What is an example of geoengineering?

Examples of this approach include: spraying seawater thousands of metres into the air to seed the formation of stratocumulus clouds that will deflect sunlight; installing sun-shields or mirrors in space to reflect the sun; or injecting sun-blocking particulates into space.

What is geoengineering and how does it work?

Geoengineering proposals fall into at least three broad categories: 1) reducing the levels of atmospheric greenhouse gases through large-scale manipulations (e.g., ocean fertilization or afforestation using non-native species); 2) exerting a cooling influence on Earth by reflecting sunlight (e.g., putting reflective …

What is the primary goal of geoengineering?

Overview of proposed approaches. Solar geoengineering, also called solar radiation management, aims to counteract global warming by reflecting solar radiation to space. In principle, to offset the greenhouse gas-induced warming only requires the reduction of a small fraction of incoming sunlight to the Earth.

What is cap and trade means?

Cap and trade is a common term for a government regulatory program designed to limit, or cap, the total level of emissions of certain chemicals, particularly carbon dioxide, as a result of industrial activity. Proponents of cap and trade argue that it is a palatable alternative to a carbon tax.

Is Geo Engineering ethical?

geoengineering does not exist, and needs development along with the science and technology. geoengineering research, on the other hand is not ethical, unless subject to governance mechanisms yet to be developed. The benefits of knowledge outweigh the risks of not knowing.

What are the two common strategies undertaken by Geoengineers?

Terms in this set (18)

• Promote photosynthesis by Fertilizing the Ocean.
• Burying carbon in Soils.
• Biochar.

How much does geoengineering cost?

On the other hand, David Keith tells us that geoengineering could be very inexpensive. According to him, it would cost just $10 billion, or one ten-thousandth of global GDP, whereas its benefits could be more than 1 percent of global GDP—a return one thousand times greater than its cost.

What is California’s cap-and-trade program?

The Cap-and-Trade Program is a key element of California’s strategy to reduce greenhouse gas (GHG) emissions. The Program applies to emissions that cover approximately 80 percent of the State’s GHG emissions. CARB creates allowances equal to the total amount of permissible emissions (i.e., the “cap”).

Why geoengineering is morally wrong?

One of the few issues which ethicists have reached consensus is that it would be morally unacceptable to use geoengineering, in any form, as a replacement for cutting greenhouse gas emissions. To do so would impose unacceptably large risks and costs on vulnerable people and future generations.
