Hawaii Volcano Sulfur Dioxide Emissions vs US Total Emissions.

With the decline in coal burning, sulfur dioxide pollution emissions in the US mainland have dipped down to about 3 million tons a year in recent years. On the other hand, based on the measurements taken with the geological model adopted over the past year, sulfur dioxide emissions from Kilauea's vents within the Hawai'i Volcanoes National Park may be over 2 million tons a year. So the National Park Service, in Hawaii, remains our country's biggest emission source of sulfur dioxide, a cause of acid rain.

Anthropomorphic climate change is but part of a much bigger system of the earth's crust and atmosphere that remains dynamic with or without human outputs.
