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.
here's the answer, with HT's eruption marked as the dotted line. as you can see, it injected a trivial amount of water vapor into the atmosphere. it was unusual only in that it injected it into the mid-stratosphere, but water vapor there has little impact on the climate.
