“ The 1991 eruption of Mount Pinatubo in the Philippines released *thousands of tons of sulfur dioxide* into the stratosphere, temporarily lowering average global temperatures by about 1 degree Fahrenheit, according to the U.S. Geological Survey.”

“ Make Sunsets was planning to…release anywhere between 10 and 500 grams of sulfur dioxide in January”

I hope it doesn’t take years for someone to test the theory with a few tens of grams of this substance unless even that amount can cause harm.
