From Prof. Eliot Jacobson:
Wow! Wow! Wow!
North Atlantic sea surface temperature anomalies are going vertical again. And yes, I needed to extend the y-axis.
Yesterday’s temperature of 24.49°C (76.08°F) was 4.2σ above the 1991-2020 mean. The previous high for July 17 was 23.71°C (74.68°F) in 2020.

No incentive, even for biochar for terra preta.
Gamify it. Everyone starts out with a basic setup. The organization coordinating the effort can add additional incentives. Add achievements, unlockables, larger setups, rare algaes and algae colors. Loot boxes with various supplies. Three factions that compete against each other. Leaderboards, both local and global.
It would be simultaneously competitive and cooperative towards a common goal.
