Doesn't that make you think about The Matrix?
-----------------
Efforts to reflect away the sun's rays might also make the sky whiter, one of many reasons some distrust such geoengineering schemes.
The white haze that hangs over many major cities could become a familiar sight everywhere if the world decides to try geoengineering to create a cooler planet.
Scientists have long suspected that one oft-discussed geoengineering technique -- shooting tiny sulfate particles into the upper atmosphere to deflect sunlight -- could turn the blue sky white. Nature has already provided a basic proof of concept. When Mount Pinatubo erupted in the Philippines in 1991, spewing tons of sulfate particles in the atmosphere, it temporarily whitened the sky.
Now a new study by researchers at the Carnegie Institution for Science attempts to determine just how big the effect from man-made geoengineering would be.
Adding enough sulfate to the stratosphere to block 2 percent of the sun's light would make the sky three to five times brighter, they report in a paper that will be published in the journal Geophysical Research Letters.
