Context:
A joint report by the World Health Organization (WHO) and the World Meteorological Organization (WMO) warns that rising global temperatures are increasingly harming workers’ health and reducing productivity worldwide.
Key Highlights:
- Rising Heat Levels: 2024 was the hottest year on record; daytime temperatures of 40°C–50°C are becoming more frequent.
- Health Impact: Workers face higher risks of heatstroke, dehydration, kidney dysfunction, and other heat-related illnesses.
- Economic Impact: Productivity drops 2–3% for every degree above 20°C, making this not just a health issue but also an economic challenge.
- Affected Sectors: Outdoor manual labourers in construction, agriculture, and fisheries are the most impacted.
- Geographical Scope: Impacts are global, not limited to equatorial nations; nearly half of the world’s population faces adverse effects of heat.
- Proposed Solutions:
- Adjusting work hours to avoid peak midday heat.
- Encouraging “siesta culture” in temperate regions.
- Workplace policies to mitigate heat exposure.
Tourism Impact – Rise of ‘Coolcations’
- Extreme heat waves and wildfires are reshaping global tourism trends.
- Europe: Northern coastal regions may see +5% tourist demand, while southern Europe could lose ~10% of summer tourists.
- Asia & US: Visitor numbers fell at Tokyo Disney Resort; Six Flags Entertainment in the US lost $100M in Q2 due to severe weather.
- Emerging Destinations: Colder regions like Antarctica, Norway, and Iceland are witnessing a surge in popularity.
Global Warming
Global warming refers to the long-term rise in Earth’s average surface temperature due to increasing concentrations of greenhouse gases (GHGs) in the atmosphere. It is a major aspect of climate change, caused largely by human activities.
Causes:
- Greenhouse Gas Emissions:
- Carbon dioxide (CO₂) from burning fossil fuels (coal, oil, natural gas).
- Methane (CH₄) from agriculture, livestock, and landfills.
- Nitrous oxide (N₂O) from fertilizers and industrial processes.
- Fluorinated gases from refrigerants and industrial chemicals.
- Deforestation: Reduces the planet’s ability to absorb CO₂.
- Industrialization: Increased energy consumption and waste production.
- Urbanization: Concrete and asphalt absorb heat, contributing to local warming (“urban heat islands”).
