Removing CO2 From the Air Efficiently

Canadian scientists have created a device that efficiently removes CO2 from the atmosphere. "The proposed air capture system differs from existing carbon capture and storage technology ... while CCS involves installing equipment at, say, a coal-fired power plant to capture CO2 produced during the coal-burning process, ... air capture machines will be able to literally remove the CO2 present in ambient air everywhere. [The team used] ... a custom-built tower to capture CO2 directly from the air while requiring less than 100 kilowatt-hours of electricity per tonne of carbon dioxide."

CO2 is good

[bradley13]

If (a) global warming is actually happening (b) CO2 is the cause, then there are still two things to consider:

• A warmer planet is good. They didn't call it the Medieval Climate Optimum for nothing. A warmer climate leads to more arable land and longer growing seasons.
• CO2 is good - it is the world's best fertilizer. The increase in CO2 levels has increased crop yields up to 30% (depending on the specific crop and local climate).

Of course, all recent evidence points to warming having ended, and having been due to natural climate variability and/or solar cycles.
