Yes you are right, chem-trails and cell phone towers do have direct impact on the environment. Both of those technologies are relative new compared to the amount of carbon we have been putting in the atmosphere in the last 120 years. Since the start of the industrial revolution coal, oil, and gas has been the fuel on which our leap of progress has been built. Steal factories churning out tons of pressed medals and beams that ship, train, and skyscraper builders have used to make everything from the supporting structures, to the engines have been manufactured, built, or produced. The hundred of millions of tons of coal; the billions of barrels of oil, and multi millions of cubit feet of gas have all resulted in one thing. Carbon. A tremendous amount of carbon that has established itself in upper atmosphere of our planet.
Have there been periods of high carbon in the atmosphere in the past? Yes. Those were times in which there was large volcano eruptions and other geologic differences than we have today. (Today meaning the last 13,000 years) The only thing that can account for the amount of carbon in our atmosphere today is what man has put there. That has been directly associated with he burning of fossil fuels. In the past 120 years, man has also been responsible for the removal of all the old growth trees. There are some forest left but even the rain forest in Brazil are being destroyed. A few years back I was in Honduras and I could not believe how few few trees there were. This was Central America. It should have been jungle.....and in places where they left it alone, jungle did return; but for the most part what trees were there were used for fuel to cook meals.
If I had my way, I would make solar panels cheap enough that even the poorest person in the poorest of poor countries could afford them and would use the power produced to provide for the essentials for their homes. (heating, cooking, lighting, etc). I want to believe that there are other technologies out there that are also going to be alternatives to oil, gas and coal but yet to see such make it to the market place. I hope and pray that we will see those changes in this life time.
In the meantime, we have to deal with extreme weather that has gotten bad and indications are is going to get worst.....until we drop our dependency on carbon based fuel. The Prince of Iran once said that oil was to precious a commodity to use as fuel for cars. Oil is used in manufacturing for 1000's of products. It's beyond time that we move the planet in a low carbon environment.
Just as a side note, I have not noticed as many chemtrails this summer as I have in years past.
