Questions & Answers

Q: What is the speaker's hometown like in terms of climate?

The speaker's hometown is an archipelago with a temperate climate. Until recently, the temperature hardly reached over 35 degrees Celsius. However, there has been a significant change due to global warming, with temperatures reaching over 40 degrees Celsius during the summer.

Q: What are some of the direct consequences of global warming in the speaker's hometown?

Some of the direct consequences of global warming in the speaker's hometown include phenomena like tropical cyclones, dust storms, and heatwaves. These events can have a significant impact on the city and its inhabitants.

Q: How does extreme heat affect the speaker's hometown?

Extreme heat in the speaker's hometown does not make life harder for the inhabitants as their bodies can adapt to high temperatures. However, the cities and infrastructures are not designed to handle such extreme heat, leading to challenges and discomfort for the residents. The speaker mentions that this summer, there was a significant increase in the number of thermal-completion patients, a severe disease caused by exposure to extremely high temperatures.

Q: What are the projections for global temperature rise in the future?

The global temperature has already risen 1.1 degrees Celsius above pre-industrial levels. Due to the continued release of carbon dioxide into the atmosphere, there is a vicious cycle of abnormal climate conditions. Additionally, the thermal expansion of seawater and ice melting contribute to a rise in the global sea level, which could lead to the submergence of coastal cities like Shanghai by the end of the century.

Q: What solutions are proposed to combat the impact of global warming?

The speaker suggests that making cities naturally cooler could be an effective solution. They propose using natural ventilation processes and incorporating new materials that reduce heat absorption and reflect infrared radiation from the ground surface. However, they acknowledge that there is still a long way to go in terms of technological advancement and global authorization for such solutions.

Takeaways

Global warming is a complex issue that requires collective action from all of humanity. Understanding the reality and consequences of global warming can help more people join the efforts to address it. The speaker emphasizes the importance of technological advancements and worldwide cooperation to develop effective solutions to combat the impact of global warming. By working together, we can strive for a more sustainable and resilient planet for future generations.
