Inventions to Save the Planet

The video explores geoengineering solutions to combat global warming. It discusses placing reflective lenses in space to reduce sunlight, enhancing cloud reflectivity with sea salt, and mimicking volcanic cooling effects by releasing sulfur into the atmosphere. Each method has potential benefits and significant risks, such as high costs and environmental impacts. Geoengineering is presented as an emerging field with innovative technologies aimed at mitigating climate change.

What is the primary goal of deploying reflective lenses into space?

• To enhance satellite communication

• To generate solar energy

• To reduce the amount of sunlight reaching the Earth

• To increase the Earth's temperature

What is the main challenge associated with the cloud enhancement method using sea salt?

• It reduces rainfall

• It is too expensive to implement

• It requires a large amount of seawater

• It causes air pollution

How did the eruption of Mount Pinatubo affect global temperatures?

• It caused a permanent change in climate

• It decreased global temperatures by 0.6°C

• It had no effect on global temperatures

• It increased global temperatures by 0.6°C

What are the potential risks of replicating the cooling effect of volcanic eruptions?

• Increased ocean acidity

• Increased greenhouse gas emissions

• Damage to the ozone layer and respiratory diseases

• Decreased agricultural productivity

What is the focus of the emerging field of geoengineering?

• Innovating technologies to mitigate global warming

• Developing new fossil fuels
