The globalist elites, Bill Gates being a public example, want to use geoengineering to block the sun, to lower temperatures. What could p[possibly go wrong with this? Plenty, according to a University of Pennsylvania study. The strategy, based upon what happens with volcanic reactions, may not work, since the sulphur emitted by volcanoes produces clouds in the troposphere, which is the region from the surface to 10 kilometres up. But, geoengineering using sulphuric acid would happen higher, in the stratosphere, from about 10 to 20 kilometres above the planet. It is not certain that the same chemical activities would occur. So, if the experiment fails, how is the sulphur then removed? A new problem.
