[联合国]：极端高温行动呼吁（英）

Introduction

Context: The United Nations Secretary-General has issued a global call to action on extreme heat.
Impact: Extreme heat is deadly and disrupts economies and societies. Between 2000 and 2019, approximately 489,000 heat-related deaths occurred each year, with significant impacts in Asia and Europe.
Economic Impact: Heat exposure results in labor capacity loss, equivalent to $863 billion in potential income losses in 2022.

Current Situation

Recent Events: Over the past 100 days, heat-related deaths were reported in various countries, including Saudi Arabia, India, Japan, Bangladesh, the Philippines, and the United States.
Climate Crisis: June 2024 was the 13th consecutive month to break global temperature records, and it is increasingly likely that 2024 will be one of the hottest years in recorded history.
Data Sources: Data from the International Labour Organization (ILO), World Health Organization (WHO), and World Meteorological Organization (WMO).

Key Vulnerabilities

Global Workforce: Over 70% of the global workforce—2.4 billion people—are at high risk of extreme heat, leading to 22.8 million injuries and 18,970 deaths annually.
Regional Impact: In Africa, the Arab states, and Asia and the Asia-Pacific, 93%, 84%, and 75% of the workforce are affected by excessive heat.
Labor Productivity: Daily temperatures above 34°C (93.2°F) result in a 50% drop in labor productivity.

Opportunities for Mitigation

Occupational Safety and Health: Measures could save $361 billion annually.
Heat Action Plans: Early warning and response systems are effective adaptation options.
Triple Strategy: Passive cooling, higher energy efficiency, and phasing down of climate-warming refrigerants could benefit 3.5 billion people by 2050.
Economic Benefits: Reducing energy demand in the cooling sector could save populations $1 trillion and the power sector up to $5 trillion by 2050.

Global Response

Mobilization: The UN aims to mobilize global heat, health, and policy experts to address heat risk.
Actions: Concrete measures to ease suffering, increase resilience, manage crises, and mitigate impacts.
Data and Science: Collecting the latest data and science on extreme heat to build resilience and save lives.

Scientific Evidence

Frequency and Intensity: Heatwaves and prolonged periods of excess heat are increasing in frequency, duration, intensity, and magnitude due to climate change.
Global Trends: The year 2023 was the warmest on record, and this trend continued into 2024 with June marking the 13th consecutive month of record global temperatures.

Conclusion

Call to Action: The world must take bold decisions to mitigate the impacts of extreme heat and avoid an even more dangerous future.
Quote: "The world must rise to the challenge of rising temperatures." — António Guterres, United Nations Secretary-General.
