And it's all caused by us mean old humans, not the fact that Recent massive volcanoes have risen from the ocean floor deep under the Arctic ice cap.

I believe those are recently discovered volcanos. Doesn’t mean they haven’t been there all along.

Yes — they don’t tell you that these massive volcanoes are belching enormous amounts of lava and CO2 !!!!
Enormous amounts!

I was reading about that 1999 volcano eruption. I`m not a geologist, but the Arctic is so vast in size I doubt an erupting volcano would have much impact on Arctic water temps, except maybe the water close to the eruption. And that would probably be for only a short period of time.
