Jury duty is done, so here is a little update.
Redoubt is puffing away, producing a more prominent steam plume than it has over the last week (but that may be more weather-related than magma-related.) Beyond that, the volcanic gases keep coming and the earthquakes keep coming.

Gerhardus, I wonder the same thing. I remember that in August, 1992, my area had snow around the middle of August. It stayed cold from that point right through winter. I have never seen this before or since. Experts later said it was caused by Pinataubo.
From what I have read, emissions from Alaskan volcanoes have great potential to disrupt human activity because the ash and emissions can travel further at that latitude.
As for H2S and other emissions, that is a good question. The 1912 eruption of Novarupta, AK, dissolved laundry on clotheslines in Vancouver, Canada, three days after the eruption. For 40 years, it was believed that Katmai was the source. Novarupta had apparently sucked out the magma chamber from Katmai, causing it to collapse. A Novarupta-style eruption today would disrupt air traffic all over North America, not to mention causing health problems. There’s always that ominous line in history books: “This could happen again.” I don’t think anyone believes Redoubt is another Novarupta. Pinataubo was smaller than Novarupta.
Someone told me that the metallic content of the volcano is a factor in climate change. Each volcano has its own metallurgical signature. Dr. Klemetti? -

Point taken (pardon to the ladies) your explanation sounds real fair. Just wondering how much is a major eruption going to influence the current somewhat hectic weather patterns in the northern half
What will the influence be if it’s a minor one and what if it’s a major eruption
How much ‘polutants’ normally being released in a eruption if it’s compared to the human emissions eg. one eruption like st Helens compared to human daily emissions -
