PROF'S POSER - Up in smoke?

This is firmly in the 'Two wrong's do not...' camp, but I would like to know*:

Do you think the BBC environment correspondent will tell us how much CO2 and sulfur compounds has been released by the Tongan volcano in the last two days, and what % this represents of the sum of similar gases released by annual human industrial activity?

This may bring up an 'inconvenient' fact or two.

It becomes pertinent as one discusses the relative man-worsened aspects of anthropomorphic climate change. I wonder if we will get any discussion, much less answers, from some usual suspects quitekeen on rushing to print and screen with other data when it suits?

*I asked; I may have an answer (if from another source, and an unvetted one for now. And I await, with dread, the publishing of equally valid-looking data that claims the exact opposite) in another blog...

We have injected a trillion (1 x 10 EEX 12) metric tons of CO2 into the atmosphere since 1751, half of that in the last twenty five years, and we are increasing that by some two to three percent per year. Background volcanic emmisions from all volcanoes, including the 60,000 kilometer mid-ocean ridge system, are on the order of 0.2 to at most 1 billion (1 x 10 EEX 9) tons per year, two orders of magnitude less than we, anthropogens all, are emitting per year.

CO2 is up 38 percent over preindustrial levels (280 to 387 ppmv), and has never been above 300 ppmv for at least 450,000 years (four glacial intergalcial cycles).

The search continues.
