How about producing less CO2 in the first place and planting trees to reduce CO2 concentration
- corty 5y agoPlanting trees uses too much land that is increasingly needed to support the growing population. Not an option.
- Aerroon 5y agoSome numbers: The US Forest Service estimates that 1 acre of forest stores about 80 tons of carbon. You could store about 180 billion tons of carbon onto that area if it were all a forest. CO2 makes up about 3 trillion tons of the atmosphere. ~27% of it is carbon, therefore there is roughly 800 billion tons of carbon in the atmosphere. It seems plausible that if we somehow planted a forest on the entire Sahara desert, that we could reduce the amount of carbon in the atmosphere by a significant amount. I hope I didn't make any errors in my calculations.
- SyzygistSix 5y agoThe reduced albedo effect from the no longer radiant Sahara would cause a significant amount of heat absorption. While it would remove CO2, for a while, the increased heat would be enough to almost offset the entire benefit from the project.
- Aerroon 5y agoThis is not something I considered at all! If this impact is so large, then would having more clouds significantly help with warming?
