There is a program by Rockefeller and his NWO-fellowers for reducement of the global population by some billions(!).
These gays think on a global scale for decades. Chemtrailing is one part of this agenda. Several effects are avieved:
- weakening the vitamin D production of humans throug reducement of natural sunlight.
- poisoning the ground for disturbing the plants abilit to grow.
- poisoning the humans for weakening the immune system and vaccaine the ppl with nano-particles and heavy metals
- creating (influenca) deseases within the population
- creation of a 'stratospheric shild' that can be electromagnetical influenced by Tesla technology. the creation of earthquakes and the manipulation of human brain activity is archieved.

3.2.2 Aerosols in the stratosphere
In principle, adding reflective sub-micrometer aerosols to the stratosphere is a good method
for reducing SW solar radiation because these aerosols are inexpensive and can have a
significant effect on SW radiation (Budyko 1982). In addition, stratospheric aerosols have
a relatively long lifespan of 1 – 2 years (primarily due to the lack of rainfall) when compared
to those in the troposphere which have a lifespan of lesser than 1 week. The effectiveness of
these aerosols has already been confirmed from observing “natural experiments” in which
major volcanic eruptions caused 1° of global cooling by adding 1 million tons of sulfur (asSO2) to the stratosphere, where it was converted into an aerosol (Lacis and Mishchenko 1995).
This CE technology, which has been the subject of a relatively long-standing debate (Budyko
1982; Dickinson 1996; Teller et al. 1997; Keith 2000), became especially popular owing to the
work of Paul Crutzen (2006) (Wigley 2006; Rasch et al. 2008b). The method has considerable
potential (a reduction of many W/m2) and is in principle effective enough to offset a multiplication
of the pre-industrial CO2 concentration. Modeling studies have supported the effectiveness of
the basic method and discussed it’s possible side-effects (Govindasamy et al. 2003; Rasch et al.
2008a; Murphy 2009; Lenton and Vaughan 2009; Heckendorn et al. 2009; Jones et al. 2010).
However, as Heckendorn et al. (2009) and Pierce et al. (2010) show the method’s effectiveness
does not increase in proportion to the amount of sulfur that is added to the stratosphere. The
initial estimates of amount of sulfur that is required have already been revised upwards (Katz
2010) and the expected stratospheric lifetime of the aerosols revised downwards (Tuck et al.
2008). Although, Pierce et al. (2010) suggest avoiding these difficulties and the undesirable
warming of the lower stratosphere by directly deploying a sulfuric acid aerosol over a large
area. Unfortunately, the technical challenges of getting large amounts of either sulfur or sulfuric
acid to a height of 20 – 25 km are considerable.
There have been many proposals regarding the technological implementation of a stratospheric
aerosol shield. One patent filed in 1991 addresses the insertion of aerosols into the stratosphere
(Chang 1991). A more recent patent is for a method that uses commercial aircraft to deploy
reflective aerosols by adding a special additive to their fuel (Hucko 2009). The Microsoftfunded company Intellectual Ventures has promoted the development of a method called a
“stratoshield”, which uses a balloon to carry a tube from the ground to the stratosphere to deliver
the aerosols, or aerosol generating chemicals, by pumping them through the tube. Keith (2010)
has also proposed to use photophoretic forces to increase the concentration and lifespan of
certain reflective particles in the stratosphere and to reduce their effect on ozone chemistry.
The side-effects of stratospheric aerosol injection have been debated in a number of
publications. Many possible negative effects on the global hydrologic cycle have been deduced
by comparing the proposed stratospheric manipulation with the largest volcanic eruption of
the 20th century, Mt. Pinatubo (Hegerl and Solomon 2009). Simulations by Ricke et al. (2010)
suggest that it is not possible to achieve cooling without changing precipitation patterns.
However, using GCM simulations Irvine et al. (2010) more optimistically suggest that it is
possible to reduce solar radiation with only minimal regional effects on precipitation. Other sideeffects also include those caused by the potentially catalytic acceleration of ozone depletion by
stratospheric particles (Heckendorn et al. 2009). Adding sulfur to the stratosphere would also
increase the acidity of rainfall in the vicinity of the addition. However, according to modeling
studies by Kravitz et al. (2009; 2010) the global effects of acidification would be negligible.
To minimize the negative side-effects of adding these aerosols Ban-Weiss and Caldeira (2010)
and Eliseev et al. (2010) propose that this method can be optimized by evenly distributing the
aerosols across different latitudes. However, not all side-effects are negative; one positive sideeffect is that these methods would increase diffuse solar radiation, which could have a positive
effect on plant productivity (Roderick et al. 2011; Mercado et al. 2009).
