Well that is if you believe the growing chemtrails conspiracy theory anyway.

Millions of people, including pop and film stars and politicians are convinced a secret global conspiracy is taking place in front of our eyes on a daily basis.

The Chemtrails conspiracy theory is one of the most supported on Earth and counts the late pop legend Prince and movie legend Chuck Norris among its high-profile advocates.

At its most bizarre extreme, conspiracy theorists believe that the contrails which form behind jet aircraft are actually streams of toxic “mind-control” chemicals, which dilute before they reach the ground, leaving a gas we breathe in that keeps the general population in check.

But there are a growing number of chemtrail believers, who claim the it is actually a secret global plot to change Earth’s climate in the hope it will reverse the effects of climate change.

Dane Wigington, a solar energy expert and former employee of Bechtel Power Corp, now runs Geoengineeringwatch.org, a website set up to expose the “harmful” conspiracy which has had more than 22.3 million visitors.

He investigated why solar panels at his home lost power as aircraft contrails formed in the sky.

According to Mr Wigington, the contrails, or chemtrails, we see forming behind aircraft most days are carrying out geoengineering.

An introduction to the subject on his website states: “It sounds like science fiction, but it’s not. It’s happening right above you."

He said a system called "Solar Radiation Management” (SRM) was being used whereby scientists have tried to mimic the effects of a major volcanic eruption on temperature.

During an eruption, the sulphurous ash clouds would block out sunlight, cooling the Earth.

He said: “Their concept is to mimic the dimming and cooling effects of a volcanic eruption and existing particulate pollution made by human activity.
