There are studies by aerosol researchers who have proven that ash particles from volcanic eruptions can temporarily cool down the climate. There are now also reports on the Internet that claim that greenhouse gases emitted are actually accelerating global warming. Does it depend on each individual volcano which effect will be dominant? Could it be estimated today which effect will be more significant overall?
Yes, the gases and dust particles thrown into the atmosphere during large volcanic eruptions can influence climate. Particles spewed from volcanoes, like dust and ash, can cause temporary cooling by shading incoming solar radiation if the particles were launched high enough into the atmosphere but volcanic gases like sulfur dioxide can cause global cooling, while volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming. After cooling volcanic cloud lowered global temperatures by increased by 2- 3 degrees Celsius.
This is utterly WRONG
The main effect of volcanoes is the emission of SO2 into the stratosphere where it is transformed to small particles reflecting the solar energy for years like in the year without a summer
For Pete's sake READ the literature before you jot down your gut feelings
