Russell Seitz's 'Bright Water' concept is interesting theory that the Harvard physicist has come up with to cool our planet. 'Bright Water' theorizes that pumping tiny bubbles into the ocean will brighten the ocean, thus helping the earth to cool down.
As bubbles in the water are what makes it more reflective, putting these tiny bubbles into the ocean should lower the temperature of the water and the earth.
It may sound ridiculous at first, but there is research that supports Russell Seitz's theory. However, there is a lack of research on the effects of a bubbly ocean on the sea life that resides in its depth. Only until then we will truly know how a carbonated ocean will effect us.
