Oh please. The tongan eruption was about 2 years ago.
Our current heating trend started decades before that. Now you are just grasping at straws.
Water vapour has an effect, but it doesn't stay in the atmosphere anywhere near as long as CO2. CO2 does stay in the atmosphere for a long time, which is why it has a long and cumulative climate effect.
My mention of Volcanoes doesn't contradict the IPCC at all. They are talking about the current relatively stable volcanic environment not having very much effect.
I was talking about prehistoric periods of very high volcanic activity. You would have to be completely innumerate not to uderstand the difference.
