H.A.R.R.P. is a dangerous high power high frequency device. There are over 20 such devices work wide part of a global weather war system. There is a lot of misinformation and even more information being kept secret. The Propaganda is winning.
Actually, I spent several days investigating the HAARP facility a few years back during Dane Wiggingon’s scare campaign about it. And as an RF and antenna engineer, it didn’t sum up to the hype, IMO. Last time I looked it was a facility that had lost its government project support funding and was advertising itself out as a TEST BED for RF experiments involving RF atmospheric investigations to other agencies and contractors.
And, IMO Mt Pinatubo had nothing to do with HAARP or any of the other “20 such devices” worldwide you mentioned - it was an internal geological volcanic event unconnected with any possible atmospheric RF event such as HAARP.
Volcanos release more cooling emissions than green house emissions.
Now, in regards to CO2, on average human activity globally emits MORE CO2 per year than do volcanos, globally. A few years back I did the calculations based off figures for production of fossil fuels from major source countries, and an estimate, 10% IIRC, for minor sources. I also sourced estimates of volcanic emissions going back to when fears of an imminent ice age were bandied about. Try it.
