In my PhD studies, this work has gone a lot further into the area of ecosystem management techniques based on the ice age records, snowball Earth theory, and some very elegant electrochemistry. We do not think that blocking the Sun is the long term approach that will succeed and want to coordinate a scale up of our technologies to enable this long term remediation science.
