Chemtrails spraying sulfur dioxide into the upper atmosphere and mimic the cooling effect of volcanoes. Dumping nitrogen to cause massive algal blooms in the ocean to absorb CO2. There are other Dr. Evil sounding stuff among the "fixes" for climate change like artificial trees. How could it go wrong?
The problems with the environment are vastly more expansive than CO2. In my book that Tell me some strategy for fixing the environment that works. I doubt a bunch of smart-dumb people meddling with atmospheric balance of the planet is the solution. They have utterly failed to reduce CO2 emissions worldwide, and created a molecular version of modern day Catholic Church indulgences. How about preparing for sea rise as an inevitable reality beyond our control of the planet. Not to mention that the sun drives the warming of our planet at a fundamental level goes through cycles we will likely never fully understand?
Trying to "solve" a problem without addressing the causes would likely kill most patients in the medical field. Not preventing the illness ensures plenty of patients to patiently be bilked for money until their deaths. How about the conspiracy against cannabis hemp to ensure a market for deforesting the planet!? That was an agenda furthered by racist propaganda demonizing Mexicans and Blacks for the benefits of bankers, industrialist, propagandists and the police state at post-prohibition strength. See the documentary Grass to learn more on this conspiracy fact. Until we face more fundamental issues on the climate of our planet it is easy to point at morons living in historic floodplains and proclaim Armageddon is coming. With all the heavy metals and other disease causing chemikills humanity could be too retarded to care about anything soon. Autism is at 1 in 68 today from 1 in 150 in 2000. Of course claims have been made that they are better at detecting autism so does that imply 1 in 68 is a normal rate of autism?
After the epic failure that is the wars on terror, drugs, poverty and so forth, I am wary of generalizing any quick fix that involves global systems. How is that globalization house of cards doing? We could more sanely spend some money on desalination plants and permaculture. There is a slew of legit causes to fund. But nobody is terrorizing the masses into using common sense. Common sense is not profitable for the people who enslave the globe with media, governments, corporations and the military being middlemen for reality, control, basic human needs and security.
