- galangalalgol 5y agoI still think iron fertilization is the best bet, not for co2 removal, but for albedo modification. Keeping equatorial kelp or algae mats alive would prevent lots of energy from entering the system. Those mats have albedo close to snow in the infrared, where water is about as absorptive as it gets.
- detritus 5y agoI wonder if we could somehow use strategic placement of fertilisation to encourage processes that laterally help in cleaning up (/collecting) plastic pollution in oceanic gyres? A girl can dream. - ed: I am fascinated by the idea that otherwise horrid floating plastic pollution can act as centres for bio-accumlation leading to local, floating bio-domains. I guess the real problem is plastic bags and fishing nets, not toothbrushes that happen to float.
