Please look at the type of evidence provided to the United Nations in 2007 by Dr Rosiland Peterson (A scientist concerned about the effect of chemicals pumped into the atmosphere as part of Geoengineering efforts on agriculture) showing that geoengineering is taking place. If you look at the man produced chemical clouds which she shows on the presentation to the United Nations you will recognise many of the wispy so called clouds in our atmosphere.

This is an official UN video- people who will bother to investigate for themselves rather than simply dismiss the as a conspiracy theory and simply look at some of the crazy cloud formations will soon realise what is really going on
