Montreal Protocol and Climate Change

The video discusses the thinning of the ozone layer in the 1980s and the global response through the Montreal Protocol, which banned CFCs. This treaty not only helped the ozone layer recover but also significantly slowed global warming. Without it, temperatures would be much higher, affecting climate targets. The video highlights the importance of global cooperation and innovation in addressing environmental issues.

What was the primary cause of the thinning ozone layer discovered in the 1980s?

• Increased solar activity

• Deforestation

• CFC emissions

• Volcanic eruptions

Which international agreement was established to address the depletion of the ozone layer?

• Montreal Protocol

• Geneva Convention

• Paris Agreement

• Kyoto Protocol

How did the Montreal Protocol contribute to slowing global warming?

• By eliminating CFCs, potent greenhouse gases

• By banning deforestation

• By reducing carbon dioxide emissions

• By promoting renewable energy

What would have been the impact on global temperatures by 2050 without the Montreal Protocol?

• Temperatures would have remained stable

• Temperatures would have been slightly lower

• Temperatures would have decreased

• Temperatures would have been significantly higher

How much more would Australia have warmed by 2050 without the Montreal Protocol?

• 1.5 °C

• 0.5 °C

• 1.0 °C

• 2.0 °C

What lesson does the success of the Montreal Protocol teach us about addressing global issues?

• Individual efforts are more effective

• Global cooperation can lead to significant achievements

• Ignoring scientific evidence is beneficial

• Economic growth should be prioritized over environmental concerns

Why was the response to the ozone layer issue so decisive in the 1980s?

• It was not considered a serious issue

• The problem was invisible

• There was no scientific consensus

• People could visualize the problem through images

What false sense of security do people have regarding climate change?

• That it is an unsolvable problem

• That it is a distant problem

• That it is a problem only for scientists

• That it is a fast-changing problem

What was one of the benefits of the Montreal Protocol beyond environmental health?

• It increased reliance on fossil fuels

• It forced industries to innovate

• It stifled technological innovation

• It led to economic recession

How does addressing climate change present economic opportunities?

• By limiting economic growth

• By decreasing global cooperation

• By growing the renewable energy sector

• By reducing the need for new technologies
