Climate experts say a fleet of wind-powered ships could be one of the more feasible solutions of climate engineering to reduce global warming. The Copenhagen Consensus on Climate has released an analysis paper that addresses a variety of proposed climate engineering options.
The paper was written to address the question: “If the global community wants to spend up to, say $250 billion per year over the next 10 years to diminish the adverse effects of climate changes, and to do most good for the world, which solutions would yield the greatest net benefits? – i.e. what are the costs and benefits of different viable climate interventions…given some reasonable assumptions about sensible policies for the rest of 21st century?”
One of the most popular options among experts would be to deploy a fleet of 1,900 wind-powered ships that would draw water from the ocean to produce plumes of seawater mist that would create white clouds. Scientists predict that the clouds would be able to reflect about 1 to 2 percent of sunlight that would otherwise be fixed on the ocean, adding to its temperature. The concept has been largely embraced due to its estimated cost not to exceed $9 billion, which pales in comparison to the $250 billion to be spent by leading nations each year in order to reduce carbon emissions. The project is also much cheaper that another engineering option that would send mirrors into space to deflect the sun’s rays. Additionally the cloud ship fleet would be ready to begin within 25 years. The Copenhagen Consensus Center is an organization that grants advice to government regulators on which areas to spend financial aid.
