A gigantic volcanic eruption could save the planet from global warming caused by climate change. That is the remarkable conclusion of many scientists who say that studying such an eruption could help us figure out a unique way to counteract the effects of global warming by using aerosols to reflect solar radiation back into space.

Volcanoes have led to global cooling events in the past, including just a few decades ago when Mount Pinatubo in the Philippines blew its top in 1991, causing global temperatures to drop by a ful degree Fahrenheit for two years. The rock and ash spewed out by a volcano mixes with water vapor in the air to form aerosols, which act as a reflector and send the suns rays back into space.

That is why scientists think that we should study the next big volcanic eruption intently, as it could help us figure out how to understand these aerosols and how we might be able to spread them over the globe as well through jets or some other method.
