Around 19,000 years ago, glaciation was at a peak. Much of Europe and North America was under ice. Then the climate warmed

Evidence has been building that in the past, periods of severe loss of glaciers were followed by a significant spike in volcanic activity....seems only fair, since recent theorizing is that the increased amount of volcanic activity we're seeing is very likely to lead to significant cooling of the atmosphere because of all the particles thrown into air which will block sunlight - it's a cycle which will eventually lead perhaps to increased glaciation and to no change in the overall temperature - see how that works in real life.....
