Strictly speaking, the usual answer is – not much.
People who claim that it does may have in their mind the eruption in 1815 of the Indonesian volcano Mount Tambora, which released an estimated 400 million tonnes of gas. It followed four other volcanic eruptions during the three previous years. As a consequence 1816 became known as the “year without a summer“. Crops failed and thousands of people died of starvation.
However the main climatic effect of the eruptions was due to atmospheric dust and sulfur dioxide; as a consequence the effect was temporary – and indeed to cool the climate rather than warm it. This was clearly very different from the rising global climate temperature over the last half century.
Can we believe any PR the ‘Team Machine’ have to issue on weather nowadays Harry?

At least they’ve retreated from the overt mention of global warming to the implied nowadays.
I see I’m not the only one asking the bleeding obvious nowadays-
