Researchers say seawater mist could counteract global warming

What if it turns out that slashing carbon emissions enough to make a difference is economically and politically impossible? Do we need a Plan B? A small but growing number of researchers are beginning to say 'yes.' One method includes spraying seawater mist from ships toward low-lying clouds, which would then reflect more sunlight. According to the new paper by Lee Lane and J. Eric Bickel of The University of Texas at Austin, the seawater-mist method could counteract a century's worth of warming for $9 billion.
