Oceans as the planet’s dominant climate regulatorThe global ocean covers roughly 71% of Earth’s surface and acts as the primary regulator of climate. It absorbs and redistributes heat and carbon, moderating atmospheric temperature swings, determining weather patterns, and sustaining life-supporting biogeochemical cycles. Two fundamental roles stand out:Heat storage: The ocean has taken up the vast majority of excess heat from greenhouse gas emissions—commonly estimated at over 90% of the planet’s stored excess heat—slowing atmospheric warming but creating long-term thermal inertia that locks in future change.Carbon sink: The ocean absorbs a large fraction of human-emitted CO2—roughly a quarter to a third…

Standards encompass the rules, specifications, testing approaches, and conformity procedures that define the qualities products and services must meet to access a market, covering everything from technical requirements for home appliances and sanitary guidelines for meat to data‑protection practices and private sustainability certifications set by multinational purchasers. By cutting information imbalances and enhancing interoperability, well‑crafted standards can reduce transaction costs, strengthen consumer confidence, and stimulate trade. Yet these same standards may also function, deliberately or not, as obstacles that limit rivals, divide markets, and alter global value chains. Their distributional consequences are significant, as the gains, burdens, and exclusions they…

Uncertainty—whether from financial crises, pandemics, geopolitical clashes, or sudden technological change—creates pressures that push governments and voters toward protectionist policies. Protectionism surfaces as a response to fear, political incentives, and strategic calculation. This article explains the forces that revive protectionism in bad times, illustrates them with historical and recent cases, examines economic mechanisms and consequences, and outlines policy options that can reduce the temptation to retreat behind trade barriers.Historical pattern and recent examplesProtectionism is not a modern anomaly. The 1930s Smoot-Hawley tariffs are the classic example: the United States raised tariffs in an effort to shield domestic producers, while global…
