I'm not sure but I'd be willing to be the emissions from the 24/7 military aircraft everywhere for years straight dumping even worse stuff than the CO2's they emit at the same time is the highest level. The very psychopaths who use the military throughout the world through instruction from governments worldwide do this with much money contributions from places like Google, Microsoft, Apple, Hollywood etc are the ones who started this crap including the activist groups to begin with. Those in charge of the politicians worldwide who are mostly, outside of the individual psychopathic/sociopathic narcissist politicians themselves, on puppet strings controlled by the shadow demons of the Illuminati for example George Soros, Bill Gates, Warren Buffett, Bilderberg group, Skull and Bones, Freemasonry etc. Conservative peon people like ourselves either deny climate change altogether or point at the chemtrails don't follow their directions on how to lessen it so we're the enemy. The left are especially mind controlled through schools, entertainment, media etc and some politicians and celebrities are microchip pedo. Illuminati does black masses on the super famous celebs like Swift, Gaga etc so they're either chipped, monarch mind controlled, controlled by their own greed, addiction, crime or terrified. NASA, NWS, WHO, CDC, FDA, NOAA, National Geographic, Encyclopedia Britannica etc gained much trust over decades for the sake of blinding even many conservatives to their own party saving the day and/or globalism. Christians need not fear. Others should without Christ because they can't stand alone or together. Jesus said the deception would be so complete that even the elect if possible would be deceived. Most churches are either lukewarm, WOKE/liberal theology/Emergent, name-it claim-it/prosperity crap, seeker-sensitive/easy believism, works only, Catholic/Orthodox etc. 5 point Calvinism is insidious & VERY dangerous to rooted Christians that aren't totally rooted in the Rock. MacArthur, Piper, White, Washer, Baucham etc are clever subtly catholic nuanced Gnostic devils. Fact check EVERYTHING with God alone in prayer time. He'll give us all we need but we must ask for wisdom & discernment. James 1:5
