World Economics
Economic growth is increasingly dependent on narrow, high-risk drivers. Tariffs, immigration constraints, and AI capital spending now interact to produce misleading headline GDP growth.

Tariffs and Trade Distortion
Tariffs raise production costs, suppress demand, and distort GDP accounting by reducing imports rather than increasing real output.
Immigration and Labor Supply
Immigration accounted for an estimated 80% of U.S. GDP growth (2020–2025). Reduced labor inflows weaken consumption, payroll growth, and long-term output.
AI Capital Spending Risk
AI-related data center investment explains an outsized share of GDP growth, despite uncertain productivity returns and expanding circular financing risk.
World Climate
The climate system has entered a phase of runaway, nonlinear acceleration. Stabilizing feedbacks are failing. Cascading collapse is now observable across atmospheric, ecological, and economic systems.

Tipped Tipping Points
Doubling time of climate impacts has collapsed to < 2 years. Carbon sinks are now net carbon sources.
The Domino Effect
Interacting failures — wildfires, permafrost thaw, AMOC slowdown, ecosystem collapse — amplify one another in cascading feedback loops.
Human Consequences
Heat mortality, insurance collapse, forced migration, food and water insecurity are no longer future risks.
Health & Wellness
Human health outcomes are shaped by education, environment, diet, physical activity, and climate stress — all operating within accelerating feedback loops.

Education & Awareness
Financial literacy, nutrition education, and wellness awareness reduce healthcare burden and improve resilience.
Fossil Fuels & Health
Air pollution from fossil fuels remains the leading global cause of premature death — amplifying climate-driven disease.
Movement & Incidental Activity
Walking, stair climbing, gardening, and daily movement reduce mortality risk and cognitive decline — especially under rising heat.
