Alaska Volcano Observatory

Wow, Alaska actually has a volcano observatory (Alaska Volcano Observatory), how cool is that?!

They even have webcams for each of Alaska's volcanoes. Two for Redoubt, supposedly about to erupt, one from sea level in the Cook Inlet, and one from a hut at a much higher elevation. Redoubt is at aviation code "orange." There are two other Alaska volcanoes at code "yellow": Cleveland and Shishaldin.

If Redoubt does erupt, I wonder what the impact will be on global temperature for the Arctic region and even the whole Northern Hemisphere over the next two years. All of that particulate matter will tend to cool the lower atmosphere. Sure, it will only be a temporary impact, but it will reduce the number of climate change "records" set in the next two years compare to those records supposedly set in recent years.

Needless to say, I am fascinated by volcanoes.
