KBS 다큐세상 인류의한계 온도1.5도씨

Summary

The documentary argues that human emissions of carbon dioxide, produced largely through energy use and industry, are warming the planet. It presents the 1.5°C limit above pre-industrial temperatures as a critical goal and says the global average had already risen by about 1°C at the time described.

Under the high-emissions RCP 8.5 scenario, the film cites projections of roughly 4°C of global warming by 2100 and about 4.4°C for the Korean Peninsula. It warns that Korea could face a much longer summer, more heatwaves and tropical nights, and greater difficulty living and working outdoors.

The film describes several climate-related risks:

• More extreme heat, including the exceptionally hot summer of 2018 in Korea.
• Potentially more damaging autumn typhoons, which can intensify over warmer seas.
• Shifts in disease or virus outbreaks, though the relevant subtitle is unclear.
• A sharp decline in suitable apple-growing areas by 2100 under continued high emissions.
• Threats to food security: Russia’s 2010 drought disrupted grain exports, and rising grain prices can contribute to social conflict.

Accurate greenhouse-gas measurement is important for identifying where emissions originate and informing climate diplomacy. Korea’s monitoring stations include Anmyeondo, Jeju, and Dokdo. The film notes that measurements at Anmyeondo are high for its latitude, while the precise domestic or cross-border sources are difficult to determine.

Examples of climate responses presented include:

• United Kingdom: A Climate Change Commission advises the government on reducing emissions. Nottingham aims to become a zero-carbon city by 2028, with trams and park-and-ride schemes, as well as retrofits to reduce emissions from older homes.
• Germany: Urban forests are described as a way to reduce the urban heat-island effect.
• France: Green roofs can provide insulation and store rainwater. The film also describes ventilation that transfers heat between incoming and outgoing air, reducing the need for heating or cooling.
• Busan: The city is monitoring projects intended to protect climate-vulnerable residents and respond to urban warming.

The film concludes that the goal is not to “save” the planet itself, but to protect human societies and future generations from the consequences of rapid climate change.
