Hi Robert, Thanks for responding to my points. I now have a better understanding of your approach. I appreciate that to start the ball rolling you need to promote the algae with plenty of CO2, light and nutrients in a controlled environment. But then the algae must be able to continue to do their work in oceans, lakes and even wetlands, where they can drawdown CO2 and provide food for other creatures in the food chain. I am especially interested in promoting methanotrophs which suppress methane, a potent greenhouse gas whose level in the atmosphere has been growing alarmingly since 2006 [1], threatening to boost global warming well beyond safe limits. The need to focus on methane has been highlighted by Mike MacCracken, known to some of us on this list [2].
The need to prevent dangerous climate change is so vital, that I would not rely on finding commercial projects, but fund activities through a carbon tax, levied on the businesses which extract carbon from the ground. Thus these people would be funding for repair of damage they cause: putting carbon back into the ground which they had taken out of the ground. That would be climate justice for me!
