TED: Can we stop climate change by removing CO2 from the air? | Tim Kruger

The video discusses the urgent need to cut emissions and remove carbon dioxide from the atmosphere to combat climate change. It explores various techniques, including using plants and artificial trees, and introduces the Origin Power Process, which uses natural gas to generate electricity while removing CO2. The potential of using lime to counteract ocean acidification is also discussed, along with the challenges and governance required for these solutions. The importance of ambition and the role of future generations in addressing climate change are emphasized.

What is the main reason for the urgency in cutting emissions rapidly?

• To reduce global population

• To increase industrial growth

• To prevent economic collapse

• To avoid dangerous climate change

What is the key feature of the natural gas process discussed in the video?

• It is cheaper than renewable energy sources

• It requires no initial investment

• It generates more electricity than traditional methods

• It produces pure carbon dioxide for storage or use

How does the lime process potentially benefit the environment?

• By enhancing coral reef development

• By promoting fish population growth

• By reducing ocean acidification

• By increasing ocean temperatures

What is a major concern regarding the use of lime in oceans?

• The high cost of lime production

• The unknown environmental consequences

• The lack of available lime resources

• The difficulty in transporting lime

What is the estimated cost of removing trillions of tons of CO2 from the atmosphere?

• Half of the global GDP

• A few percent of GDP

• No additional cost

• A quarter of the global GDP

What is emphasized as crucial in addressing climate change?

• Ignoring speculative ideas

• Individual efforts

• Immediate results

• Ambition without arrogance

Who is expected to complete the task of restoring the atmosphere?

• Private companies

• Future generations

• Political leaders

• Current scientists
