Marine Cloud Brightening
By artificially brightening marine clouds, especially in the sub tropic regions, the albedo of the planet can be increased where the inbound heat flow is at its greatest.
Our proposition is to do this by using a novel technique with fluidic oscillators which allow fine salt water sprays to nucleate clouds and thus increase their albedo or create new ones. In addition, this also converts water vapour from a potent greenhouse gas into reflective clouds thus amplifying the effectiveness.
The use of fluidic oscillators is the most energy efficient, reliable and controllable way of achieving this objective. Computer modelling has demonstrated that if this is deployed at scale in the subtropics, it will be able to offset the heating being caused by a doubling of atmospheric CO2. By deploying this in the subtropics heat is most effectively blocked from flowing into the planet.
The ultimate effect of this will be to prevent the excessive heat from flowing into the Arctic which then gives the ice cap a chance of being re-established.
This proposal effectively replicates the natural processes of marine cloud formation, in as much that marine clouds form from natural born salt particles being released into the atmosphere from wave action produces and dimethylsulfide from phytoplankton. As a consequence ocean surface heating phytoplankton growth is seriously depleting reducing a major source of cloud nucleating particles.
Of the three interventions that we propose, this one has the fastest time constant. By this, we mean that the time taken for the planet to reach thermal equilibrium following its intervention is the shortest. This is a vital consideration, as there is a time constant working in the opposite direction due to the time taken for the planet to reach thermal equilibrium from the CO2 increase. Analysis of temperature changes since the industrial revolution suggests that a time constant of at least 30 years exists between CO2 increases and temperature rises, hence the catastrophic temperature rises that we are experiencing today are the result of CO2 emissions from the 1980s. Since then, the same amount of anthropogenic CO2 has been added into the atmosphere as had been emitted up to 1980. We thus have extreme heating already in the pipeline and coming towards to us at a time when the ecosystem is even less able to cope.
It is undeniable that the planet will have to be cooled. If Marine Cloud Brightening is not used, other more aggressive and dangerous approaches will have to be used in its place. The most likely of which is SO2 dispersion in the upper atmosphere. However, this is an extremely high risk strategy. High level SO2 could destroy the ozone layer and return far larger regions of the planet to the curse of acid rain than was ever the case in the past. The net effect of a destroyed ecosystem would be to reduce the level of CO2 sequestration and ultimately amplify the crisis that it is trying to solve.
