Geoengineering Climate Change, by Jennifer Swanson

96 pages; ages 8-12. Twenty-First Century Books, 2017

Floods! Tornadoes! Super-hurricanes! Blizzards! Wildfires! Mudslides! These weather events and catastrophes have been increasing in the past couple decades and are related to climate change caused by a warming earth. Most scientists agree that human activity – primarily burning fossil fuels – is responsible. And of we don’t take action to prevent further warming, we’ll see even more drastic changes.

What can we do? The most obvious solution would be to stop burning fossil fuels. But some engineers propose we tackle the problem with … engineering. The propose constructing large-scale technologies to counteract climate change. Installations that would physically remove carbon from the air, or sequester carbon somehow. Some engineers propose crating artificial clouds to shade the earth, or send mirrors into space to reflect sunlight. Or shooting salt into clouds to make it rain.
