3 Extreme Climate Fixes

The video discusses geoengineering as a means to combat climate change, presenting three main strategies: modifying clouds to reflect sunlight, fertilizing oceans to increase CO2-absorbing phytoplankton, and injecting sulfur dioxide into the stratosphere to cool the planet. Each method has potential benefits and risks, highlighting the complexity of addressing global warming.

What is the primary goal of geoengineering as discussed in the introduction?

• To increase the Earth's temperature

• To reduce the Earth's natural resources

• To alter climate systems to mitigate global warming

• To eliminate the use of fossil fuels

How do geoengineers propose to modify clouds to help with climate change?

• By using airliners to spray compounds on cirrus clouds

• By increasing the number of rain clouds

• By reducing the size of all clouds

• By removing clouds from the atmosphere

What is a potential negative effect of fertilizing oceans with iron?

• Increased fish population

• More frequent hurricanes

• Creation of dead zones due to oxygen depletion

• Higher global temperatures

What is the proposed method for creating a 'shady stratosphere'?

• Increasing the Earth's albedo

• Building large umbrellas on Earth

• Launching mirrors into space

• Spraying sulfur dioxide into the stratosphere

What could be a consequence of reducing sunlight through geoengineering?

• Decreased annual rainfall

• Higher temperatures at the equator

• Increased global rainfall

• More sunlight reaching the poles
