"Approximately 2% of the solar radiation reaching Earth must be blocked to offset the predicted greenhouse trapping in the next century."

"An ideal opaque shield would scatter the Earth bound solar energy into diffuse infrared energy."

"shields for planets such as Venus or Mars would... be large, complex structures requiring vast amounts of lunar or asteroidal material... and long-range transportation... One... stepping stone to understanding and mastering the technologies and processes... would be the construction of a shield to offset the greenhouse effect on... Earth. Such... would not require interplanetary capabilities."

"The shield may also be transparent and simply scatter the visible photons away from the Earth. ...A glass shield may act as a prism to deflect the sunlight away from the planet in accordance with ."

"The cultural tasks are... possible to fulfill. For example, if a sea route to the ports of Siberia is to be kept ice-free, a route must only be chosen that runs approximately in the direction of the winter wind from the Gulf Stream... light is thrown on a relatively narrow and short strip running from east to west... to the extent that the sky clouds over at this place. ...[T]he direction of the wind and ...the earths rotation coincide. Hereby the earth always rotates as we need it ...By the time the light patch has passed along the whole stretch, the fog at the beginning will either have settled or been blown away... Then one can begin at the beginning again, Since the clouds hold the heat above the shipping lane... a reflector 100 km in diameter is... sufficient."
