Any reader of this paper will already know about increases in atmospheric CO₂, Arctic ice loss, methane release, carbon embedded in imports and the progress to date of our world leaders in finding solutions to these problems. This paper describes some of the engineering ideas needed to implement a proposal by John Latham to increase the reflectivity of marine stratocumulus clouds by an amount necessary to offset the thermal effects of increased greenhouse gases.¹ 

The power density of the solar input at the top of the atmosphere, not quite constant, is about 1360 W m⁻²....
