Cloud whitening is a modern scientific
method of global warming prevention. It is a relatively new method
but based on a fairly traditional and simple idea. Clouds prevent the
suns rays from reaching particular places. Consequently these places
are somewhat protected from the direct immediate effects of global
warming. Cloud whitening involves the artificial creation of clouds.
The clouds themselves are not artificial but they do not occur as a
consequence of nature, as they usually do. Instead, the clouds are
created by machines.
The mechanical process too, like the idea, is
rather basic. Simply enough it involves a funnel spraying seawater up
into the air. Microscopic particles, converted from seawater, are
sprayed towards clouds which then increase in density.
involved in the project declare that this is the most obvious way of
creating clouds. These clouds then protect the earth's surface from
the radiation of the suns rays, by reflecting the suns rays away from
the earth's surface, contributing to the battle against global
Recent stories indicate that Bill Gates, of Microsoft fame,
is the major figure behind contemporary cloud whitening plans. Bill
Gates has supported the research into cloud whitening and what
benefits it can have. Gates has financed the research independently
of Microsoft. Campaigners against cloud whitening, which has become
simultaneously associated with Bill Gates, stress that the strategy
is too risky. Some of the various concerns about cloud whitening
include the effect the process has on rain production, moisture
circulation and its impact on ecosystems.
Silver Lining, a research
group based in the United States, is developing the machines capable
of converting the seawater and spraying it into the air. The group
has plans to trial the system in the sea. The plans involve hundreds
of ships and will take place over an area reported to be 10,000km2 in
One of the benefits of cloud whitening is that the process can be stopped or started reasonably quickly. Once the process is stopped it takes just over a week for the effects of cloud whitening to disappear, meaning it can be cancelled quickly if the process encounters problems or opposition.
