An interesting plot:
For everyone out there who's arguing that the Hunga Tonga volcanic eruption added a lot of water vapor to the atmosphere, here's a plot of total atmospheric water vapor (60N-60S). I've removed the dates on the x-axis, so please tell me when the eruption occurred.
I deleted my response. Not being able to answer your question, I looked at a number of sources to see if I could find an answer. Failing that, I quoted some stats on the volcano. Now I'm embarrassed because the eminent Professor Katherine Hayhoe ticked me off. 😒
