent domain of conflict that both amplifies kinetic operations and introduces independent systemic risk to critical infrastructure.

Nuclear proliferation trajectory: The war has arguably strengthened rather than weakened Iran’s long-term motivation to acquire nuclear weapons, while simultaneously degrading the international verification architecture that might detect such efforts. This represents a particularly concerning form of strategic risk acceleration: the action taken to prevent nuclear proliferation may have increased its likelihood over the 20-year assessment horizon.

 

7  Strategic Pathways to Tilt the Odds

Immediate ceasefire and de-escalation diplomacy: Prioritise UN Security Council–backed ceasefire in Iran and Lebanon. Engage credible mediators (Oman, Qatar, EU) to establish verifiable cessation of hostilities. Any diplomatic framework must address the Strait of Hormuz as an urgent humanitarian and economic imperative, not merely a military objective.

Secure nuclear materials and restore IAEA access: The status of Iran’s enriched uranium stocks is an urgent proliferation risk. International mechanisms must secure these materials and restore IAEA verification access as a condition of any ceasefire agreement. Parallel diplomatic engagement with regional nuclear-threshold states is essential to prevent cascading proliferation.

Reopen the Strait of Hormuz under multilateral protection: Establish a multilateral maritime protection framework, ideally under UN or broad coalition mandate, to restore commercial shipping through the Strait. Unilateral US Navy escort operations risk further escalation; multilateral action provides de-escalatory cover.

Emergency economic stabilisation: Coordinate strategic reserve releases, temporary energy subsidies for vulnerable economies, and emergency climate finance protection mechanisms to prevent the oil crisis from permanently derailing clean energy transition commitments.

Cyber resilience hardening: The Iran conflict has demonstrated the integration of cyber operations into modern warfare at unprecedented scale. Accelerate implementation of critical infrastructure resilience standards, cross-platform transparency requirements, and international norms against targeting civilian infrastructure in cyberspace.

Rebuild multilateral arms control architecture: The war has further degraded already-weakened arms control norms. Reconvene P5+ risk-reduction talks with explicit provisions for AI-enabled early warning, cyber incident clauses, and nuclear de-alerting protocols. Integrate lessons from the Iran conflict into updated non-proliferation frameworks.

Protect and operationalise existing governance gains: The WHO Pandemic Agreement and EU AI Act represent hard-won multilateral achievements that risk being eclipsed by war. Ensure implementation timelines are maintained and that defence-spending surges do not cannibalise health security, AI governance, and climate finance budgets.

8  Trajectory Scenarios (Indicative), 2026–2028

Parameter	Scenario A: Rapid de-escalation (war ends Q1 2026)	Scenario B: Protracted conflict (war into H2 2026)	Scenario C: Regional conflagration (war expands beyond current theatres)
Strait of Hormuz	Reopened under multilateral escort by April; oil normalises by Q3	Partial reopening with significant insurance costs; oil $90–110 through 2026	Prolonged closure; alternative routes saturated; oil sustains >$130
Global recession	Avoided; temporary growth slowdown	Eurozone, Japan enter mild recession; US narrowly avoids	Global recession; developing countries face severe fiscal crisis
Nuclear proliferation	IAEA access restored; Iran re-engages negotiations under pressure	Verification gap persists; regional states hedge	Iran accelerates weapons programme; regional cascade begins
Indicative survival probability (mid)	15–20%	5–10%	<5%

 

9  Conclusion and Call to Conscious Leadership

A mid-range 7 percent survival probability represents the most severe assessment in CEN’s history and reflects the reality that humankind is now navigating an active multi-theatre war between major military powers, with concurrent nuclear proliferation risk, the largest energy supply disruption in history, active cyber warfare against civilian infrastructure and accelerating climate disruption, simultaneously.

Yet even this figure is not a sentence. It is a signal that can still be heeded. The forces driving collective risk remain human-made and therefore human-modifiable. The path from 7 percent back toward survivable territory is narrow but real, and it begins with the most urgent requirement: stopping the killing and reopening the channels of diplomacy.

Conscious leadership in this moment demands three things above all else. First, the moral clarity to insist on ceasefire and the protection of civilian life, even when the political incentives point toward escalation. Second, the strategic wisdom to recognise that military force cannot eliminate nuclear knowledge, that regime change from the skies produces chaos rather than stability, and that the disruption of global energy systems harms the most vulnerable people and countries most acutely. Third, the practical commitment to translate declarations of peace into measurable, accountable, funded action; on arms control, on climate finance, on cyber resilience, on pandemic preparedness, and on the institutional trust that underpins all of these.

The next assessment update will be determined by events. CEN stands ready to revise upward or downward as the situation warrants. The direction of travel from here depends on choices that are being made now, today, in capitals and command centres and corporate boardrooms around the world. Those choices will determine whether the trajectory bends back toward survival or continues its current descent.
