The Blanket Effect is intended for others to learn about weather modification and its related subjects in an easy to understand way. Started in 2005, this blog is a work in progress as the technology advances

Questions from an Expert

(note: Below are excerpts  from an article by G. Bala, printed on January 10, 2009. Although Mr. Bala apparently is a frequent contributor to  climate research, in this paper he cites his reservations about using atmospheric aerosols (chemtrails)  in the fight against global warming.  Keep in mind that chemtrails of unknown chemistry are already being deployed every day  and nearly everywhere, under the military and 'scientific study' umbrellas.)

Problems with geoengineering schemes to
combat climate change (PDF)
Author: G. Bala

The possibilities of deliberately bringing about countervailing climatic changes were suggested in the 1965 US President's Scientific Advisory Committee report. 


About ten years later, methods based on increasing the aerosol content in the lower stratosphere for climate modification were proposed by a Russian scientist, Budyko. Sulphur could be injected by aircraft, rockets, or missiles.

An alternative to direct injection [of sulphur]  is to increase the sulphur content of the jet fuel.
The main concern raised by Budyko was about its effects on the ozone content in the stratosphere.

A large number of flights in the stratosphere can also lead to changes in the stratospheric climatic conditions.

Sulphur injections in the troposphere were [also] not recommended by Budyko for the following reasons:


Aerosols in the troposphere have a lifetime of only weeks, while stratospheric aerosols have a lifetime of 1-2 years; tropospheric injection would require 100 times more sulphur than [stratospheric] injections.
