Nắng nóng cực đoan: Từ công trường như ‘chảo lửa’ đến áp lực điện và tăng trưởng kinh tế | VTV24

Key Concepts

• Climate Tax (Thuế khí hậu): Economic losses and increased costs caused by extreme heat.
• Labor Productivity Loss: The decline in output due to high temperatures (threshold >30°C).
• Cooling Demand: The surge in electricity consumption for air conditioning and refrigeration.
• Heat Adaptation: Infrastructure and policy investments to mitigate heat impacts (e.g., Chief Heat Officer, cooling centers).
• Energy Security: The challenge of maintaining power supply amidst peak demand and fuel supply chain disruptions.

1. Economic Impact of Extreme Heat

Extreme heat is no longer just a meteorological phenomenon but a significant economic burden.

• GDP Losses:
  • Germany: Potential loss of $131 billion by 2030 (up to 3% of GDP).
  • Europe: Projected 0.5% reduction in GDP growth this year; up to 1% for Spain, Italy, and Greece.
• Labor Productivity: Productivity drops by approximately 3% for every degree above 30°C.
• Sectoral Damage: Construction, agriculture, transport, and logistics are the most vulnerable. Europe’s economic loss from heat and natural disasters is projected to rise from 43 billion euros (last year) to 126 billion euros by 2050.
• South Asia: Forecasted to lose up to 7% of labor productivity by mid-century due to high heat and humidity.

2. Impact on Labor and Business Operations

• Operational Adjustments: In France, construction companies are shifting work hours to start at dawn and end in the early afternoon to avoid peak heat.
• Worker Vulnerability: In India, outdoor workers face temperatures of 45–47°C, forcing them to reduce working hours from 8–10 hours down to 2–3 hours, directly threatening their livelihoods.
• Investment Logic: Research suggests that for every $1 invested in climate adaptation (infrastructure, protective gear, management models), there is a potential return of $7–$10 in future economic benefits.

3. Shifts in Consumer Behavior

Extreme heat is reshaping global consumption patterns:

• Retail Trends: Increased demand for cooling products (sunscreen sales up 6x in the UK, ice cubes up 3x).
• Tourism: A 74% increase in searches for "cool destinations" (e.g., Iceland saw an 85% spike in flight searches). Southern Europe may lose 10% of summer tourism, while Northern Europe could see a 5% increase.
• Food & Beverage: Sales of cold drinks, ice cream, and barbecue-related foods have risen by over 60%.
• Durable Goods: Despite high demand for air conditioners and refrigerators, sales in some regions (like India) are lower than expected due to price hikes of 8–10%.

4. Energy Crisis and Infrastructure Strain

The "double pressure" of extreme heat and global fuel supply chain issues (e.g., Middle East conflicts) is straining power grids:

• United States: Philadelphia schools closed due to heat; families are utilizing public cooling centers to save on home electricity bills.
• Germany: Spot electricity prices spiked 29% in a single session due to high cooling demand and low wind power output.
• Philippines: Issued "Red Alerts" in May due to power plant failures and record-high demand, leading to potential 7-hour daily power cuts.
• India: Demand hit a record 256 GW, forcing the government to delay coal plant maintenance to ensure supply.
• Southeast Asia: Electricity consumption for cooling has increased more than 7 times over the last three decades (IEA data).

5. Adaptation Strategies

Governments and organizations are implementing proactive measures:

• Urban Planning: Paris has established over 1,400 cooling centers. Athens appointed a "Chief Heat Officer" to use satellite data and thermal sensors to prioritize green spaces and infrastructure improvements.
• Financial Innovation: India is implementing "heat insurance" for female informal workers, providing automatic payouts when temperatures exceed a specific threshold, without the need for damage proof.
• Energy Transition: Accelerated investment in clean energy (wind, solar) and grid modernization is now viewed as an urgent economic requirement rather than just an environmental goal.

Synthesis/Conclusion

Extreme heat acts as a "climate tax" that permeates every layer of the economy—from individual household electricity bills to national GDP growth. The transition from viewing heat as a seasonal inconvenience to an economic crisis is driving a shift in labor management, consumer behavior, and urban infrastructure. While the upfront costs of adaptation are high, the long-term economic benefits and the necessity of maintaining productivity and energy security make these investments essential for future resilience.
