A volcanic eruption is being blamed here for global warming. However, there are reports that the ash particles reflect sunlight and cool the climate. It probably depends on the composition of the erupted material:
Years ago I read scientific analyzes of this by aerosol researchers. If a larger volcano erupts in the tropics, the temperature can be cooled down by an average of 0.5 degrees for two years - if I remember correctly.
The question now is what type the majority of larger volcanoes are - will they emit more ash particles to cool them down or greenhouse gases that actually promote global warming? Can anyone theoretically predict this through appropriate research and analysis, or is it still too unknown what type of eruptions will be in the future?
