It is said that if you go far enough to the right or the left, you'll eventually meet your polar opposite on the dark side of the moon.
So it goes with weather modification.
Leftists have for 30+ years been pushing a hoax called "global warming," later renamed "climate change" when the promised warming failed to materialize. In so doing, they assert that man is doing irreparable damage to the atmosphere and the oceans because of excessive carbon dioxide emissions. In response, it is up to government to "do something" to save the planet.
But the far right has its own conspiracy theorists. They assert that all (or at least many of) the contrails (and other curious cloud formations) we see in the sky are really the result of government aircraft spraying poisonous chemicals into the atmosphere ("chemtrails") and that government is modifying the weather via subversive methods.
The left says man is modifying the atmosphere and it is up to government to stop it. The right says government is modifying the atmosphere and it is up to man to stop it.
Both are wrong. No man or government can appreciably affect the weather or the climate, nor alter the state of the atmosphere or the oceans. The volume of the atmosphere and the oceans is much too vast and we're much too small.
Two contrails and cirrus vertebratus. Only this and nothing more.
