A question on AGW?

I was thinking today about AGW after analysing the figures from White Island.

I then checked up about the "Hockey Stick" and am a little perplexed.

Does the "Hockey Stick" include Krakatoa, Mt St Helens, Pinatubo and Mt Etna to name but a few greenhouse spewing volcanoes?

Can anyone tell me?

I have added the key dates to the Hockey Stick graph and all except Krakatoa are in the steep incline. Krakatoa is actually just prior to a steep decline.

So what is the answer. Clearly I am no scientist, but isn’t it just possible that AGW is bollocks and completely unrelated to massive amounts of Non-AGW Greenhouse gases spewed by eruptions and active volcanoes. Look at this graph of Atmospheric CO2 from Mauna Loa in Hawaii.

Humans certainly haven’t caused that to increase. I couldn’t find any conclusive evidence to show that Volcano activity has contributed or not contributed to Global Warming or to Global Cooling. The evidence suggests from it dearth that it in fact hasn’t been considered in any of the AGW arguments. I know, I know, Volcanoes aren’t man made, they do however emit tonnes of Greenhouse gases that make man made emissions seem insignificant.
